At the beginning I have been Windows 7 on /dev/sda1. After that I have installed Ubuntu in /dev/sda7 and set Grub partition to /dev/sda1. Which broked down Windows 7 boot. Ubuntu have booted normally from Grub Menu, but when I choosed Windows 7, grub disappared and after 1 second appeared, and doesn't load. After that I have searched for some fixes for Windows 7 boot, and I do some "fixings". The result – Grub doesn't load.
At this moment I have broken Windows 7 loader and broken Grub. And sitting with Ubuntu Live CD. How can I fix this with Ubuntu live CD? If possible please give step by step explanation, because I newbie in Ubuntu and Linux.
EDIT: Grub loader fixed. But anyway… Windows 7 doesn't load from Grub.
I'm using Grub2.
EDIT2 As I understand I need to run bootrec.exe /fixboot to fix Windows 7 bootloader. But I don't have Win7 DVD at this moment. Any way to do same from Ubuntu?
EDIT3 Boot Info Script RESULTS.txt is here: http://pastebin.com/Z70fKQHJ

There is no way to fix the windows 7 bootstrap from Ubuntu, you will need to do so with the windows 7 DVD but, which size is sda1, if it is +/- 100Mb, you should not have much troubles fixing it but, will need to reinstall grub to another partition. If it is way bigger than 100Mb, this mean it was not the system reserved space and that you have installed Grub over your windows 7 thus, deleting windows 7 completly....
