Clonezilla Could not stat device /dev/sda
I try to install 24 computers at the same time with Linux 12.04 Desktop. PXE works but is on unicast basis and I need something quicker and spare my io. I found clonezilla eventhough I had to fix a few bugs (I guess because of 12.04) i got it to work. The client boots with pxe and I need to make a image of the client that can be distributed to all others. I've attached a screenshot with the error message. It states the following:

Selecting device [sda1] found!
Selecting device [sda2] found!
Selecting device [sda5] found!
Getting /dev/sda1 info
Getting /dev/sda2 info
Getting /dev/sda5 info
Checking the integrity of partition table in the disk /dev/sda...
The partition table in this disk is illegal/invalid: /dev/sda
It's not supported by parted. Parted is used in clonezilla to parse the filesystem in the partition table. This partition table is detected as WRONG by parted!
The error messages from parted are:
#####################
Error: Could not stat device /dev/sda - no such file or directory.
####################

Offcourse I've checked the partitions and they are indeed named sda1 and 2. It doesnt matter if i try to image the entire disk or just the two partitions

Some one asked me to post the following, hope it helps.

Still no one? I've discoverd that via the live CD everything works perfect. I can make and restore the images. However via PXE I can neither make or restore the images.
The error message with a image made from live CD and restored via PXE is the following:

sfdisk: Fatal error: cannot find /dev/sda
This is done by sfdisk --force /dev/sda < /home/partimag/2012-05-07-11-img2/sda-pt.sf
