Tried to install Gentoo and now I cant boot into my CachyOS drive

After spending 8 hours attempting to install Gentoo I finally gave up after multiple kernel panics, when I tried to boot back into CachyOS my pc would just boot into BIOS again. I’ve only been able to boot into my Gentoo LiveGUI USB. I checked lsblk and only sda1 and sda2 where present and I think it has something to do with that. I’d really like to not have to wipe my drive to reinstall CachyOS

my apologies if the CachyOS forums aren’t the correct place for this

gentoo on different drive?

used a different bootloader?

if your cachy partition still exists theres cachy-chroot:
