Betreff: Re: tried to install F30 and F31 on 2 separate Partition on 1
external disk
Each distro creates its own directory under /boot/efi/EFI, so I have
/boot/efi/EFI/fedora, /boot/efi/EFI/manjaro. /boot/efi/EFI/ubuntu.
And in each distro's directory, there's a set of the distro's own grub
files, including grub.cfg, that will bring up a normal grub menu let me
boot any of my installations. Selecting an individual distro's
/boot/efi/EFI has to be done in the boot setup screen or the 'System
setup' entry in Fedora's grub menu
Hi
How do You select in using "system setup"? I can not select a partition
of an internal or external disk (Acer laptop, not very old). I can only
select DVD, several usb devices, harddisk and so on, but not a special
partition of a device.
With UEFI, the boot loaders are all stored on the EFI partition which
Fedora mounts at /boot/efi. There is no partition selection, although
you can select which hard drive(s) it will look at. In order to be able
to select one of the boot loaders, an entry has to be created for it in
the boot table. "efibootmgr" is the tool for that. Then, depending on
the BIOS, you can adjust the order or those entries. I have come across
a couple of laptops that insisted that Windows had to be the first one
and those were quite difficult to setup to boot Fedora.
