Hi,
I'm trying to mount a partition of dd imagen on /dev/loop but it says me that is not ext4 partition. The code is:
Code:

mount: wrong fs type, bad option, bad superblock on /dev/loop1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
