dual boot 32 64 bit problem
 

:newbie:

Hi. I have tried twice now to install both 64 and 32 bit FC6 on an x86_64 machine. Each time, I first installed the 64 bit version on one partition (using the MBR as the selection where to store the boot information), and then installed the 32 bit version in an adjoining partition (again, using the MBR as the selection where to store the boot information). Once the second OS was installed, the menu was adjusted so that it listed both versions (i.e., 64 and 32 bit versions). However, the 64 bit version would no longer boot once the 32-bit version was installed. When the kernel started loading, the following error message was generated several times: request_module: runaway loop modprobe binfmt_464c. Any ideas as to what may be causing this and how it can be fixed? :scratch: RobA>

Make sure you either use the actual drive/partition (root=/dev/hda1 for example) instead of the partition labels (root=LABEL=/) or make sure the partition labels are different in the kernel line(s) in the /boot/grub/grub.conf file(s) and in the /etc/fstab files.

Examples;

kernel /vmlinuz-2.6.18.1 ro root=LABEL=/ quiet

becomes;

kernel /vmlinuz-2.6.18.1 ro root=/dev/hda1 quiet

and

becomes;

Or;

kernel /vmlinuz-2.6.18.1 ro root=LABEL=/ quiet

becomes;

kernel /vmlinuz-2.6.18.1 ro root=LABEL=/64 quiet

and

becomes;
