Tries to boot Redo Rescue ISO in a Multiboot USB thumb drive.

[Ricardo J. Pinheiro]

I prepared a USB thumb drive with almost every software tool that I found interesting and useful, so I can boot a PC and do every maintenance task I need. And I'm an old Redo Rescue user, so I decided to add Redo's ISO to my thumb drive's collection.

I'm using a custom grub.cfg file, so I can choose each tool will be run at boot. Almost all tools runs smoothly (even Windows 10), but I can't boot Redo Rescue - there are always a message telling me that it cannot boot, and the initramfs prompt can be seen.

Here goes my menuentry for Redo Rescue:

menuentry "Redo Rescue: Backup and Recovery"{
set disklabel='MANUTENCAO'
set root='(hd0,1)'
set devroot="/dev/disk/by-label/${disklabel}"
set gfxpayload=text
set isofile_abspath="/isos/Imagem/redorescue-4.0.0.iso"
set isofile_devpath="${devroot}${isofile_abspath}"
insmod part_gpt
insmod ext2
loopback loop "(${root})${isofile_abspath}"
linux '(loop)/vmlinuz' boot=live noprompt nocomponents setkmap=us
initrd '(loop)/initrd'
}

I tried almost everything, but I was unsuccessful. Any ideas would be appreciated.

Thanks in advance,
Ricardo.
