LinuxQuestions.org - Grub Dual Boot Mandrake 9.2 and Win2000 Invalid Boot Disk

--------------------------------------------------------------------------------

A few weeks ago, I installed windoze 2000 and mandrake 9.1 with the GRUB bootloader on a 20 gig primary master hd. Well, I aboslutely fell in love with Mandrake and have attempted to do a more permanent reinstall (one 20 gig drive holding both Win2K and Mandrake was not enough).

For this I changed my setup a little. I formatted and reinstalled Windoze on the 20 gig primary master. Everything went well, except when windows rebooted during the install, Grub was still in the MBR. I had to boot to a DOS floppy and clear the MBR using fdisk /mbr before continueing the Windows install. Then, I added another 20 gig primary slave and installed Linux on this the hdb. The install when fine. Again, I choose GRUB as my bootloader. It detected both installs. I rebooted hoping to see GRUB but instead all I got was "Invalid boot disk in a: Please insert Boot Disk". I used the Mandrake CD to reinstall the bootloader. I got the same results. So, I rewrote the MBR to a windows MBR using Mandrake CD. Same results. So, I tried using FDISK to repair the MBR. Same results.

I attempted to reinstall Linux, but this time the bootload install failed.

Does anyone know what I'm doing wrong? Having I killed my MBR?

Thanks,
