- get your perferred iso
- do a checksum if available (basecally check the signature of the original file with yours, the checksum often is available on the website)
- get beleana etcher or i think rufus can also do linux isos but i’n not shure
- get an usb stick with min 4gb
- flash iso onto usb stick
- stick usb stick into perferred pc
- boot onot that usb stick (for my motherboard it’s F10 but that can be different for you)
- boot into the live iso and the installer should pop up
- read the instructions of the installer carefully
- you are done enjoy your new os
although i would recommend playing around with different distros in a vm to see waht you like and if all your needed software is available
on lemmy are you shure ?
