grub will not work

[melenor]

All right i recently made my ubuntu partition bigger, but the grub no longer works following previous guides i did this

>sudo grub
grub> find /boot/grub/stage1
find /boot/grub/stage1
 (hd0,1)
grub> root (hd0)
root (hd0)
grub> setup (hd0,1)
setup (hd0,1)

Error 17: Cannot mount selected partition

I have no idea how to fix this.
Thanks for any help.

You're using the root and setup commands with the arguments flipped. Try:

root (hd0,1)
setup (hd0)

[meierfra.]

Post the output of

sudo fdisk -lu

What program did you use to resize Ubuntu?

What happens when you try to boot Ubuntu? Does the grub menu appear? (You might have to press "Esc" after the bios screen) Any error messages ?

Error 17: Cannot mount selected partition

Do you get this error at boot up? Or at the "grub prompt" in the LiveCD?

[meierfra.]

root (hd0,1)
setup (hd0)

+1. (I didn't noticed that you used "root (hd0)")

-I used gparted
-grub menu appears but says that the partition does not exsit

partition that ubuntu is on it /dev/sda3
I have followed what you said meierfra and will reboot right now.

[melenor]

just rebooted it says

 
Boot from (hd1,1) ext3 
Error 15: File not found 
Press any key to continue.

[meierfra.]

Post the output of

sudo fdisk -lu

and

sudo mount /dev/sda3 /mnt
cat /mnt/boot/grub/menu.lst

[meierfra.]

Try this:

At the grub menu at boot up, press "c". Type

find /boot/grub/stage1

The output will be of the form (hdX,Y)

Press "Esc" to get back the grub menu. Select Ubuntu and press "e". At the new screen press "e" again. Change the line to

root (hdX,Y)

(Use the numbers you got from "find /boot/grub/stage1")

Press "enter" and then "b" to boot. If this lets you boot into Ubuntu, you still have the make the changes permanent. Open "menu.lst" via

gksudo gedit /boot/grub/menu.lst

Change

"# groot=(hd?,?)" to "# groot=(hdX,Y)"

Save the file. Back in the terminal

sudo update-grub

That should be it.

If this does not work, post the information I requested in my previous post. And also the output of the "find /boot/grub/stage1" command

sudo mount /dev/sda3 /mnt

mount: you must specify the filesystem type

cat /mnt/boot/grub/menu.lst

cat: /mnt/boot/grub/menu.lst: No such file or directory

I will do that one right now and post results

EDIT: What line do i add the

root (hdX,Y)

-btw "find /boot/grub/stage1" returned "(hd1,1)

on the first line it has uuid and alot of numbers
then comes kernel that has the "root=UUID=" and numbers from first line

[melenor]

just replaceing the first line gives me an error however, I think that is because of the "root=UUID=78587026-b7b5-4943-a56d-d361f269fdb3"
the line i replaced was
"uuid 78587026-b7b5-4943-a56d-d361f269fdb3"
