booting new hard drive disc - using XP

I've recently installed new 120G hard drive as a
secondary (PCI Card) master. All files were transferred
from secondary slave successfully. New 120G drive will
not boot up without XP installation disc. When booting
DOS can not find boot record and/or NTLS driver. I need
to transfer all files from slave on to master hard drive.

Do I have to erase 120G master drive, install XP,
manually transfer all files and other programs to master,
or is there an easier way?

Anyone else have this problem and what was your solution?
