Are you saying that you want to reinstall both OS's? Where you can have an option to choose between Linux and Windows at boot time?

Welcome to the forums!

To clear the MBR (master boot record) only, leaving partition tables alone, you can run this code from the terminal under Linux:

dd if=/dev/zero of=/dev/sda bs=446 count=1

You'll need to replace /dev/sda with your actual device name such as /dev/hda.

If needed, you can use the fdisk -l command to determine your device name:

fdisk -l

...note that it's a lower case letter L and not a number 1 in the command.

If you want to install both OS's fresh... easy to do! Re-install XP first. Then, when you install Fedora, just tell it to install GRUB in the MBR. I wouldn't actually tell you that part... but you asked about over-writing MBR anyway. Linux will take care of the dual-boot feature of it. Let us know in the Fedora or Installation sub-sections of the Forums if you have any other questions.

*EDIT*

Don't forget to back up important data first!

The easiest way to install a fresh copy of both operating systems is to install Windows, then install Linux. You can use the same partitions they already reside on if you wish. The Linux bootloader will overwrite the Windows bootloader when it's installed.

You might not need to worry about removing the current MBR at all because it will be overwritten by each OS. If you should decide that you do need it removed, you can follow the instructions already posted above.

Also, please stop posting duplicate threads as it's against the forum rules to do so.

Best of luck with your new installations.
