Win 98 and Win 2000 Server dual boot

Greetings of peace,
I installed Win 98 SE. Later, i wanted to install Win 2000 Server to a different partition (same hard disk) but unable to do so.
Primary partition c drive : 4 GB followed by D drive :4GB and E drive : 5GB respectively.

I used win 2k server CD ask the initial seting up to format the D or E drive. But, after the formatting, the message says “it is unable to format and ask me to check the hard disk”.

Again, i went to win 98 and checked all the 3 partitions but found no problem.

Is there a size limitation per partition for Win 2000? Why i cannot install the Win 2k Server on d drive or e drive. I even tried to install in c: but failed also. What is the best way to resolve the problem.

Thank all of you in advance.
Regards
Pandav
