My current system only has W10 on it. But what I did with my older PC was to remove the internal drives, then install a hard drive tray and hooked it to the SATA0 port. I also have a DVD drive in it hooked up to SATA1. This allows me to swap out the SSD/HDD when I want to play around with Linux, but still keep the old W7/10 drive alive "just in case."
Doing this allowed me to play around with Mint 21.3 until I could get it running and up to speed. I need to purchase a newer video card though cuz the old GT 740 isn't supported well by Linux and could fritz out on me again. But once I get it running the way I want then I'll look at installing Virtualbox and seeing how well Windows 10 plays within it. I was told I could import my current W10 install so if I can make that work it'll open up more possibilities for me.
If you get it to import your current os win 10, I’d be interested in how it went. I’ll have to look into that. Didn’t realize it was possibility. Swapping out drives is another easy way to do things too. I kept the side off my system for awhile and would do that when I was trying a bunch of Linux flavors. Had a bunch of old drives I installed various Linux’s to. Didn’t want to mess with dual boot at that point. I finally,settled on mint cinnamon. Been my main os for years now. Still have to go into windows from time to time, so I keep 10 and 11 on separate second drive.
Wish i had gotten into computers at younger age though... so much. To them. I forget probably 80% of things I look up to do like dual booting. My next project I think will be winboat- if I can get that running and run my windows programs inside Linux, that’d be the better option I think.
