Grub problem after uninstalling Ubuntu 10.04!

2 posts · originally from https://geek.digit.in/community/threads/grub-problem-after-uninstalling-ubuntu-10-04.130070/

I have 4 partitions in my hard disk. I divided the 4th partition into 2 (ext4 and swap) and installed Ubuntu 10.04. After that when I logged into windows(XP) and deleted the 2 partitions on which I had installed Ubuntu, my grub disappeared. When I booted afterwards, the following error came:

unknown file system.
grub rescue > _

Now I cannot login to Windows. Please help!

Why did u formatted the partitions.. ??
Now u did dat already, so boot with ur XP CD and enter recovery console and type :
bootcfg /rebuild
fdisk /mbr
/fixmbr
/fixboot
and restart ur comp, see if it works !!
