Installed FC5> Wrote over Ubuntu MBR: How do i add Ubuntu Partition to Grub Loader

Free_beer · 09-28-2006, 11:25 PM

Hi,

This is the process I followed (below) and the out come is Ubuntu file system is still on my hard drive yet I can't boot up Ubuntu because FC 5 wrote over Ubuntu's Boot Loader file. What is the code to add Ubuntu to the Fedora Core 5 grub.conf so I can boot up Ubuntu?

Process: on 80 gig HD
1. Installed Win 2k3 (20 gig) sda6
2. Installed Win XP SP2 (5 gig)sda5
3. Installed Ubuntu 6.0 Desktop (21 gig)sda1
4. Installed FC 5 (7 gig)?

Fedora Core 5 grub.conf file

Code:

default=0
timeout=15
splashimage=(hd0,2)/boot/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.15-1.2054_FC5smp)
	root (hd0,2)
	kernel /boot/vmlinuz-2.6.15-1.2054_FC5smp ro root=LABEL=/ rhgb quiet
	initrd /boot/initrd-2.6.15-1.2054_FC5smp.img
title Other
	rootnoverify (hd0,0)
	chainloader +1

The "Other" points to the Windows boot loader. The Windows boot loader can boot Win 2k3 server just fine yet it CAN NOT boot up Win XP!! (I get an error)

Need some more information, what's in FC5's /boot/grub/device.map and what's the output of "fdisk -l"

Without knowing that it's just a guess from here out but you can try:

Code:

title Ubuntu 2.6.15-26-386
	root (hd0,2)
	kernel /boot/vmlinuz-2.6.15-26-386 root=LABEL=/ ro quiet
	initrd /boot/initrd.img-2.6.15-26-386
	boot

That's if you have a separate /boot partition, you'll also want to remove "hiddenmenu" so you can choose which to boot without having to press escape.

Sure. Let me know if this useful:

Device.map

Code:

# this device map was generated by anaconda
(hd0)     /dev/sda

Ouput of fdisk -l

Code:

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

ok, this entry should work for you

Code:

title Ubuntu 2.6.15-26-386
	root (hd0,5)
	kernel /boot/vmlinuz-2.6.15-26-386 root=/dev/sda6 ro quiet
	initrd /boot/initrd.img-2.6.15-26-386
	boot

Good shit homie. It work for the most part. I only had to add one thing to the kernel code. Which was

Code:

 kernel /boot/vmlinuz-2.6.15-26-386 root=/dev/sda6 ro quiet vga=0x318

Thanks
