The drive appears as "unknown" and I get the following error: to quit, reboot and go to the command screen "recovery console" which requires and advices to setup with guidance and help of a Dell certified technician.
I tried to contact Dell support to guide me with command prompts and repair the disk, and they provided me the some information which seems obsolete now.
Seems my hard disk is now destined for Linux only - and I thought Microsoft's products were the mother of all viruses!
So I had W2K installed on my "test" pc but wanted to try something with Ubuntu.
Unfortunately it exits immediately with "none fatal errors" and suggests that this is because of bad sectors.
However I ran the manufacturer's (fujitsu) test utility and it claims all bad sectors are fixed (marked out). ok I just re-installed ubuntu on the disk and it works fine so obviously this is not a disk problem per se.
In most cases, the cause is a driver compatibility issue.
To troubleshoot a failed upgrade that has returned a result code of 0x C1900101, analyze the extend code to determine the Windows Setup phase, and see the Resolution procedures section later in this topic.
