I'm trying to install Ubuntu on my external hard-disk. Since I already have some files on that HDD, I created unallocated free space in order to install Linux on there.
I am able to install it, however, I have to make a separate EFI partition - it does not allow me to install without it. But, in the end, I cannot boot Linux from the HDD as it doesn't show in the Boot menu. Or rather, it shows, but upon selecting it goes into Windows Repair Mode.
Do you think such an installation is possible and what could be the problem? As for the EFI, my computer uses Legacy BIOS but I cannot seem to install without it.
