background: I had 2 installs of windows on 2 separate drives (which were also separate from bazzite). the drive i just formatted was the 1st OS install after my PC basically imploded so i could recover the data from what was my original C drive and then reformat and reinstall windows on the drive i wanted it to be one (the 2nd and primarily used OS install).
Im in the process of converting most of my storage to btrfs and I just reformatted one of my drives after clearing out everything but my 1st OS install. after doing so I went to restart into my 2nd (main) windows to check on something, but grub is giving my some kind of boot loader/efi failure/missing issue. I'm assuming that nuking the 1st install messing something up, but I have no clue how to actually fix this issue.
assistance would be greatly appreciated, thank you in advance
add-on: the only real thing i found on google said to regen grub, but that just took away OS selection entirely. pretty much everything else ive found is what happens in windows tries to take over bazzite.
