SBS2011 Crash Backed Up with BEX2010R3

Hello there

I have a mysterious problem, that one server after a reboot, would come again and again into the system recovery console. Its an HP Proliant ML370 G7.

I restored an Image wich was made with BESR2010. But same issue.

Now i'm thinking to make a reinstallation of SBS2011 and after the installation, i would boot F8 and select directory services restore (Verzeichnisdienstwiederherstellung). And then, make a Restore of the SBS2011 wich was made with BackupExec 2010R3.

Is this way supportet and working?
