I'm not sure there is an "out of memory error".

What I see is :

So we have 'Unable to mount root fs'  and "unknown-block"

Please explain what the idea is behind

| label linux0
| menu label MyFedora13 (default)
|   kernel vmlinuz0
| APPEND rootflags=loop initrd=initrd0.img root=live:/FC13.iso
| rootfstype=iso9660 rw liveimg quiet selinux=0 rhgb rd_NO_LUKS rd_NO_MD
| noiswmd blacklist nouveau

especial the idea about 'root=' and 'rootfstype='
