Re: GRUB is reported to usually fail.
This is misleading at best.
OpenBSD can easily and reliably be booted from Grub installed on a
Debian, Debian Derivative or Arch Linux using Grub installed per the
wiki.
Essentially, the EFI partition is used in common with both Operating
systems.
The most time efficient way to install to a single disk is to install
Linux first and manually partition:
Partition1 = EFI
Partition2 = Linux /
Partition3 = Linux swap
Partition4 = allocated to OpenBSD
After the linux install, use the native partition manager in Linux,
fdisk or gparted, to set Partition4 to type OpenBSD(data).
Install OpenBSD to the OpenBSD area.
Next boot back into Linux and download the OpenBSD "BOOTX64.EFi" file
and install to /boot/efi/.
Edit /etc/grub.d/40_custom to:
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply
type the
# menu entries you want to add after this comment. Be careful not to
change
# the 'exec tail' line above.
menuentry 'OpenBSD 7.8' {
chainloader (hd0,gpt1)/BOOTX64.EFI
}
and run /sbin/update-grub.
Your next boot should have a Grub menu entry for OpenBSD 7.8.
Fedora/RedHat uses a conflicting /boot/efi/BOOTX64.EFI
I'll work with the FAQ maintainers to correct.
