NT installation proble

I have windows NT on my system, Once I tryed to install Linux on to the same system, I was installed, But win NT is not booting. I removed all the partitions and create new partitions and format in fat16 and NTFS but It I could not boot. My system is not booting. It is not going to the Hard disk. After ” VERYFYING THE DMI POOL DATA ” my system is halting, I tryed so many times to install again NT. The first part of the Installation is successfull complated. But It is not booting again after removing the CD of NT software. If I put the CD and I again boot my system it is taking the first part of the installaion which is already complate, How can I overcome the problem.
