Here's what happened, i always dualboot my laptop, windows and linux, i was fixing the grub menu, using easybcd as i always do. but i clicked install bcd by mistake on the first partition where windows 7 is installed and messed with the bios i believe. I can still boot to ubuntu but not to windows, here's what i see when i try booting to windows:

Windows failed to start. A recent hardware or software problem might be the cause. To fix the problem:

1- insert your Windows installation disc and restart your computer.

2- choose your language settings and then click next.

3- click repair your computer.

If you don't have the disc contact your system administrator or computer manufacturer for assistance.

File : \boot\bcd Status: 0x0000098

Info: the windows boot configuration data file does not contain a valid os entry

I don't have the disc, And there's no one i can contact for assistance. I don't want to reinstall windows nor to remove ubuntu. I was thinking about downloading wine on ubuntu, running easybcd on it and fix the issue using easybcd, if i can reach easybcd i know how to fix it, but i don't think my solution will work.

How about reseting the Bios setting? will i face any problem afterwards?

BIOS settings affect boot order, not the MBR code which you messed with. Here's Win7 if you want it: Where do I download Windows 7 (legally from Microsoft)? – Karan Feb 3 '13 at 22:22
@Karan i don't want to download microsoft windows 7, i just want to fix mine (fix, not reinstall it) and i have another laptop which has windows 7, can i use it to fix mine? maybe doing something like this? – Lynob Feb 3 '13 at 22:43
bcdedit, bcdboot etc. should all be available when you boot from the Win7 DVD, as will be the automated Startup Recovery feature. I wouldn't recommend using a System Repair disc on a different PC than one it was created on. – Karan Feb 3 '13 at 22:55
@Karan is there a small tool that can fix my problem? for example super grub disk can fix any grub problem, i really don't like to download a win 7 (3gb) just to fix this problem... is there another tool that i can use which does the job? i have a slow connection, the file may get damaged... – Lynob Feb 3 '13 at 23:01
I don't know of any small or even Linux-based utility to repair the BCD. – Karan Feb 3 '13 at 23:13

I solved the issue by following this tutorial. I used my brother's laptop to create a windows 7 system repair disk. I used the disk to repair the boot loader. As far as i know, the solution will work if both PCs are 64 bit. The repair disk have many options like "install drivers", I don't know if that option will work, if you use different PCs.
