I had a dual boot system with windows and manjaro and successfully installed grub with os-prober enabled. This is what my lsblk output USED to look like:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 1.8T 0 disk
├─sda1 8:1 0 16M 0 part
└─sda2 8:2 0 1.8T 0 part
nvme0n1 259:0 0 465.8G 0 disk
├─nvme0n1p1 259:2 0 512M 0 part /boot/efi
└─nvme0n1p2 259:3 0 465.3G 0 part /
nvme1n1 259:1 0 465.8G 0 disk
├─nvme1n1p1 259:4 0 529M 0 part
├─nvme1n1p2 259:5 0 99M 0 part
├─nvme1n1p3 259:6 0 16M 0 part
└─nvme1n1p4 259:7 0 465.1G 0 part
Everything worked great.
sda is just a big empty data drive.
nvme0n1 is my manjaro drive (where root and boot are installed)
nvme1n1 is the windows disk drive.
Suddenly I was no longer able to boot into windows as grub said it couldn’t find nvme1n1. I haven’t removed the internal hard drive windows is installed on. When I now run lsblk I get the following output:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS

It is no longer there. Any idea how I can get this back?
Thanks
