I know how to manually boot from a GRUB menu, I have a number of custom entries in /etc/grub.d/40_custom so have an idea as to what is needed to load an O/S but far from an expert Cool

I have an older external drive that to date I have switched to legacy BIOS to use but looking at the GRUB entries they look the same or similar to a manual boot from UEFI

I did try a manual boot of the legacy system but got some message telling me the kernel was too old (Apologies, didn't note it properly) whereas it boots fine if I switch to legacy.
