Install went fine...now grub error 22!

[legionX]

Ok, I'm using the 10.4.3 Wesley's Patch DVD, I burned it and rebooted, the install came up and it installed just fine, except when it got to the end where it said it was going to restart the computer it just sat there with the litting spinning circle and never rebooted. Finally I manually rebooted the machine and now when I go to start up I get

 

Grub Error 22

 

So apparently OSX is installed and all, but something is wrong with the bootloader. I only have one harddrive in the machine right now, and it's only got one partition, the HFS one that OSX is installed to. What can I do to fix the boot problem and get OSX booting?? Thanks.

Sounds like your master boot record (MBR) has some Grub bootloader code left in it, and Grub can't start because you blew away the partition with the grub application.

 

You need to fix your MBR and make your OSX partition active, that *should* fix your problem.

 

From the install CD, hit F8 at bootloader screen. Enter in '-s' (minus quotes, of course) to boot into single user mode.

 

You shouldn't need to mount your HFS partition when the command line comes up, so don't worry about running fsck or mount.

 

Enter in these two commands:

 

1. fdisk -u /dev/rdisk0

This will write a new MBR to your hard disk that should work fine with OSX.

2. fdisk -e /dev/rdisk0

This will bring you into fdisk. Make your partition active by typing these in these commands:

a) print (this will show you all your partitions, although it sounds like you only have one)

flag 1 (this marks your first partition active)

c) write (writes the new partition table to the disk)

d) exit

3. reboot your box (type 'reboot' or 'shutdown -r now', or power cycle, doesn't really matter).

 

Cross your fingers and hopefully enjoy a booting OSX.

 

Let me know if this works.
