Description of problem: Anaconda will create invalid GRUB config for "Other" OS and because of it is not possible to boot into this Other OS. In my case it is Windows XP and it is placed on /dev/hda1. FC4 itself is on /dev/sda. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Install FC4 on system where /dev/hda1 has Windows XP installed and /dev/sda is for FC4; 2. On system BIOS make the /dev/sda as primary boot device; 3. Install the FC4 to /dev/sda and during GRUB configuration change the device order (under advance settings) and set the /dev/sda first and /dev/hda as second sevice; Actual results: /boot/grub/grub.conf: title Other rootnoverify (hd1,0) chainloader +1 Expected results: /boot/grub/grub.conf: title Other map (hd0,0) (hd1,0) map (hd1,0) (hd0,0) rootnoverify (hd1,0) chainloader +1 Additional info:
Unfortunately, the need to do mapping isn't something which can be determined in an automatic fashion. For the setup of the vast majority of users, the configuration we set up is the better one to use.
