How to mount/extract a .img ?


So, I got debian live usb .img
I don't wanna dd my usb as I already know what needs to be done to install it myself

But, how do I mount the .img file?
I tried mount -o loop name.img
and it says define fs type?
so, mount -o loop -t ext2 name.img or what?

Is it a CD image? If so, try -t iso9660
You will need to specify the fstype, so the best thing to do is find out what that is.

Linus,

The second post in this thread suggests a possibility:

See what you think.

OK
here's what "file debian.img" says

Code:
root@PartedMagic:/media/hda6/home/bz/Desktop# file debian.img
debian.img: x86 boot sector; partition 1: ID=0x83, active, starthead 0, startsector 1, 946175 sectors, code offset 0x31
that's wild huh?

here's mount -t ext2 -o loop debian.img mnt

Code:
root@PartedMagic:/media/hda6/home/bz/Desktop# mount -t ext2 -o loop debian.img mnt
mount: wrong fs type, bad option, bad superblock on /dev/loop3,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
what else can I try?
mounting it according to offset?
I'm stuck...

there's a few dindows apps that can do this
it must be doable in linux too...

"'Cause I have 2 partitions on usb, one live-rw for remastering/persistency
'cause I already know what dd'ing it does: it labels it DEBIAN_LIVE,installs syslinux, and
copies debian live to usb"
and, it also makes my 2gb usb into a 300+mb usb??!

Did you try the first command from the link?

Code:
mount -o loop ./<filename>.img /mnt/<some folder>

see it as a block device with a partition inside

so you need to make a device file and mount it the usual way

How?
I tried mount /dev/debian.img /mnt/debian
Quote:
mount: /dev/debian.img is not a block device
what should I do?

mount: you must specify the filesystem type
I tried that too

Since the image includes the MBR and partition table you will need to use the offset option.
Using the dd command will recreate the image byte for byte. The drive will now appear to be the same size as the image which as you have indicated is 300mb.
