.IMG file help!!!
I've been trying to create an IMG file for the past week with no success. I've tried using:

Code:
dd if=/dev/zero of=myimage.img bs=512 count=2880
mke2fs myimage.img
mkdir /media/mount_point
mount -o loop myimage.img /media/mount_point
cp -aR <file> /media/mount_point
umount /media/mount_point

and it completes without errors or anything of the sort, but then when I mount "myimage.img" nothing is in it. Smilie
So can anyone tell me what I'm doing wrong or what I could possibly do to create an IMG file on ubuntu?

thanks in advance

Please explain exactly what you are trying to do. What do you plan to do which the image file once you have created it?

I plan to boot from it using "qemu". I'm actually following the steps given here to generate the image but these don't work for me either. I'm assuming it's because I don't have a floppy drive.

Your problem has nothing to do with not having a floppy drive.

What operating system and distribution are you actually using to create the image.

Are you literally typing:
Code:
cp -aR <file> /media/mount_point

or is <file> replaced with something else?

If so what is the actual command you are typing?

I'm running ubuntu and I'm replacing <file> with the files I want to copy. The actual command is:

cp -aR /home/neur0n/L4/* /media/mount_point

it works absolutely fine for me. I suspect your file actually isn't being mounted.

Check that mount works right. When it's mounted you should be able to run df -h and see a line like
Code:
$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda5             9.9G  653M  8.8G   7% /
udev                   10M  376K  9.7M   4% /dev
/dev/sda6              15G  8.3G  5.9G  59% /usr
/dev/sda7              15G  311M   14G   3% /var
/dev/sda9             233G   39G  183G  18% /home
shm                   1.9G     0  1.9G   0% /dev/shm
/dev/loop0            1.4M   20K  1.3M   2% /home/monttyle/test/media
$

If Corona is correct in his theory, the copied files should exist at /media/mount_point and be visible when no file system is mounted on /media/mount_point.
