Only problem I didn’t have a Boot CD and my old computer won’t boot from a USB. So I tried WUBI and installed Ubuntu within windows. I was all set to try Ubuntu now. Ubuntu was running quite good , I had even shifted my development environment from Windows XP to Ubuntu 9.10. After running for a few days Ubuntu’s update manager notified me there are some updates, so i clicked Update and the update started. After the update it asked to Restart Computer and so i did.

After the restart when i tried to boot into Ubuntu , the GRUB screen came and i was like what do i do now ? I am a techie but i am not that into Linux so i was clueless there.

So i had to boot into Windows again , fire up Firefox and hunt the web for a solution as now i had everything in my Linux Environment.

Finally i found a solution  and compiled everything at one place.

Please follow the following steps if you too got stuck at the GRUB screen in a WUBI installation after doing a Linux Kernel Update / Update to Ubuntu

  1. sh:grub>set root=(loop0)
  2. sh:grub>linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro
  3. sh:grub>initrd /boot/initrd.img-2.6.31-14-generic
  4. sh:grub>boot

please note /ubuntu/disks/root.disk is the location of your WUBI installation (default being C:\ubuntu)

this will enable you to boot into Ubuntu Back

After booting  into Ubuntu follow these steps to not to see that GRUB screen again during starting up.

  1. Open Terminal (Applications->Accessories->Terminal)
  2. Type sudo update-grub2 and click Enter, enter your administrator password and voila your GRUB list is made again. and you’ll not the GRUB screen again

I hope that helps. if you have any doubt please say in comments.
