Two ways first edit you menu.lst
As root or su vi /boot/grub/menu.lst and remove the lines you did not need
anymore.
Ore
Second install with synaptic the grub editor and you get it as a option application>system tools and you remove the lines you do not need any more

im needing help. i got rid of microsoft from grub but i think i messed up grub. i cant log on to my machine. i get

Error 11: Unrecognized device string

Press any key to continue...

this happened after i tried to install grub 2 and had a problem installing it. so i tried to uninstall it. i moved everything from my microsoft partition to this partition and now its not booting up. i do have a live cd with me if that will be any use.

Try to reinstall your boot loader Grub , see the steps in this documentation how to reinstall Grub

after reinstalling and reboot of your computer you will have everything working again

i did try earlier from the live cd but it didn't work. ill take a look at the link, i might not have done it properly.

im doing what it says but when it says type

Code:

setup (hdo)

i get

Code:

Error 12: Invalid device requested

the partition that grub is installed on is hd0,1.

what do i do from here?

vlademir · 03-27-2009, 04:58 AM

because the partition that grub is installed on is hd0,1.

you have to use

Quote:

root (hd0,1)

instead of root (hd0,0)

and then the command bellow to install it on hd0, that is MBR of the first HD.

Quote:

setup (hdo)

then type

exit

AS I do not know how you try the above command I do not know if its works ,normally the next commands we do it from the rescue mode
chroot/mnt/sysimage
grub install /dev/sda
exit
Hope it works

bcbotha · 03-27-2009, 05:33 AM

do i type
chroot/mnt/sysimage
grub install /dev/sda after i have typed
setup (hd0)

ronlau9 · 03-27-2009, 06:33 AM

Just type
Chroot/mnt/sysimage
grub install /dev/sda
exit
Some linux distro ask for the exit command some not
If you have a rescue mode than GRUB is install on sda and than try to reboot

bcbotha · 03-27-2009, 07:39 AM

Chroot/mnt/sysimage
grub install /dev/sda
doesn't work, i get the Error 12 message again. Any ideas what else i can try?

Of course is you're Ubuntu on sda2 . because SDA1 is normally windows
To be honest I am out of options maybe the quickest solution is
reinstalling Ubuntu
And if Ubuntu will be you're only Os let her use the hole disk .
If you later on decided to dual boot or triple boot with a other linux Oss it is always possible to shrink the partitions
Or divide you HD now in several partitions

It depends on how you have install Ubuntu now .
With separate /home than you can keep you're personal data , if you do not
format /home
But the programs Yes you the reinstall them all
If you let Ubuntu use the entire HD she will format the entire HD and you
started with a brand new system
