How to use Oracles VirtualBox on Windows 10 (Step by Step Guide)

PaulAugust 21, 2021

What is VirtualBox?

That is the first question you should be asking your if you are wanting to use it. VirtualBox is a way for anyone to play around with other operating systems like Windows 11, and yet I didn’t like it enough to even think about playing around with it on a Virtual machine. You can also install different Linux operating systems to get yourself used to the Linux OS. Either way, the long term’s of using VirtualBox is vastly better than you can imagine. You can try new Operating system and see how they will do with what you might be interested in. This will be a how to on Windows 10 because that’s what I am using but I have already talked about doing it on Linux and installing Windows 10 on it. If you’re curious about doing it the other way around that would be a good start.

After Installing VirtualBox in Windows 10

What’s the first Step in installing an operating system. You either need the USB version or If you have a DVD of the operating system you want to install that will also be good. Each way is not to hard to do while using VirtualBox. First part of this is to initialize the Virtual System.

You’ll want to click the NEW button and you’ll be lead to this screen. Give it any name you would but most will say something like MacOS, Linux, Or Windows (xp, 7, 10, 11) because you would basically like to keep track of that when you start using the Virtual machine.

VirtualBox is pretty intuitive when it comes to which operating you will be installing so when you name it the right Operating system. You should see the version and type change down below to reflect the type of operating system parameters you’ll need to use the Virtual machine.

Dedicating the memory

You’ll want to dedicate a certain amount of memory to be use with VirtualBox so you can have enough to run the virtual operating system and not be sluggish. If you have 16 gb or more of memory than you can easily divide it by 2 if you are just going to do one virtual machine at a time. The Minimum I would recommend to use with a Virtual Machine is 4 gb but that is just a personal opinion.

Create a Virtual Hard drive

This is simply the easiest part of the creating the virtual machine. You can have use as much as you like or as little as you like depending on your situation. I usually give mine at least 10 gb or more depending on which operating I will be installing. The more space you give the less you will have to use on your local hard drive so if you have another drive you want to use so as to not fill up your C: drive that would be preferable.

You’ll want to create a VHD or a VMDK but I rather like just useing the Virtual Hard Drive selection because it makes it so much easier for me.

This is where you should say Fixed size, so it doesn’t use up so much space that it will create a problem for you later on.

If you’re unsure of how much to use just keep it where it is. Most of time when you are just checking out a operating system you will not need to much space to test it out. All you have to do now is Create the Virtual Hard drive and you’ll all setup for the next part.

Installing the Operating system

The next step is to tell tell VirtualBox which ISO you will be using to install into the virtual machine. You’ll want make sure the new machine you just created is turned blue by click on it and then hitting the settings key on VirtualBox dashboard.

Finally you’ll want to hit the little disk drive at the top right and add a new ISO you are wanting to use for the virtual environment.

Simply hit the ADD button and navigate to where you downloaded that ISO and use that then click choose. Once done then you are all set on this part of the setup.

Don’t forget about how the cores

This is not a big issue but sometimes might help with running the Virtual Machine by checking to see how many cores you might want to use with the new operating system. This is however just something I’ve found to speed up the virtual machine. If you have 2 cores you can obviously only use 1 but if you have more than 2 cores it can be nice to use a few more cores to make the system a little bit more responsive.

You are all set

This part is obviously the hard part is to just hit the start or double clicking on the virtual machine you want to make it execute. Either way sit back and play around with what you can do with the new operating system and install it on to the virtual hard drive and you’ll be good to go. Once you install, you can go back to the storage selecting in the settings and remove the ISO to prevent it from loading again. In some cases it will so just go back and remove the ISO from the drive and you can just enjoy playing around with whatever system you want to explore.

What is Virtualization and why Do you need to know it?

PaulAugust 19, 2021

Virtualization

Virtualization, what does it really mean? Let’s walk through what the word means and then we can talk about it some more. Virtual is like you are attending a class remotely because there is no real materials or even books that you can use to feel or see. Let’s talk about realization, This is the part that people sometimes do not understand when they hear the word virtualization that the system that is doing this will need to also realize that the system. It’ll need to create a motherboard, CPU, memory, display, ports, and USB ports, and even hard drives and peripherals. It however isn’t really anything that can be touch or even seen by us the user. It is all inside a computer being made by the computer to fool the operating system that is being created by the virtual machine.

Cloud computing

What is that word and what does that have to do with virtualization? I am sure everyone has asked that at one point or time and they might want to know about it even more. Cloud computing is basically a lone server or it could even be a service for companies to use somewhere around the world to create an operating system for the business to use such as Windows 365 which lets you create a Windows desktop virtually on a server to be able to do everything you can do on physical system as if you had one there right now. Play games, edit documents, write emails, and so on are what it is called to be cloud computing. Just think of it as being a computer on the internet and you will start to realize that it is not a real computer.

Do we need virtualization?

In all we do now, virtualization is going to be more and more used in now than in the old days. It allows corporation to manage desktops around the world and not have them physically there. The cost of having a desktop will not be overhead and they can have a server have several people on it and cutting the cost of have having to buy the computer parts or even the computer for the employees. They can then buy really cheap computers that don’t take up as much space and these cheap computers will most likely be underpowered. In the process, they can use that to do what might need to be done on the virtual machine. It can seem like a lot but in the end the computer they bought isn’t as expensive as buying a system that can do what a cloud computer and is far more manageable to the IT staff. They can keep it running and if something happens they can call the company and get someone there to fix the problem that they can’t do.

Benefits Vs Cost

Here’s where it get even better, because if you really think about this as being a virtualization as service, you’ll see that the benefits verses the cost of using one is probably going to be less than you think. Let’s break it down in further for you and explain why in so many ways. Virtualization is basically meaning several computers can be on a really beefy server. It can be a beast and can be used to utilize the CPU processing when it is need to do something like graphics or even just programs that might need the processing power. It could in theory also be used to mine bitcoins or even Ethereum but I really don’t know if it is actually be done like that on a server because you’d only want one system on the server to maximize the chance to mine a bitcoin or an Ethereum coin as they say. Because the more people on that server the more processing power will be divided to the the people equally so that’s one thing to consider. We could look at cost of buying a server or even renting a server but in reality what we need to look at is the idea that the server can host several employees or people on the server to do tasks that remotely or even at the office that will far out way the cost of buying a bulky computer and having the employee’s be in the office all the time.

This is all the definition of what a computer is in the cloud, we just have to think of it as a way to illustrate what it is and why we need it. Do you agree or disagree, do you think I did a good job describing it? Why not leave a comment and tell me what you thoughts or if you think I could of talked about something more. I’d love to hear you thoughts on this matter and others.

Why I uninstalled Microsoft Windows 11 Preview build?

PaulAugust 17, 2021

I reinstalled Windows 10 and Deleted Windows 11!

I don’t know about everyone else but after my week long expedition into Windows 11, I just couldn’t handle the speed issues of the Windows 11 and the encryption. I know it isn’t worth my time after all that to down grade to Windows 10 but I I felt it wasn’t going to get any smoother than that. I also would of had to have deleted the partition anyways since it was locked to secure boot and UEFI. I really didn’t want to try to convert it back to MBR. I got my trust Windows 10 DVD and started it up and found the partitions I wanted to delete and then I reinstall Windows 10. I will say that after wiping the hard drive and reinstalling Windows 10, and turning off all the Encryption crap and just booting into Windows has seen my load times go back to normal.

Windows 11 Problems

First off the main problem I had with Windows was the need to encrypt the Hard drive and I was using a NVME which should of been way faster than a standard SSD or Hard drive to boot up. That wasn’t the case, I’d see the swirling load screen on my system for several seconds and then it would finally boot. Due to the encryption that Microsoft says is required to run Windows 11, it just doesn’t cut it for me. Even playing games like Minecraft was screwy and that isn’t even taking up that much memory at the most 2 GB or if you know how to do it 4 GB. I’d play with Minecraft and the system would take forever to load up the next part of the map or even play Microsoft Flight Simulator 2020 and It wouldn’t be sluggish there also.

The Start Menu

This was something that was just annoying, I think Microsoft wanted to look like an Apple device and bring the apple guys over because of the look. I can’t understand why you would prevent people from reverting back to the old Windows 10 setup. I can only wonder what people will do to find out what they are running and if it will actually be a good idea to keep the start menu in the middle of the screen. Some people have these really long screens and it might help them. I personally would like to move the taskbar anywhere on the outside of the screen, top or maybe right or left of the screen. You wouldn’t be able to do that either. Which will make people really mad.

I can’t see this being all about security

It just can’t be about viruses and malware or even the recent months of ransomware attacks that have been happening in the past year, due to the Covid19 situation around the world. I have talked about how Windows will ultimately fail and we will see virus writers come up with some good viruses and malwares to compromise the Secure boot and even the TPM that is trying to be forced to be used by Windows. I am sure it isn’t over, and if Microsoft isn’t going to change, we’ll see people leaving left and right to go to operating system that are much less restrictive and more open such as Linux. In the end, I went back to Windows 10 because of the speed and performance, and I am not even thinking about Windows 11 until I find out what they will require when the system is finally released. This will be a big deal to some but me, I am not interested in the so called security features of Windows 11.

Understanding Shell Script in Linux Mint and how to use it properly

PaulAugust 15, 2021

Shell scripts are powerful!

Any Admin who has used shell scripts to complete a bunch of tasks on Linux will tell that you should already be using it. It’s something that even I can’t really understand but know a lot about since I have to install Linux a lot. Sometimes it can go weeks before I have to use my shell script again or the next day. It varies from time to time when I will need to use it but it is an admins best friend. Is shell scripts like python, absolutely but there is something that we should at least explore and understand. I am going to talk about this and give examples for those who might want to follow along with me as we talk about “What is shell scripts and how can I use them?”. I am sure this will be a long series maybe a few post here and there but it will be really good for those who might want to learn even more about the world of Linux.

Shell scripts vs python

Let’s at least get this one out of the way, because someone is bound to ask this question. What’s the difference in shell scripts verses python? In the short answer not much, but in the long answer the python language is more complex and you can do a lot more with the python did you can do with shell but only to a point. Each one has it’s own unique qualities and can be used on Linux and Windows. Although shell scripts can’t be run on exactly, they can be renamed to be batch files (.bat) which is DOS(Directory of System) old system. Way before Windows we had DOS and way before any GUI interfaces we had to create batch files to load up the system. If you’re old enough you probably remember autoexec.bat or even the config.sys files that you occasionally had to edit to get to the command prompt.

Shell scripts in Linux

What’s the use of using shell scripts in Linux you might be asking yourself? It’s very useful to use when there is a problem or need to install a bunch of things that would take longer to install individually. Shell script basics are really just that like a batch file in DOS and it can do a lot of things from asking a question to installing many different files. It can rename or remove files, it is also good for cleaning up a directory that might be full of junk files or maybe you want to have a shell script to backup your /home directory. This is the power of shell scripting in Linux. Shell script basics can make your life so much easier and better in the long when you finally decide to delve into the Linux system.

Shell scripts If and then

Just like batch files, you can use this in Shell scripting. If something happens then do this or you can even go farther that by using Else statements also. You can ask something from the admin like where the file location of a file you want to use. It can make your life so much simpler and can help keep the Linux system running smoothly.

if [ expression ] then statement fi
You can do so much more with the shell script when you personalize it to what ever you might need.

echo What is the shell script you want to run? read $FILE if ! [ +r $FILE ]; then Echo "Admin permissions are required to run this shell script" then exit 0

As you can see this can be very useful when you want to get around certain installation situations and needing to install files without prompting.

Here’s a good one for those who might need to do just that:

echo y|sudo apt-get install [apt program]

This will allow you to bypass the yes question when it is asked and you can just create a basic shell script to install the files that you wanting to do like I have from time to time with gaming systems. If you don’t want to wait around and install them manually this is the best approach for people who might want to multiple programs at once.

Executing the shell script

if you can’t execute the shell script than you haven’t given permissions to execute it in Linux. You either have edit the properties in Linux, by right clicking on the shell script and clicking on the properties tab. Then check “Allow executing file as a program” or you can do a command line

chmod 0700 script.sh (only allow owner to run script) chmod 0755 script.sh (Allow owner users, and groups to run script)

As you can see the chmod command can be very useful in Linux, so take care to use it wisely. I will talk about even more about shell scripting in the coming days and hopefully provide you with a very powerful script for installing all the gaming and even the drivers that you might need to for your new Linux gaming system.

More advice for new computer technicians

PaulAugust 13, 2021

Job Searching is outdated!

In My previous post, Some advice for computer technicians, I did talk about what a technician usually has to do to fix or repair a system. He even has to deal with some very difficult customers.

Now with that said I wanted to change directions and talk about the job search area and what you should expect. Being a computer technician that has the educational background but not the experience of actually being a computer technician, can be quite frustrating sometimes when it comes to job searching. It can just make me scratch my head when they require a 1 to 2 or even 5 years of experience to even start doing the job we went to school to get the education to do the job. How is any employer going to over a entry-level job and still require some sort of experience that shouldn’t even be a requirement to get the job.

This just seems like someone is not understanding what the word entry-level means and why it shouldn’t require much to get that job or position.

Don’t Apply for every job

This one just seems like it needs to be said. Just because you have the education, don’t apply to all the jobs that you are interested in before doing a little research. Figure out what you want to do and how much you are worth. Use places like Glassdoor and indeed to make sure the company you are considering applying for has a good reputation or at least got some good reviews by previous employees. You know you will have to deal with bad bosses from time to time, so you can figure out if you want to apply for a job that has a bad boss or if you might just hold of on taking that job or applying for that job.

You are worth more

This one is even better because some people will take these low paying jobs because they want to get their foot in the door or get the experience. I say don’t do it, find an employer who will pay what you are worth. I could go down the street and get paid to bag groceries than maybe an employer who only wants to pay me 12 or 13 dollars to start off on. That just boggles me, that I went to get an education and still can get a job that pays more than what I got my education for. If we stopped allowing them to do this by not applying or accepting those jobs, the pay will eventually go up but we must be able to say no.

Don’t expect that Dream job

I say this with some trepidation that we shouldn’t expect to find that dream job right away. In fact, we will probably have to work at a dead end job for a year or two at the very least to be able to have the requirements to get that dream job. In truthfulness, you could easily find that dream job right after getting your education but the chances on that are slim to none, I’d say. This is something, I’ve seen time and time again that people loss hope right after getting their education to be stuck in a dead end job. This is the time to keep looking for a better job and create notifications to help keep you looking for a better job down the road.

Avoid Job text Bots

This one seems quite common. You get the text that says you’d be a great fit or something along the lines and you ask a question in text and it says “Perfect . . . .“. These are just bots that I have come across, this is how lazy recruiters are trying to recruit people for their job. If anything, his means the job might not be all that it is worth and they are having people quite left and right and this is the easiest way to try to find people to fill the job position. Seems kind of a catch 22 in my book, if they aren’t going to actually read my question and answer it then the job isn’t for me. I’ve turned them off by texting stop when I find out it was bot that answered me or when I get the perfect or some other way to say we want to talk to you before they even read your text.

These are just what I’ve seen in the job market as of late and thought I would talk about some of these and others ways to find a job in the computer repair or a technician jobs. You can even figure out how much a computer technician should make by using Glassdoor or even Indeed to find out the salary rages someone would be making in your area.

What are some things you’ve seen that makes you cringe when looking for a job as a computer technician? Have you seen some of this? Leave a comment below and tell me your experiences as a job seeker. If this post has helped you consider using my affiliate links to say thank you for this great post.
