Okay so I wanted to try Ubuntu 9.10 on my computer partially because it is so damn old to run windows 7 and partially because I wanted to give it a try. 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

sh:grub>set root=(loop0)

sh:grub>linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda1 loop=/ubuntu/disks/root.disk ro

sh:grub>initrd /boot/initrd.img-2.6.31-14-generic

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.

Open Terminal (Applications->Accessories->Terminal)

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.
