Experimenting with another (non-Windows) distro installed on a separate HD. It boots from that drive when set in the BIOS. But Yast2 does not recognize there is a bootable distro there. How do I manually add it to the grub2 configuration?
Wondering if a missing or incorrect MBR boot record could cause a boot fail…
Of course we should all know that a Secure Boot requires a signature,
But I don’t remember running into any disk fails known to be specific to an MBR signature, although I’ve had occasions when a MBR mysteriously went bad and had to be re-initialized (maybe some kind of signature problem? Never checked).
