error: no such partition. Grub rescue

Question

I deleted my Linux (Ubuntu) partition from Windows and I forgot to repair the MBR. I don't have my windows boot CD with me nor a CD drive. Is there any small utility that can be easily downloaded (I know about hiren CD but it's about 500 MB and I don't need that whole stuff) and which can be used from an USB drive? If yes, please explain the steps to perform. Thank you

UPDATED:
Small Linux live CDs are OK since I can boot them from an USB drive using pendrivelinux

Solution

I would recommend using this software to make a USB boot disk of either knoppix and follow the instructions here to repair.

So, is your windows partition working fine?

I want to completely start my windows PC by installing these boot drivers or whatever needed

sir i have already said that i need a small software which will do as much as i need, not more than that. Knoppix is approximately 3.7 GB and I am not going to download that.

Then google lightweight linux distros. You can probably find many under 500 MB. It will be much easier for you to find a linux distro that does what you want (and will be around when you want something else) than to find a piece of software that does exactly what you want.
