I´ve been using dual boot with Windows XP and SUSE. I installed myself suse on another computer so I really don't need the dualboot anymore so frequently. My new idea is to reinstall XP and install vmware to run suse.
As we all know Windows needs to be reinstalled after sometimes, because all the registry entries and unused programs make the os slow as hell.

I have 1 harddisk, splitted into 3 partitions. First one as NTFS, second one to suse and third one is fat for both to use.
I want to format the whole harddisk and make one (1) NTFS-partition.

I have never done this so I really need your help.
The magic question:

Can XP overwrite the grub settings and install the windows default bootloader to the harddisk?

Is this procedure safe to do with just xp installer-CD, or do I need to uninstall something first or what?

By default, Windows XP will always annihilate your current bootloader This will leave only XP in the boot menu, or any other versions of Windows if the exist. When you re-install a Linux version after this, it would then put both in the boot menu.

1. Use the Windows xp cd and start the recovery console.
2. Then type fixmbr
3. Grub is removed then, but not the Linux installation.

This is one of my reasons why Im asking this thing, because I have already tried fixmbr and it did nothing . It said the operation was succesfull, but when i restarted my computer I was stil presented to the same grub list as before the fixmbr.

What do you mean with "grub list"?

I mean that the command fixmbr does nothing.
Before the fix I had grub and after the fix I have grub.

"grub list" == The normal grub, where it lists my available OS-opinions.
Here is a pic, although its from the Suse installer, you hopefully can understand what I mean. http://www.madpenguin.org/images/rev...se10/boot1.jpg

I have used fixmbr many times without any problems. It is possible, that your bios protects the master boot record.
Refer to your Mainboard manual.

Just boot from your XP cd, and when you go thru the install, it detects ALL partitions and you just use 'D' to remove them all and 'C' to create a partition of the whole drive. It formats NTFS, then you install Windows, and bam, goodbye Linux and all your drive data.
