[Solved, sort of] Dualbooting, windows wont work when I switch from RST to AHCI? Alternative methods? - eviltoast

Hello, I’m trying to install ubuntu alongside windows 10 which I need for school.

I’ve tried two methods to get windows to use AHCI: 1) switch to safe mode, choose AHCI in the BIOS, log on to windows then turn safe mode off. 2) use the registry editor to get the AHCI drivers on, then choose AHCI in the BIOS.

In both cases windows fails to startup and thinks the hard disk is messed up. Are there any alternative methods? Anything I couldve gotten wrong? Unable to find leads so far.

I will next be trying to update some drivers, maybe that will work, but would love some guidance until I get back to trying.

EDIT: I wasn’t able to figure out how to get my existing windows installation to work with AHCI. I also wasnt able to use a windows live usb to fix my isntallation. I had two partitions and ended up installing windows on the partition I had freed up for ubuntu, moving my files to it, then installing ubuntu on the partition windows initially was on.

I have no idea whats wrong with my computer because that wasnt all the trouble I faced lol, but now am happy I have ubuntu working.
