Subject: Re: multiboot 2 HD
Each of my three drives is bootable has its own EFI partition and multiple Linux installations. Each /EFI/fedora/grub.cfg file is manually maintained as it gets overwritten when I update grub, and each Linux installation has its own /boot/grub2/grub.cfg.
The /EFI/fedora/grub.cfg files are all basically the same, with entries that chainload each installation's /boot/grub2/grub.cfg file along with entries to chainload each drive's /EFI/fedora/grub.cfg.
I guess that it is fine for a UEFI machine.
But for an non UEFI machine?
On sda I have a /boot 1
the grub.cfg /boot/grub2 (sda2) generated by fedora 1 is fine
On sdb I have another /boot 2
the grub.cfg (sdb5) generated by fedora 2 is also fine
(of course they are different files)
But the bizarre thing is that the bootloader uses /boot 2
Why?
The last one installed will be the one used. You need to run grub
install from the first one again if you want that to be the default.
This is what I would have thought
However,
grub2-install /dev/sda
Provides an error.
What do you mean by grub install ?
That's what I mean. What's the error?
When you were installing the second one, I think you could have
installed the bootloader to the second disk that you were installing to.
