Windows 7 & Windows 8 fail to start

Windows 7 fail to boot, what should I do?

Is Windows 7 failing to boot after you installed the loader or after you just installed a fresh new copy? Just do the following:

-->

*Insert your Windows disk and restart your pc

* Boot up the PC from your Windows installation disk by pressing F7, F8, F11, F12 or in some cases ESC

* Select the "Repair your computer" option

* Select "Command Prompt"

* Input "bootsect.exe /nt60 SYS /force" (without quotes)

* Restart the PC

If the above doesn't fix your boot issue then use the command "bootsect.exe /nt60 ALL /force" instead. Just make sure you remove all USB flash drives before you use the command.

Windows 8 fail to boot, what should I do?

Is Windows 8 failing to boot after you installed the loader or after you just installed a fresh new copy?

Just do the following using CMD:

-->

bootsect /nt60 sys /force /mbr

bootrec /rebuildbcd

bootrec /fixboot

bootrec /fixmbr

When you used "Automatic repair" option from "Advanced boot" menu, it show an error like: Windows can't fix your boot problems. For more information see file C:\Windows\System32\LogFiles\Srt\SrtTrail.txt

In this file I found a description of the system repair actions and at the end of file:

Boot status indicates that the OS booted successfully. Now, when I use the Advanced boot menu from Windows 8 (PC settings -> General -> Advanced startup) I receive an error:

Restart your PC to try again. It looks like something didn't load correctly. Restarting might fix the problem. If this happens more than once, you might also be able to find help by searching online for the specific error code. Erorr code: 0x8007090.

0x80070490 is the error code ERROR_NOT_FOUND.

What are the missing boot files and how can I restore them?
