Hello everyone! I’m pretty new to OpenSUSE and I’m very much enjoying Tumbleweed.
My problem is that I installed Tumbleweed on my desktop and now I can only boot into Linux. The Grub doesn’t show a Windows 10 option.
Windows’ files are still visible in Dolphin, YasT boot manager has “probe foreign OS” enabled. I tried os-prober and it returned nothing.
I’m a bit worried that I made a mix of Legacy and UEFI.
Thanks in advance.
Does
ls -l /boot/efi/EFI
show a Microsoft entry?
Nope.
ls: cannot access '/boot/efi/EFI': No such file or directory
Then Tumbleweed was installed with legacy boot.
Darn. How would I go about fixing this? Should I reinstall Tumbleweed?
Let’s take a look at the partitioning:
sudo fdisk -l

I don’t know if that will work because I’ve never had to do that before.
First you have to figure out the UUID of /dev/sda2.
sudo blkid /dev/sda2
/dev/sda2: UUID="BE02-0DD3" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="d890d03e-c2d7-4a8b-99f7-fdd953827da6"
Now add this line to
/etc/fstab
UUID=BE02-0DD3 /boot/efi vfat utf8 0 2
Note that Windows does not show up in Linux if fast boot is turned on.
You have to add the line within /etc/fstab an then to save as /etc/fstab again.
I just rebooted and disabled fast boot, same result.
Okay I did it!
Then open YaST Bootloader and choose
Grub2 for EFI → OK.
Try
sudo mount -a
previously
mount: /boot/efi: mount point does not exist.
dmesg(1) may have more information after failed mount system call.
Please show the output of
cat /etc/fstab
