Google is useless for this, so hopefully the Fediverse can help.
I have a PC with Windows 11 on one SSD and I want to install #linux on another SSD. I don't want to touch the current primary SSD at all, just boot from USB, install Linux, set that new SSD as primary boot partition in the #UEFI #BIOS and from then on have the Linux boot manager show up and let me choose which OS I want to boot. I use Linux, but haven't set up #DualBoot in literal decades. Any tips/guides for this specific case?
