<<No operating system installed or parttion corrupted>>
That means that either the hard drive appears to be damaged...or there is a problem with the file structure on the partition, which prevents the system from functioning properly. Either one is not good news to any user.
The first step I suggest...is to remove all valued data files from that partition.
Then...I would run a hard drive manufacturer's diagnostic utility on the hard drive.
My experience is that a damaged/corrupted partition...results in wipe/clean install.
