I still for the life of me can’t figure out what’s so great about secure boot and tpm. All it’s ever done for me is prevent me from booting a legitimate OS, or a bootable flash drive with iso images on it (like ventoy). It’s also pretty good at giving me a headache trying to figure out how the keys work and how to register them.
I just turn them both off and live in ignorant bliss.
I’ve been a dual / triple / god knows how many OS booted since the 90’s.
Windows has gotten into bad habits lately - it’s not staying in its lane. Meaning it hasn’t respected other boot partitions for a long time, and recently there seems to be a lot of people having problems with windows nuking their linux installs.
My strong recommendation is to buy a second hard drive if you dual boot. Then windows can be “over there” - I’ve never had a problem dedicating ssds to the OS. My second recommendation is to do this now, why wait until you’re forced into something? You’ve got a year to learn Linux and get comfortable with it.
