Boot Ubuntu Server Without GRUB

I'm in a hurry. I've searched all around but evidently I'm not looking up the right think or I'm too much of in a rush to recognize anything as my solution.

I've installed Ubuntu Server for something that I need to run in a little while. I only need it once and while installing I encountered a fatal error installing GRUB. The problem is that now I don't know how to get into my box. I have Windows 7 on the other drive but because there is no boot manager setup, it goes straight into Windows7.

I don't need any fancy solutions, I just need a fast way to boot into my Ubuntu Server and hopefully later set it back to auto boot into Windows7 again.

EDIT

I've also looked in msconfig and EasyBCD. Neither of them show my newly installed Ubuntu Server, only my Windows7.

Thanks!

Taken from : https://help.ubuntu.com/community/Boot-Repair Please refer to it for more options.

The easiest way to use Boot-Repair is to burn one of the following disks and boot on it. (http://sourceforge.net/projects/boot-repair-cd/files/)

Boot-Repair-Disk is a CD starting Boot-Repair automatically. (English only, 32&64bits compatible, based on Debian-live so Wifi drivers are not recent).

Boot-Repair is also included in Ubuntu-Secure-Remix (multi-languages, ok for Wifi, based on Ubuntu 12.04 LTS, run Boot-Repair from the Dash)

Remark : you can also install the ISO on a live-USB (eg via UnetBootin, LiliUSB or MultiSystem).

install lilo bootloader http://lilo.alioth.debian.org/

Take a look at Boot-Repair which should be able to solve your trouble and repair the broken boot records, so you should be able to boot both systems again.
