I'm trying to boot Buster installer from a USB by using Grub's loopback
device.
I already installed grub in the USB and put Buster ISO in its data
partition.
I read this
https://wiki.debian.org/Installation+Archive+USBStick#Using_GRUB.27s_Loopback_Facility
so I downloaded both hd-media kernel and initrd from here
http://ftp.debian.org/debian/dists/stable/main/installer-amd64/current/images/hd-media/
and put them in same directory as ISO, renaming them as "DebianVmlinuz"
and "debianGtkInitrd" respectively.
This is my grub.cfg config:
iso_path=/boot/iso/debian-10.1.0-amd64-xfce-CD-1.iso
export iso_path
search --set=root --file "$iso_path"
loopback loop "$iso_path"
menuentry "Graphical install" {
bootoptions="findiso=$iso_path desktop=xfce vga=788 --- quiet"
linux /boot/iso/DebianVmlinuz $bootoptions
initrd /boot/iso/debianGtkInitrd.gz
}
So booting from the USB works; the installer starts. But after selecting
languages it searches for the installer ISO, but always fails to find
it. I get "Debian was unable to find an ISO installer image". Even if I
tell it to browse the specific partition where ISO is it just fails with
same error.
I also tried loading hd-media initrd in conjunction with Buster ISO's
vmlinuz kernel, by specifying the loop device instead. Installer starts
as well but everything else the same: same error.
Can someone help please with this issue?
Thanks beforehand.
