<P><FONT face="Courier New, Courier, mono">This is my second upgrade to FC4 from Red Hat 9. The first one was uneventful. When I tried another machine tonight, grub was hanging on reboot. </FONT></P>
<P><FONT face="Courier New">I tried a grub-install /dev/hda from rescue mode, but that didn't work.</FONT></P>
<P><FONT face="Courier New, Courier, mono">I finally did a grub-install --recheck /dev/hda which took quite a while to complete. When I rebooted, I finally saw the grub boot screen. </FONT></P>
<P><FONT face="Courier New, Courier, mono">When I choose the kernel to boot, I received an 'error 17' which the grub manual indicates that grub cannot recognize a filesystem format.</FONT></P>
<P><FONT face="Courier New, Courier, mono">This is weird since this box has only been linux and the partitions are either swap or ext3. The fdisk information seems to be in order. Note that since I choose upgrade during the FC4 installation, it did not (or was not supposed to) change my partition table and / or format the filesystems. I don't think the installer changed the fdisk info - it looks the same as before.</FONT></P>

<P><FONT face="Courier New">I don't know grub, but reading the manual I am confused as to why the grub-install set the root to (hd0,1). Since my boot partition is /dev/hda1, shouldn't this be (hd0,0)?</FONT></P>
<P><FONT face="Courier New">It's also interesting that the rescue option can load my filesystems just fine.</FONT></P>
<P><FONT face="Courier New">From rescue mode, I did a chroot /mnt/sysimage and then changed the /boot/grub/grub.conf root (hd0,1) to root (hd0,0) and ran grub-install /dev/hda</FONT></P>
<P><FONT face="Courier New">I check top from another TTY and there is no CPU time for the grub-install command (top reports it in Sleeping status) and my drive does not indicate any accesses. I think it basically hangs.</FONT></P>
<P><FONT face="Courier New">So, I'm stumped and looking for suggestions.</FONT></P>
