Just bought Dell OptiPlex Desktop Tower Computer PC | Intel Core i5-6th 3.20GHz | 8GB RAM | 256GB SSD second computer at a pretty good price but not sure which OS it will come with. Probably Win 10 or 11.
I really want to try Linux (thinking about Mint). Can I install Linux over the MS OS, or should I try to partition for dual boot? I don't mind deleting MS, but if I change my mind later, how difficult will it be to reinstall MS? I heard that partitioning for Linux is a bear, and I'm not very PC tech savvy. On a scale of 1 to 10 I'm about a 3.
Which way do you think I should go?
Thanks,
Dave
 


First you can try Linux mint from usb, if everything is ok, I would recommend install mint alongside windows (dual boot). It takes time to comportable with Linux.

Yes, I'll try the usb. I've heard that the usb version is very limited. I've also watched YouTube video instructions for dual partitions and I really don't think I can handle it. That's why I'm thinking about just installing it over the Win OS. Don't you think it would be much easier?
 
It will be easier, but if you want to go back to windows, it will be harder to reinstall windows.
 
The easiest route is to buy another SSD and install Linux on that, and put the Windows SSD away. If you want to go back to Windows, just swap the SSDs. If that's too expensive for you, it's your choice as to whether to keep Windows or nuke it. But storage will be a little tight on a 256GB SSD with both Windows and Linux installed. Partitioning can be troublesome. I would nuke Windows and install Linux alone, but I'm not you. It shouldn't be that difficult to install Windows again if necessary, but I'm far from expert on anything having to do with Windows.
 

If you have the spare cash then personally i would install a new drive and add mint to that, an old HDD will do [the slowest option] a new or refurbished SSD [good performance] or if you have a spare slot for an NVMe for a small one just to run the OS [will bring marked improvements] or a spare PCIx4 slot for an adaptor and NVMe [most expensive option but works as well this is what I use on my HP desktop]

edit, just to add your Dell has the same basic spec as my HP, I have LMDE7, Parrot Home and MX-Linux on this one

My pc, use to run windows. That was 13+ years ago and counting.

I debated, for all of 10 minutes.....and then simply installed Linux. It wiped the windows install like a dirty nose and that was the end of that.

That is the setting that did the wipe job. I saved a large amount of music off windows to an external drive. I still have it and play it to this day.


Make your install/life a little easier?....Go into bios, and Disable Secure Boot and Fast boot.

This is from Dell :
Most newer models show "UEFI only" because the platform does not support Legacy Boot mode.

  1. Under Storage, SATA/NVMe Operation, check that AHCI/NVMe is selected.
  2. Under Boot Configuration, Secure Boot, Enable Secure Boot, check that this is set to OFF. Also Fast Boot. OFF
  3. Click the Apply Changes button at the bottom and then the Exit button.
  4. Under the System Configuration section, SATA Operation, check that the dot is selected for Advanced Host Controller Interface (AHCI).

If any of these do not apply to your particular PC/Laptop, either ignore or ask for guidance for your particular situation.

These two lists may help:

The below details the whole rigmarole. It's long, but should be worth a read.


Install on a hard drive or a solid state drive..(ssd is faster) For Linux, the file system, or format, is usually ext4.


Not something you have to worry about. The Linux installer will automatically format the space you are using for Linux to ext4


The ""oh yea its just like windows , just burn it into a usb stick then boot in bios and boom" "" ....is largely correct....the really Incorrect part is "" its just like windows""....Linux is NOT windows, and never will be.


https://linux.oneandoneis2.org/LNW.htm


The simplest, most sure way to put aside all your fears and trepidation is to ""burn" it into a usb stick then boot it on your PC.... and there you have Linux, LIVE version. (Also known as the Test version....use it to Test out your pc's hardware and also see if YOU like it


Use Balena Etcher to 'burn' the Linux .iso to a 8GB usb stick bigger than 8GB is fine....just not smaller)


(Balena Etcher) Linux Mint Cinnamon/Xfce/Mate LMDE 7





(IMPORTANT....go into bios and turn off secure boot and fast boot. Read below.....

This will not affect any install of windows already on the pc)





To get into bios, tap the following key depending on laptop/desktop make:

Then:

Insert the usb stick when your pc is turned Off....then start it and boot to that usb stick by tapping the relevant key for your pc/


This may take more than a few attempts. Don't lose patience. Tap gently!, don't break the keys !

Now...pay attention:
When Linux boots, it will be in LIVE/TEST mode. It is NOT fully installed, yet. This test mode will NOT interfere with any windows installed.

You can play around with it, navigate your way all around it, over it in it....knock yourself out!
It will be a bit slower than a fully installed system. ....but you will get a good idea how it reacts with YOUR pc, and your hardware.
Check sound....(youtube(via firefox browser) , Internet, all keys work ? screen resolution, ...all the normal everyday things that usually work for you....test them all. Play a video, etc. connect to facebook etc etc

Please Note: if you reboot or turn your pc off or you get a power failure, Linux will be gone....Kapoof !.....The LIVE version does not survive a reboot. If you want to go again....just repeat the boot procedure to the usb stick and it will be there again (This does not happen in the FULLY installed version)

NOTE: On the desktop, there will be an icon, with the name ""Install Linux Mint"

If you double click that it will start the procedure to FULLY install Mint on your pc.

Dual booting is not something I have much experience of, so I will not comment. (when I started with Linux, I wiped windows completely.....installed Linux straight over the top of windows...Kapoof!....windows gone, Forever)

To completely wipe Windows and Install Linux ONLY.....double click the install Linux Mint icon and follow the prompts. Install media codecs when asked. Password is up to you....Log in automatically is cool..... The password does not need to be complex...Just remember when using Linux, if you cross into the Terminal, (code etc) you will need to type in your password countless times...so an easy to type password makes a great deal of sense. (Got kids etc etc??...introduce a number into the password to increase its safety from prying little fingers.)


I don't wish to underestimate the importance of passwords. If your pc spends its time in a safe environment, then maybe you can afford to use a simplistic password..... but in open ares, coffee shops etc etc etc....keep your password secure

You will come to a screen which will offer your choices about the Installation TYPE you are going to do


1) ..Install Linux Mint alongside Windows Boot Manager... documents, music, and other personal files will be kept. You can choose which operating system you want each time the computer starts up


2) ..Erase disc, and install Linux Mint (ONLY)...Warning: This wil delete all your programs, documents, photos, music and any other files in ALL operating systems. This will automatically partition your drive....just sit back and watch the magic happen.


3) ..Something else. You can create or resize partitions your self, or choose multiple partitions for Linux mint.





(If there is data/music/anything of importance to you on the drive...SAVE IT elsewhere... even if you end up dual booting....save info elsewhere ! (better safe than sorry) An external drive is a must have to save wanted data etc to.





When the Install has finished, you can choose to continue messing around in Test mode....OR.....reboot your PC, take the usb stick OUT when prompted to do that.....


You are now running Linux Mint. FULLY installed.


........... ..........................


1st step?......turn on the firewall.


click on Terminal (it is down on the left side.....hover your mouse over it...one click will open it


Copy and paste this: (accuracy matter...copy and paste ensures no typos with letters or spaces


sudo ufw enable


hit enter


type in your password....hit enter again


Your Firewall is ON


No need for adjustments. (yes it works....the only time you will need to do that again is if you reinstall)


(You really want to check if it is actually on? (copy and paste again, please)


sudo ufw status


See?...I told you !





You can now look shocked......you have just used...code !
 
Wow! Thanks, you've all been a tremendous help. I'll consider buying another SSD. I hadn't even thought of that. But I'll probably end up just installing it over MS OS.
Thanks everyone, again!! Have a great day!!
