Grub Help Please!

[skandranon]

I have been having so many problem with ubuntu!

I finally got it and windows 7 installed on seprate hard drives.

Windows installed first, then ubuntu 10.04.01.

Had to use the alternate ubuntu install cd to make it work. During the install it said there were no other operating systems installed on the computer and asked if grub could overwrite the master boor record. I knew this was something I wanted to do and if it was wrong it could most likely be fixed later.

So that being said, ubuntu has taken over the boot of my pc. No grub menu pops up. Not sure how to add windows to grub to make it give me a choice.

Can you guys help with this please?

Couple more things... I did try pressing shift durning startup to get grub to load, and nothing happened.

Here is my fdisk.

Windows is on sda and ubuntu is on sdb.. i think at least.

Also please note I am almost a complete n00b at ubuntu and linux in general. Please give details instructions on anything you would like me to do.

Have you tried to run

sudo update-grub

To see if a new grub.cfg file is created?

No I had not. Just did though.

Output was:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.35-22-generic
Found initrd image: /boot/initrd.img-2.6.35-22-generic

ls: cannot access /var/lib/os-prober/mount/boot

No idea what that means.

I have to go pick up my gal, be back in a hour.

It seems like you have the same problem as in this post: ubuntuforums.org/showthread.php?t=1374445 . Especially take a look on Post #5 ubuntuforums.org/showpost.php?p=9922017&postcount=5 , that might fix your problem.

(I hate this stupid 15 posts or more limitation for URLs)

I read that thread and that does seem to be on the right track.

However I am not sure how to:

Run a boot info scrpit

or how to

- navigate to /mnt in nautilus and delete /boot folder.

[tyho]

OK, do this at first:

sudo mkdir /mnt/windows
sudo mount /dev/sda1 /mnt/windows

(I assume /dev/sda1 is the partition Windows boots of)

I've never used Windows 7, so I don't know how it boots, but according to the mentioned forum post, there should be a folder called Boot on /dev/sda1. If there is also a folder called boot, that's your problem. You might want to rename it instead of deleting it, just to make sure you won't break anything.

You can rename it by running

sudo mv /mnt/windows/boot /mnt/windows/boot_backup

The new name of the boot folder will be boot_backup. You can name it whatever you want, boot_backup is just an example.

After that, run

sudo update-grub

again.

Now it should work. If not, post the output of update-grub.

tyho you rock! That worked perfectly. I now get a grub menu and windows is a option.

For some reason grub has two ubuntu installs listed is this normal? (Two ubuntus and two ubuntus recovery modes that is)

[jayd512]

Do they happen to have different kernel versions listed with them?
That will happen when doing system updates.
If you want to remove the unwanted entries, look to the Grub 2 Guide.
