Hi,

I want to boot with a customized iPXE iso boot file from my GRUB2 menu. My system is running CentOS-7, with /boot formated as XFS filesystem. After copying my iPXE.iso into /boot, I have created a custom GRUB2 file in /etc/grub.d/40_custom like this:

menuentry “iPXE” {
set isofile=”/ipxe.iso”
loopback loop (hd0,1)$isofile
linux16 (loop)/ipxe.lkrn
}

After regenerating grub2.cfg with “grub2-mkconfig -o /etc/grub2.cfg , I have rebooted my system, I have chosen “iPXE” entry, but system doesn’t boot. I receive this error:
error: file ‘/ipxe.iso’ not found. Starting /ipxe.iso… error: no server is specified. Press any key to continue…

However, in another similar system that runs /boot in EXT4 filesystem, that ISO file boots perfectly with the same configuration, so it seems the problem is with XFS.

Could you help me?

Thanks.
