fidsk /mbr should reinstall the windows bootloader. You do know that you can just use grub to boot windows.

that won't "unistall" linux. it will just reload a "default" MBR....so it will be back to just windows. linux will still exist, you just won't be able to boot to it without a bootdisk....until you reinstall a bootloader that supports linux

the diffetence between dos fdisk /mbr and linux fdisk /mbr is that dos has that command and linux doesn't

if anyone know's of a way to delete the mbr in linux I would appreciate if they would post it (without any 3rd party tools)

Probably this will do it.
dd if=/dev/zero of=/dev/hda bs=512 count=1

Read: input file is /dev/zero, output file first IDE disk, block size 512b,
dump only 1 block

I think i got it.if i am having teo linexes+windows and i want to uninstall one linux,after deleting the respective partitions,i need to modify the lilo/grub.conf file,deleting those entries abt the deleted linux.And there is no need to modify MBR.Am I right??
