Grub 1.5 error booting

[mackan547]

Hi guys

So I have Windows 7 installed.
Then I installed Ubuntu.
Then Backtrack 4.

So that corrupted the ubuntu boot!

title Ubuntu 8.10, kernel 2.6.27-7-generic
uuid bf3b0243-7670-4601-b8fa-61fb6f7c32c5
kernel /boot/vmlinuz-2.6.31-20-generic-pae root=UUID=882ea2ed-31f9-45ed-93cc-21b75f190091 ro   quiet splash
initrd /boot/initrd.img-2.6.31-20-generic-pae
quiet

So this is what I tried with and I get a error18.

Now what would be the correct exact code?

This is how my current boot config looks

quiet

Anyone have any ideas?

Hi there,

Try changing the menu.lst file with a livecd.
And change/add:
root=UUID=882ea2ed-31f9-45ed-93cc-21b75f190091 real_root=/dev/sdx
Replace the /dev/sdx with your root device.

If you need help show me your disk setup with disk -l please.

Hey thanks for the reply.

I get an error: Error 11: Unrecognized device string.

I tried sda3 and sd3 (where 3 is the part. I have ubuntu installed on)

I can boot fine in to Windows and Backtrack 4 ^^ just not ubuntu.

Disk -l doesn't work in Backtrack 4.

Ah sorry mate that was a typo... ( fdisk -l )
Try using:

title Ubuntu 8.10, kernel 2.6.27-7-generic
kernel /boot/vmlinuz-2.6.31-20-generic-pae root=/ real_root=/dev/sda3 ro   quiet splash
initrd /boot/initrd.img-2.6.31-20-generic-pae
quiet

initrd /boot/initrd.img-2.6.31-20-generic-pae
quiet

The code you gave my just directly gave my an error 15!

This is what I get from fdisk -l

According to menu.lst file file posted by you, real_root=/dev/sda2 but its NTFS.
Where is Ubuntu/BackTrack partitions? You have only one Linux Partition.
It looks like you have overwritten Ubuntu by Backtrack. Does Backtrack boot up fine?

[Feeyo]

Yep you installed Backtrack over Ubuntu partition. So that one is lost
I also do not see a type 82 on your disks (SWAP) partition.

For the next time installing a linux system I do hint to also create a swap partition.

Sorry guys, but you're wrong. My backtrack and windows boots fine. Ubuntu is installed on a NTFS disk and worked fine from the start, so windows is one one part. backtrack on one, and ubuntu on one so no I didn't overwrite anything (since I reinstalled ubuntu once again on the NTFS drive) I did install it on a ntfs drive from the beginning and it worked fine then

So It's just the boot settings that are ****ed up.

Or does ubuntu have to be on a linux part. because I installed it from windows and if it wound't had been a ntfs part. I cound't accsses it right? so then I wound't be able to install it :P


So pretty sure it's just a grub setting... (booting also fails from windows bcd.)

[Feeyo]

So you installed Ubuntu with the Wubi tool? Does this mean it has installed Ubuntu as a Virtual Machine on your ntfs partition?

Sorry this is new for me and my help stops right here

Good luck though hehe.
