when i type:

i get

mount: you must specify the filesystem type

what do this mean?

It's looking for a .iso file name.

sudo mount -o loop /win/ubuntu/disks/root.iso /vdisk

should work (assuming root.iso is in fact an ISO file format, and the mount point /vdisk exists).

mount: you must specify the filesystem type
what do this mean?

From the man pages ("man mount" in a konsole)

THE LOOP DEVICE
One further possible type is a mount via the loop device. For example, the command

mount /tmp/fdimage /mnt -t vfat -o loop=/dev/loop3

will set up the loop device /dev/loop3 to correspond to the file /tmp/fdimage, and then mount this device on /mnt.

This type of mount knows about four options, namely loop, offset, sizelimit and encryption, that are really options to losetup(8). If the mount requires a passphrase, you will be prompted for one unless you specify a file descriptor to read from instead with the --pass-fd option. (These options can be used in addition to those specific to the filesystem type.)

If no explicit loop device is mentioned (but just an option `-o loop' is given), then mount will
try to find some unused loop device and use that.

Since Linux 2.6.25 is supported auto-destruction of loop devices and then any loop device allocated by mount will be freed by umount independently on /etc/mtab.

You can also free a loop device by hand, using `losetup -d' or `umount -d`.

In your case the command would be

mount /win/ubuntu/disks/root.disk /vdisk -t iso9660 -o loop=/dev/loop0

assuming, as Snowhog said, that root.disk is really an iso image. Normally, one would want to have an extension of ".iso" as part of an iso9660 image file name. BTW, in the /dev sub-directory there are eight loop devices, loop0 through loop7. You can use any one of them. Loop0 is not sacred.

Most of the mount man pages are given to describing the various kinds of device types that "mount" and mount, and what their syntax parameters are. Also, the "unmount" command is "umount", not "unmount".

if this was going to work you would have first had to mount your windows partition under /win and made the DIR /vdisk to mount it to................it looks like you just coped it frome the WubiGuide...hear

https://wiki.ubuntu.com/WubiGuide#Wh...%20bootloader?

find your line in thare and then read the section.

if you did do all that then got the error try adding -t iso9660 right after loop so it looks like this

sudo mount -o loop -t iso9660 /win/ubuntu/disks/root.disk /vdisk

provided of corse that the root.disk is in fact a iso? and you had mounted windows under /win and made the mount point /vdisk

when i do:

mount /win/ubuntu/disks/root.disk /vdisk -t iso9660 -o loop=/dev/loop0

i get: mount: stolen loop=/dev/loop0



when i do:

mount -o loop -t iso9660 /win/ubuntu/disks/root.disk /vdisk

i get: mount: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program........................

Re: sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk

The first error suggests that loop0 was in use at the time. I.E., you had tried to create a loop device and it succeeded. Not knowing it had succeeded (no return msg usually means success) you tried it again.

Use
sudo losetup -f

to find the first unused loop device.

The second error suggests that you found an unused loop device but your image is corrupt.

What does what Dibl suggested do?:

mount -o loop /win/ubuntu/disks/root.disk /vdisk
