I have tried getting this from computer forums, but am impatient, and they are the slow. I am dual booting (two hard drives) Linux and Xp pro now using GRUB installed on the MBR. I have the Xp HD set to master and the Linux jumped to slave. Now when I install WinXp 64 it is going to erase the MBR and consequently GRUB. Now, I am planning on trying to reinstall GRUB on the MBR using Code: chroot /mnt/sysimage grub-install /dev/sda off the rescue disc, but if for some reason it doesn't work I am going to try using the Windows bootloader. Now, I know it should work just fine, since before my brother in law wrote it to the boot.ini when I was dual booting Xp in english, and Xp in german on another HD. But the problem is, he added the line, I didn't, so I don't know what to write. What I am looking for is if some can write out teh bootloader to give the choice to boot from the Linux HD also I know it should look something like this... Code: multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Home Edition" /fastdetect multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="FedoraCore 4" /fastdetect But not to clear on the specifics. Thanks ahead of time.
