problem with multibooting

Ever since my new harddisk I encounter many problems creating an multiboot enviroment.
This is the problem:
First I installed win98, secondly win-nt server, third win2k server.
Before installing win2k u have to use sp5 on win-nt, otherwise it is not possible to install win2k.
So I did.
What happened is that win2k had removed the bootsector of win-nt.
Than I had to face a problem, which is the os is removed, but not the bootsector.
My question:
1st, How do I remove that bootsector of both the systems, win-nt and win2k, for re-installing these os.
2nd, why is installing several os on one disk giving now that much problems, I never had this before.
What did I do wrong or what did I overlooked?
With regards, Mario

Older versions of windows (95,98,etc) had an undocumented switch for fdisk that would wipe out the boot sector for you:

fdisk /mbr


I have no idea if this still exists in current versions of windows (2k, nt). If not, find a 95 or 98 boot disk, boot into dos mode and run the command above.

BTW, this is a Unix forum -- how is this a Unix related question?
