Boot issues after recent updates

Hi

I have an ACER aspire netbook which had a base OS of Windows XP on which i installed Ubuntu using WUBI and everything was fine until i applied some updates which caused Ubuntu to stop booting and come with this error:

NTFS5:no wubildr and pc is restarted.

After doing some research, i tried copying wubildr and wubildr.mbr from my c:\ubuntu\... to c:\ which did not fix the problem.

I then got the latest iso for Ubuntu 10.10 and booted it off my usb drive and used update-grub which then caused Windows to stop booting and came with grub rescue console.

I then used Windows on my usb drive to fix mbr but got a blue screen instead. I then used ms-sys on \dev\sdb2 which is my c drive from Ubuntu Live to fix mbr and now i am getting error: unknown filesystem followed by grub rescue console. Now when i boot Ubuntu from usb, mouse has stopped working but that is not a big deal.

I have lost 2 days and need help urgently for my Masters. I ran the boot-info script and the following is the result:

Few other things that might help you narrow down the problem: I can't see menu.lst or grub.conf anywhere on my boot partition.

I need both windows and ubuntu up and running.
