I have tried that MANY times at this point.  Nothing grub related wants to work for me.  Also, as far as I know, it should be "root (hd0,0)" and then "setup (hd0)".  However, I have tried both ;-)  I get "Error 21: Selected disk does not exist" when I do  the grub commands.  However, as i stated in my previous post, I can mount /dev/sda1(which is grub's hd0,0) and look at the contents just fine. 
For thos wondering, I generally do not install with one big partition, however, with the problems I have been facing I decided to simplify the installation to make it as managable as possible until I can figure out the problem.

In order to fix GRUB, boot to a Live CD, pull up a terminal and "grub". At the grub prompt "root (hd0)" and "setup (hd0)" should write GRUB to the mbr, using the /boot/grub/menu.lst that's on (hd0,0) (that's /dev/sda, in your case).

Notice this does not fix the imaging issue, it just fixes a broken GRUB install. Likely once you have GRUB written to the MBR correctly, the imaging issue will disappear for that particular (client) machine.

HTH,

Subject: [Sisuite-users] GRUB issues


After upgrading to the latest stable Debian/Ubuntu package, I appear to have Systemimager working with one minor exception.
I can pull an image from a golden-client.  I can push an image out to a new client.  However, when I try to reboot the new client, I either just get the word "GRUB" or the message "no operating system found".  I booted the newly imaged client with an install disk and mounted the partition where the OS was installed(/dev/sda1).  It mounts fine and all of the files appear to be there and in their correct places.  For some reason the MBR seems to get clobbered during the imaging process.  Is this a known issue?  I have read some vague references to it on the list.  I tried fixing the problem by running grub from the install disk and I am still getting no where.  I know which disk/partition I need to specify in grub because I can mount that partition and look at  it.  From the  install disk i do the following.

sudo mkdir /mnt/root
sudo mount /dev/sda1 /mnt/root

When I  do an ls everything looks fine.
Does anyone have any idea how to either 1) fix this via post-installation scripts or 2) fix it in the imaging process so my clients will boot?
Thanks,
Jason
