Is there a way to fix NT 4.0 boot sector?

I was trying to install new disk drives in a Raid controller using MegaRaid utility, which is a program that comes up at the startup. It is a PCI SCSI Disk Array controller. There were three arrays already configured on the server. I was adding a new configuration.
When I was almost done configuring the new drives, it asked me to reboot the server. I did that and then it hung up on the Windows BIOS screen (which is a gray screen with all the information like how many drives, how much ram etc..).
So basically it was not recognizing any of the disk drives. Some one came who has seen this before and told me that the boot sector might have been corrupted. So he asked me to get the boot disk, he copied four files (boot.ini, bootsect.dos, ntdetect.com and ntldr) into floppy and we booted off the floppy drive instead of c: drive and it worked. but while we were doing this we had to undo our installation of new disk drives.

So my question is, there is a way to fix the boot sector at all..some kind of disk repair utility..may be..?

In windows 9x fdisk has an undocumented parameter that restores the boot sector:

fdsik -mbr

This might help.
