Hello I state that I do not know linux very well, we understand something cmq

Let me explain my problem, I have a SLES 9 server physical raid through the vmware converter I have virtualized creating the virtual machine, the problem is that at startup crashes
while trying to load partitions, recognizes all disks as sda 1 / sda2 / sda3 etc etc.
trying to fix with an upgrade to SLES 10 gives me the following error: the root partition is mounted with dev/sda2 but is registered as dev/rd/c0d0p2

Does anyone have any idea on how to fix it?
