If y'all can kick into Windows, we highly recommend using our Recovering the Windows Bootloader with EasyBCD guide instead.

If you're on an EFI/UEFI auto or have GPT disks, you will demand to applyEasy Recovery Essentials (i-click Windows recovery CD) instead.

Booting from the Windows Installation DVD

If y'all can't get these instructions to work for you, don't have the Windows setup CD/DVD, are worried something might go wrong, or are but looking for a safety & reliable way of fixing your kicking bug with just a unmarried click, download a copy of Easy Recovery Essentials (our recovery discs) and use information technology to get your PC dorsum up and running in 5 minutes. It supports Windows 10, Windows eight, Windows 7, Windows Vista, Windows XP and Windows Server editions.

Put your Windows setup DVD or your System Repair Disc in the drive and restart your PC.

Bold you've properly configured your BIOS to kicking from CDs/DVDs before hard drives (or you can printing F12 if your PC supports it to boot from the CD), you should get a prompt request you to "Press any key to boot from the CD/DVD…"

Press a fundamental, and the CD will begin to load.

If you are using your Windows Installation CD, y'all'll meet a dialog asking you want to Install Now, or in the lower left corner, an selection to "Repair your Computer," which you'll want to click.

If you're using our recovery CD, Like shooting fish in a barrel Recovery Essentials, just go to the next department. If yous're having problems booting from the recovery CD, run into our guides on creating a bootable CD and setting up your PC to boot from the CD-ROM drive.

Subsequently selecting your language, the recovery CD will scan for operating systems on your drive. Select the operating arrangement to repair from the list displayed on the screen, and then press Next to continue.

Depending on which version of the CD yous're using, y'all'll see a welcome screen similar the ones below:

Stride Zippo: Scan the disk

From the carte, choose the "Launch command prompt" option.

We will utilise the command line feature to a run a filesystem scan, designed to observe and fix problems affecting data integrity and reads/writes from/to the disk, that tin be caused past viruses, hardware failures, unsafe shutdown, power surges, and more.

Once the command prompt has launched, execute the following control:

chkdsk C: /f leave

Note that yous may need to replaced C: with a different letter if it complains that the partitioning was not found.

Attempt One: Automated Repair

Clicking on the "Attempt automated repair…" text with the green pointer at the top of the screen will cause the recovery CD toattempt to repair your bootloader and boot card.

Assuming your boot files accept not been too badly corrupted, this step should conclude with a "Issues resolved" message and prompt you to reboot. Information technology could literally be this like shooting fish in a barrel to fix your PC.

If the automatic repair characteristic is not successful, or later rebooting you lot discover that your PC still does non work, read on.

The Automatic Repair only fixes one thing at a fourth dimension, and you might need several things fixed (MBR, bootmgr, boot folder). So boot from the recovery CDonce more and echo the whole procedure.

Attempt Ii: Manually Repairing the Windows Bootloader

Desperate times call for desperate measures.

This time, we're going to select the "Launch command prompt" option and endeavour to manually tell the Recovery Console what needs to be fixed. Chances are, this is as far every bit you'll accept to go; hopefully it'll get the job done.

Go ahead and select "Command Prompt" from that listing, and you lot should get a window not dis-like to the one you see when run cmd.exe from Windows.

Let'south start by telling the recovery console to fix our MBR and bootsectors:

bootrec.exe /fixmbr bootsect.exe /nt60 all /strength

Then inquire it (nicely!) to try and rebuild your BCD data from scratch:

bootrec.exe /rebuildbcd

If you're lucky, this'll piece of work and you'll come across a message telling you everything went OK.

Reboot your PC and try booting back into Windows to see if it worked. Don't forget to remove your Windows Vista DVD or Recovery DVD from the drive, or yous'll end back in the repair center!

Attempt Iii: Nuclear Holocaust

Back at the main page of the recovery center, go ahead and select "Command Prompt" yet again from that list.

The first lodge of business concern is to make sure the MBR and bootsector contain the right references to the Windows bootloader:

bootrec.exe /fixmbr bootsect.exe /nt60 all /forcefulness

Now we get rid of the old BCD registry, and create a new one instead.

Note: We're assuming that the kicking drive is drive C: below. If your computer is configured differently, be sure to employ the appropriate bulldoze letter here instead.

attrib -h -s C:\kicking\BCD del C:\boot\BCD bcdedit /createstore c:\boot\bcd.temp bcdedit.exe /store c:\boot\bcd.temp /create {bootmgr} /d "Windows Boot Manager" bcdedit.exe /import c:\kicking\bcd.temp bcdedit.exe /set up {bootmgr} device partitioning=C: bcdedit.exe /timeout 10 attrib -h -southward C:\boot\bcd.temp del c:\boot\bcd.temp

Bootloader Cleanup Results

The first two commands may fail. Assuming you entered them correctly, that is fine; it simply indicates the BCD does not nevertheless exist.

Now nosotros have a clean, working Windows bootloader. Just we need to add a Windows entry to it:

bcdedit.exe /create /d "Microsoft Windows" /application osloader

bcdedit.exe should return a message with a GUID for the newly-created entry, something like this:
The entry {c0dfc4fa-cb21-11dc-81bf-005056c00008} was successfully created.

Yous'll need to utilize the value that bcdedit.exe returnedfor you beneath, along with the drive letter of the alphabet for the drive that Windows is installed to:

Again, make certain to replace C: with whatever the correct drive is for your Windows Vista/7/8 installation.

bcdedit.exe /set {c0dfc4fa-cb21-11dc-81bf-005056c00008} device partition=C: bcdedit.exe /ready {c0dfc4fa-cb21-11dc-81bf-005056c00008} osdevice partition=C: bcdedit.exe /set up {c0dfc4fa-cb21-11dc-81bf-005056c00008} path \Windows\system32\winload.exe bcdedit.exe /set {c0dfc4fa-cb21-11dc-81bf-005056c00008} systemroot \Windows

And, last of all, tell the bootmgr bootloader to list the new entry or else it'll remain hidden:

bcdedit.exe /displayorder {c0dfc4fa-cb21-11dc-81bf-005056c00008}

Calculation a Windows entry to a bootloader

Now your bootloader has been completely removed and rebuilt from scratch. If you got this to work, feel free to consider yourself one of the finest graduates of the NeoSmart Technologies Institute of BCD Learning.

At this betoken, you accept aclean, untouched, and (hopefully) fully-working bootloader with one entry for Windows.

Become ahead and reboot your PC, get back into Windows, and utilise EasyBCD to further tweak the bootloader to your eye's content.

We advise backing up the BCD registry immediately with EasyBCD before making any changes.
