I upgraded my system from Fedora 29 to Fedora 30, then to Fedora 31. Although the OS version was Fedora 31, the kernel was still listed as fc29. I used the recommended script to switch to blcs and grub2.
After a kernel update today (vmlinuz-5.4.19-200.fc31_x86_64), when I boot the system it goes to the grub promp with Grub 1.99 at the top.
I have tried to boot from the grub menu with
set root=(hd0,gpt1) linux (hdo,gpt1)/boot/vmlinuz-5.4.19-200.fc31_x86_64 boot
But, the system won’t boot and I get an error:
not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Is there way to switch to grub2 from the grub1.99 menu?
