Installed CachyOS over boot drive

I was told to put the results of a command that shows my drives info. I hope this is the right place:

TY for any help you give.

I used to boot from the 970 so I hope it still has the boot files. The linux install is on the 850 which had the boot files. The other drive is my backup drive.

The only thing that seems to be left from an ex Windows system on this drive is only a 1M Microsoft reserved partition. Not sure how you installed your system but if there was any Windows system on this disk before, now it seems to be gone.

It’d be helpful if you shared what sort of help you are looking for. Assuming it boots it looks like you’ve successfully migrated to cachy.

tbe windows install is here

Only 850 and wdc have efi, 750 have not.

If you have windows installation USB, disconnect any other drives except 750 and try to recover/fix windows.

If you do it with other drives connected, with your knowledge, you might end up with all drives deleted.
