I followed Software installer in upgrading from Fedora 36 to Fedora 37. After install and reboot I end up in GRUB shell.
I try to boot again using this.
The result is the same for all available kernel versions including rescue.
Error message in dracut shell:
[FAILED] Failed to start initrd-switch-root.service
:/root# systemctl status initrd-switch-root.service
Failed to switch root: Specified switch root path ‘/sysroot’ does not seem to be an OS tree. os-release file is missing.
In journalctl maybe interesting errors:
EFI loader partition unknown, exiting.
(The boot loader did not set EFI variable LoaderDevicePartUUID.)
How to complete boot?
