Question File system type problem

I have quite a serious problem I that cannot solve, therefore I would need some help from you. Namely I used to have W2K and Redhat7.2 running on the same box with GRUB boot loader installed on MBR. When I was trying to upgrade RH72 to beta RH73 via FTP the connection was once interrupted and that costed me a fortune: I couldn't boot any OS, either W2K or RH. So the most obvious thing for me was to try to restore the MBR so that at least W2K can be used. I first try with FDISK /MBR but it didn't work. Then I tried the FIXMBR function of W2K's Recovery Console, but that's also insufficient. In both cases W2K started to boot but I could never login. Anytime I entered my password it said "loading your personal settings" but immediately sent me back to the Ctrl+Alt+Del featured login screen. I have no clue why it is working that way. It's suspecious to me that the partion where W2K resides is displayed 'Non-DOS type" by FDISK and its system is OS/2 BMH. So somehow the partition type is of boot manager instead of NTFS.
So my question is: is there any way to revert the type of this partition back to NTFS so that W2K will work again (hopefully)? Any advice, please?
Thanks a lot!
PS: one thing I have learn that I should have made a revocery disk for W2K before I proceeded. Too late...:-(

OK. Here's how you do it. No 3rd party boot managers required.

1. Install W2K first. Leave enough room for Linux. (2 Gb +) This can be on the same disk, or a separate disk.

2. Install Linux, using "expert" mode. This gives you greater control over your installation.

3. When you install your Linux boot loader, choose LILO, not grub. DO NOT select MBR. Choose first sector of your root ( / ) partition. This will be /dev/hda2 if on the same disk, or /dev/hdb1 if on your second disk, etc.

4. Make the boot floppy, during the Linux installation.

5. When the Linux install is complete, reboot using the floppy created during installation.

6. With Linux up, insert a fresh DOS formatted floppy and mount it with "mount -t msdos /dev/fd0 /mnt/floppy".

7. Enter "dd if=/dev/hdb1 of=/mnt/floppy/bootsect.lin bs=512 count=1". This may vary, depending where your / partition is. Unmount the floppy & reboot.

8. W2K will come normally. Copy a:\bootsect.lin to c:\bootsect.lin

9. Edit c:\boot.ini to include: C:\bootsect.lin="Linux"

10. Done ! You should now have the option of booting W2K or Linux, using the W2K bootloader.

I have tested this with W2K Pro and Mandrake 7.2 and it works great.

Good luck.
