I recently upgraded my computer and reused my old SSD from a previous build. Now, my new system—a 5080 with an R7 9800X3D—won't boot past a black screen with a blinking underscore in the corner. I initially had a Dell XPS system with a 3060 TI and Core i7, and now I'm using a different setup with CachyOS. I've tried adding `systemd.unit=multi-user.target` to the grub entry, which gets me to a terminal, but I can't get to SDDM. I'm not sure if this is a kernel issue or something with the GPU drivers. Any help would be appreciated! I'm currently backing up everything to an external drive in case I have to wipe and reinstall the OS.

You might want to boot from a live CD and chroot into your system. Once there, try removing the Intel microcode if you don’t need it and install the AMD microcode instead. Don't forget to rebuild the initramfs afterwards.
Have you thought about switching the monitor to another port, like the motherboard's I/O? That sometimes helps get past initial boot issues.
If you're seeing a static underscore, you might need to try the `nomodeset` boot option to see if that gets you to a failsafe graphics mode. Just a tip!
Are you trying to reuse your old OS installation or doing a fresh install? If you have a second computer, you can plug the SSD into it to check if it’s working properly. Just a thought to guide further advice.
Honestly, for a smoother experience, it might be easier to just back everything up and do a fresh install of the OS. Trying to reuse an old install can lead to all sorts of headaches.
Got it! I thought it wouldn't be this complicated since the setup isn't that different, but I'll give chrooting a shot.
