SBS has died, looking for a bit of help!

Hi all,

Here's the scoop.

I have SBS 2003 installed on a Dell PE 2600.  Today, I tried to upgrade the disks from basic to dynamic as I have done many times before.  When I attempted to do so, it stated an error to the like of::::::  Cannot upgrade disk?  Then I bounced the server to try it again and it blue screened and reboot itself.  It is now stuck in a loop of the same and I cant get into the OS.  On boot it says that 1 logical drive has been detected but no physical drives?  I should also mention the C drive, at time of reboot, only had 308mb free space.  

I have tried the following:

Last known good config
Boot into safe mode.
Checked the disks in utility mode (both are online and healthy)

I am debating to try a repair reinstall of SBS but have never done one.  The main problem is these guys had no  backup of the server, so if I can get the data back I think it would be a miracle at this point.

Any help would be great.

Thanks,

Paul
