Hi
After I made a blunder in erasing the MBR and some additional sectors at
the begining of my hdd, I rewrote my MBR with both testdisk and dd.
However, I was unable to properly repair /dev/sda1 which remained in a
faulty state.
I'm used to use "loopback", "linux", "initrd" and "boot" to boot from
iso files when I want to install or reinstall a GNU/Linux distribution,
and "search" to locate the device where my iso file sits. When I ran
grub to boot in such a way, with my faulty /dev/sda1 partition, grub
sent me a
"No such device" message, naming my iso file. After I zeroed the first
MBR entry, grub successfully booted from my iso file, whithout me
modifying anything else.
It turns out that this faulty partition also prevented a USB-generated
USB key to boot the PC.
