After upgrade BIOS, the Rocky linux always show blue screen with “boot option restoration”.
it must need manual select. else the OS will restart again and again with default value “reset system”.
A bit of googling indicates that this is (or may be) something to do with uefi bios and Windows Boot Manager.
Are you dual-booting with Windows and using Windows Boot Manager? If so, then you may have to fix something under the /EFI path in Windows Boot Manager.
