This question already has an answer here:

I had a dual boot system for Windows 7 and Linux 10.10 . I am new to linux and hadnt upgraded it before ir reached its end-of-life. So I decided to delete the partition in which linux was installed and in the same session downloaded the latest linux version 12.04 using WUBI in windows. When I rebooted my computer, I get this error: "Unknown Filesystem" Grub Rescue >

I have seen other threads that involve making a livecd. As it turns out I have already installed the latest linux, so is there a way to get my PC to boot to either 12.04 Linux or Windows 7 without making a live CD

Latest Ubuntu is 13.04. You could make livecd (on USB for example) and install new Ubuntu on older one (don't forget to format old Ubuntu partition). Then when booting - GRUB should see both Ubuntu and Windows. Always worked for me.

I understand that you are not able to boot neither Linux nor Windows?

I had formatted the partition where linux 10.10 was installed before using WUBI. – Rhijul May 4 '13 at 17:57
@Rhijul Boot from livecd and try this. – shardival May 4 '13 at 18:02
