I can't remember exactly what I did, but I think I copied an F31 install
onto an existing F31 install on a hard drive that had Windows 10 on
it. I did this in early 2020. Didn't keep notes. :(
Now I have a hard drive that will boot Windows 10 fine, via the Windows
10 Boot Manager.
When I go into the BIOS manager, it shows 2 boot options: Windows 10 via
the Windows 10 Boot Manager and the hard drive device itself.
If I choose Windows 10, Win 10 boots fine. :(
If I choose the hard drive device itself, the BIOS says to insert a
valid boot device.
When I look at the hard drive with GParted, I see this:
Samsung SSD 850 EVO mSATA 500 GB with:
/dev/sdb1 ntfs Recovery (Windows)
/dev/sdb2 fat32 EFI System Partition Has a boot flag
/dev/sdb3 unknown type Microsoft Reserved Partition
/dev/sdb4 ntfs Basic data partition
/dev/sdb5 ext4 <--- this is the boot partition, has the boot stuff
on it. Has a boot flag.
/dev/sdb6 lvm2 pv fedora
A fedora "device" which has 3 partitions:
/dev/fedora/home ext4 the home directory
/dev/fedora/root ext4
/dev/fedora/swap linuxswap
I used a live USB version to facilitate the copy. I suspect that the
live boot got installed (thus the FAT32 partition) instead of the real
boot partition, which is /dev/sda5 right now.
The FAT32 partition is the EFI boot partition. Did this disk ever work
with Fedora? I expect that you didn't copy the Fedora files that were
in that partition on wherever you copied it from. It's tricky to fix
that. Do you still have whatever drive you copied it from originally?
