Can't install Bootloader/Device not Found

I recently got a new 2TB SSD and imaged my old one onto it. I had it set to dual boot with Windows 10 using Grub. When I plugged the new drive in I would get an error saying “filesystem not found” and a rescue console. Using the old drive I was able to restore the Windows bootloader and boot to Windows. Now I’m trying to get back to the Linux bootloader so I can dual boot again. I downloaded the latest install disk for 15.6 Leap(The original system was at 15.3) and created a USB Installer for it. When I booted from the install disk I selected the ‘Boot to Linux’ option and was able to log into my Linux partition.

However, this is where things went south. I tried to install the Bootloader through Yast2 and got the following message:

Probing file system with UUID XXXXXXXXX failed
Unexpected situation found in the system.

Continue despite the issue?

When I click to see more details:

device not found, name:/dev/sda4

If I click to Continue:

YaST cannot configure the bootloader because it failed to find the root file system.

The same error occurs if i open up Partitioning, but if I open up the Disks application, it shows all the partitions on the drive. Clearly /dev/sda4 DOES exist as it is the partition that Linux is running from.

Searching the forums I did find another thread with the same issue which referenced the following bug report:

I tried the fix listed in there, invoking “LIBSTORAGE_BTRFS_SNAPSHOT_RELATIONS=no yast2 bootloader” but that still had the same result.

I tried to upgrade the system using the installer USB, but had the same issue. After setting up all the configuration options it gave me the same device not found error, so I booted back into the system and did the install in place using zypper. Everything seems to have gone alright there and it looks like I am now running 15.6 Leap. I still have to use the USB to boot into the system though.

Aside from getting rid of the current Linux install and reinstalling from scratch, does anyone have any ideas of what I can do to fix it?

What exactly does it mean?

Output of

cat /etc/fstab
findmnt --real -u -o +uuid,partuuid
fdisk -l
lsblk -f -o +partuuid
efibootmgr -v
cat /etc/default/grub_installdevice

could be interesting. As preformatted text or uploaded to

I used a disc copying program (in this case Arconis) to create an exact image of the original hard drive which was then copied onto this one. I’ve done it many times before with Linux/Windows dual boot drives and never had an issue previously

cat /etc/default/grub_installdevice


Your /etc/fstab does not have entry for /boot/efi which implies that your system has been setup to boot in legacy BIOS mode. When you boot from USB you need to select legacy boot (CSM or whatever it is called in your BIOS).

This refers to your old drive. When you call YaST Bootloader it should suggest to reinitialize bootloader configuration. Does it?

Also check for such /dev/disk/by-id/... references in /etc/default/grub (could be setup for resume device). Or just show this file:

grep -Ev '^$|^#' /etc/default/grub

I selected Legacy boot for the USB, and still have the same issue.

grep -Ev ‘^$|^#’ /etc/default/grub:

GRUB_CMDLINE_LINUX_DEFAULT="splash=silent mitigations=auto quiet"

No, when I call the bootloader program through Yast/Yast2 it stops after “Loading bootloader settings” and gives me the error above about missing sda4.

Bit of an update.

Using “update-bootloader” I was able to restore the bootloader so I don’t have to use the USB Installer to load into Linux anymore. The Grub bootloader is back and I can pick between OpenSuse and Windows with no issues.

However the dev/sda4 not being found issue is still persisting. I cannot load the bootloader module from Yast or Yast2, or open the Partitioner module. In both cases the error persists.

Clearly this is due to the reference to the old drive, but how do we fix that?
