How to Manually Repair Windows 7 Boot Loader Problems

follow few steps

step 1: The first thing you’ll need to do is boot off the install disc, and then click through until you see the “Repair your computer” link in the lower left-hand corner.enter image description here

Step 2 :You’ll need to choose the correct installation of Windows and then click the Next button.enter image description here

Step 3 :And then you’ll get to the System Recovery Options screen, where you can get to the Command Prompt.

Repairing the Master Boot Record

If you want to restore the master boot record, you can simply type in the following command:

bootrec /fixmbr

You can also write a new boot sector onto the system partition with this command (which is often more useful):

bootrec /fixboot

And of course, if you just use bootrec /? you’ll be able to see all the options.enter image description here

Using the Automated Startup Repair

Of course, all this command-line stuff is probably not necessary in most cases. You can usually just use the Startup Repair option from the Recovery menu… enter image description here

It’ll check for problems and probably fix them. If not, then you can always use the command prompt.Have you ever needed to restore your boot loader to get Windows working again?

If you copy the whole article (including images and the finishing sentence) from another site, you should at least link the original source I think. –  Gene Jul 25 '13 at 6:37

If you manually install the boot loader its make changes only in MBR if you select the option "system restore" thus its make changes, its depend on the windows which used to repair –  Shailesh Jul 25 '13 at 8:22

In order to repair Windows Bootloader, you'll need an external recovery disk, as you need to boot on a windows system and your grub is broken (you deleted its files).

If you don't have one, you can still make one. You just need to download a Windows 7 ISO and burn it. And if you don't have a DVD to burn it, you can put it on a bootable USB, with this Microsoft tool.
Well, you still need an other computer for that.

In your situation, an automatic repair should bring your bootloader back. If it doesn't, you can still try opening a console in the repair/install DVD environment and run Bootrec.exe/FixBoot.

@ANTRIX repairing boot sector with a Windows installation DVD cracked or not, should not affect your Windows installation at all, only the bootloader. However, you do not neeed a cracked copy to do this, any Windows 7 installation DVD should be ok. –  Levans Jul 25 '13 at 7:55
