MBR here, legacy boot. Every time I added Mint to XP or Win7+10, I used these instructions: https://www.dedoimedo.com/computers/dual_boot.html and https://www.dedoimedo.com/computers/dual-boot-windows-7-ubuntu.html In the instructions, in gparted, and during installation I've never ran into this LBA thingie. Do I need to know it? I tried reading in wikipedia and didn't understand. Could you PLEASE try to describe as you would talking to a 4-yr old?
