I have got another problem with my T21 Thinkpad. When booting up I get message: Hard Drive Not Installed, I can then get past this and the receive next message: Operating System Not Found. I have inserted Windows 2000 disc(genuine) but cannot progress and further than this screen, could someone PLEASE help.

The first message says it all! Either your hard drive has died, or become disconnected 
or its controller has died. So bios can't detect it - so obviously no system.

Are you able to get into the bios settings to check stuff out? (and to set boot order 
to CD first, so your 2k install disk will boot).

Probably worth finding the hard drive under one of removable covers on back, disconnected 
and reconnecting it - but suspect you may need a new drive/install if you want to 
rescue this machine.

I am unsure of how to get to hard drive. On the back are two removeable covers. The first lets me into memory slots, the second I do not know what it is but there is a metal tab and something covered in yellow(?) clear covering.

Didn't see your post from the 10th. You said you managed to do a clean install! Which 
obviously meant the hard drive was present. If it really was a clean install (ie, 
you either formatted the drive or removed and created partition during the install 
process), then if errors during or shortly after that, suggests a hardware problem 
of some sort. But you didn't sound convinced it was a clean install!

If the hard drive is not accessible through cover on the back, it may be via a slot 
in the side or under the keyboard on the front. Can you find any information online 
about your thinkpad model? (google it). Hard drive should be rectangular, c. 2.5x3.5 
inches, probably silver, and probably with information about it printed on.

After a little bit of tinkering & surfing I did manage to get hard drive out.

Am looking to get another as reinstalled windows but it has crashed again with the 
same start up message and have seen them on Ebay pretty cheap.  This week needed 
this to be working as sons pc was getting fixed and so he was stuck! aahhh!!
