Windows won't start up

[EndoReX]

I got this problem after i got windows updates and after this i shut computer. now my computer doesn't boot.

When i open my computer i get ''Start windows normally'' or ''start windows repair''. When i try to boot normally, my computer freezes on windows logo and nothing happens. When i try to repair, i get only black screen. I can't boot even on safe mode.

I can't boot on installation cd and i tried to change things in bios but it didn't help

I have replaced cmos battery, and done all, but none of that helped.

Please help!
Sorry about my bad english.

Try "Last Known Good Configuration" as described here:

(The URL refers to Vista, but applies equally to Windows 7)

It just freezes at windows logo. Same as ''Start windows normally''

To boot from the Windows installation disc, press and hold F11 as soon as you turn on the computer. A boot device menu should appear. Highlight "CD-ROM drive" (or the model name of the drive) and press <Enter>.

If F11 doesn't work, restart and try F12 instead.

If still no success, test the hard drive with the drive manufacturer's diagnostic software for DOS which loads from a bootable CD. The links are here: http://www.tacktech.com/display.cfm?ttid=287
