I was following up with installation CD of Open Suse 11.0
the first step is download the OpenSUSE 11.3 dvd ( 11.0 is past it's end of life )
then download and burn to cd "SystemRescueCD "
both of these can be done on a windows OS
run the systemrescue cd and see what it shows
but mostlikely you will need to reinstall it ,if it is not just a messed up table
I formatted it for some purpose and could not formated it instantly due to some reason,
it is mostlikely lost but if you only deleated the partition and did not fully reformat it. It might be recoverable ( a deleted partition table
but i would not bet on that .
