Where did you put Grub for the new FC5 on the second haddrive? You should have put it in the MBR of hda (presuming that's the first harddrive). This would have resulted in getting the Grub menu for Grub on the new FC5 install at bootup, which should also have a chainloader set up for Windows, but not for the old FC5 on hda, as the old Grub would have been overwritten by the new one. You probably know this, but just in case. To put Grub from the new FC5 into the MBR of hda (the one with Windows on it), bootup the rescue disc, select the / partition of the new FC5 which gets you into a /mnt/sysimage environment. Then type, chroot /mnt/sysimage, then grub-install hda. Exit twice (I think), then reboot the machine, removing the rescue disc. If you still want to boot the old FC5 on hda, theres a bit more work to be done. Presuming that you now are able to boot into the new FC5, and know the / partition, or /boot partition, if you have a separate one for the old FC5 on hda, open a terminal, su to root, open a text editor (your choice), and go to /boot/grub/grub.conf . We'll add a chainloader to link to Grub for the old FC5. Presuming you only have a / partition for the old FC5, the chainloader will look like this. title Old FC5 root (hda,x) (changing "x" for the / partition) chainloader +1 Save, and exit the text editor, and terminal. Shut down the machine. Using the rescue disk once more, this time go to the / partition of the old FC5 on hda, chroot /mnt/sysimage, then, grub-install hdax , changing "x" to the / partition of the old FC5. Exit the chrooted environment, remove the disc, and reboot. Now when you reboot, you'll get the new FC5s Grub, and can try out the chainloader to link to the Grub you've just installed on the / partition of the old FC5. You should now have the old FC5s, Grub menu, and can boot the old one. While you were in grub.conf, it is usefull to change a few things. Change timeout to 30. Put a # in front of Hiddenmenu, and remove the "rhgb quiet" from the end of the kernel entries, which will allow you to see all the text on bootup. All the best. Nigel.
