Error:13 Dual boot Fedora 12-Ubuntu 9.10

[jdgreen]

Hey there! So I installed Ubuntu 9.10 on my laptop. Thereafter, I installed Fedora 12 on another partition. Now when I boot, my bootloader lets me select Fedora 12 or Ubuntu, kind of. When I select Ubuntu I get ERROR 13. Now... when I installed Fedora 12, I selected Ubuntu (or I thought) as another OS. Guess I messed up.

I need to know how I would fix this problem. I know it has something to do with GRUB, either its' conf file or the menu list, but I really don't know how to make the changes.

Any additional info you need, don't hesitate to ask. This is for school, so any quick responses would be doubly appreciated!

Thank you!

Hi and Welcome !

Boot up Fedora and mount / partition of Ubuntu. Post filenames of /boot folder of Ubuntu here.

mkdir ubuntu
su -c mkdir /dev/sdxy ubuntu
ls ubuntu/boot

Post the output of fdisk -l command too.

su -c /sbin/fdisk -l

Sorry that I haven't replied. I've been very busy with school and work along with other miscellaneous endeavors.

So in terminal I type

mkdir ubuntu
su -c mkdir /dev/sdxy ubuntu
ls ubuntu/boot

and then

su -c /sbin/fdisk -1

I'll try it today between classes. Thanks and look for a post around 4pm!

Replace xy with actual device name assigned to partition like /dev/sda1 or b1.

Its small L in fdisk -l

Okay I followed your directions and this is what happened.

[jdgreen@localhost ~]$ mkdir ubuntu
mkdir: cannot create directory `ubuntu': File exists
[jdgreen@localhost ~]$ su -c mkdir /dev/sda4 ubuntu
su: user /dev/sda4 does not exist
[jdgreen@localhost ~]$ ls ubuntu /boot
/boot:
config-2.6.31.5-127.fc12.i686 lost+found
efi memtest86+-4.00
elf-memtest86+-4.00 System.map-2.6.31.5-127.fc12.i686
grub vmlinuz-2.6.31.5-127.fc12.i686
initramfs-2.6.31.5-127.fc12.i686.img

ubuntu:
[jdgreen@localhost ~]$ su -c /sbin/fdisk -l
Password:

Usage: fdisk [-l] [-b SSZ] [-u] device
E.g.: fdisk /dev/hda (for the first IDE disk)
or: fdisk /dev/sdc (for the third SCSI disk)
or: fdisk /dev/eda (for the first PS/2 ESDI drive)
or: fdisk /dev/rd/c0d0 or: fdisk /dev/ida/c0d0 (for RAID devices)
...
[jdgreen@localhost ~]$

If i try

fdisk -l /dev/sda4

it says it cannot open the file. I didn't know how to mount the / partition of ubuntu. Unless that was included in the terminal commands in your directions?

Try just:

/sbin/fdisk -l

[jdgreen]

Got it! Thanks!

[root@localhost jdgreen]# /sbin/fdisk -l

A question: /dev/sda3 * 9978 10003 204800 83 Linux

What does the * mean? Current partition in use?

[devils casper]

You have mounted wrong partition. You are using Fedora's GRUB now and we need contents of Ubuntu's /boot folder so that we can edit Fedora's GRUB.

Execute this in Fedora

mkdir ubuntu
su -c mount -t ext3  /dev/sda2 ubuntu
ls ubuntu/boot

Post output here.

[jdgreen]

This is my result

[jdgreen@localhost ~]$ su -c mount -t ext3 /dev/sda2 ubuntu
su: invalid option -- 't'

[jayd512]

From your current directory, execute

ls -l

Post the output.
Maybe you already have the proper directory in place.

*EDIT*
Those are both a lower case 'L'
