NTLDR is Missing Windows 10

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that you’re facing issues when booting the PC, and I certainly appreciate your efforts in trying to resolve the issue.

We will certainly look into this for you.

Let’s try rebuilding BCD file and see if that helps.

Rebuild BCD:

You can try rebuilding the BCD file manually and see if the PC boots fine.

1. Create a bootable media and boot the PC using the media.
2. On the initial setup screen, select the language and other preferences and click on Next. (If you don't see the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.)
3. Now, click on Repair your computer.
4. On the System Recovery Options screen, select Troubleshoot> Advanced options > Command Prompt.
5. Now type in the commands and hit Enter:
   BOOTREC /FIXMBR
   BOOTREC /FIXBOOT
   BOOTREC /scanos
   BOOTREC /rebuildbcd
6. Restart the PC.

Rebuild BCD Store:

I would suggest you to export and delete the BCD store and rebuild the BCD store. Refer the steps mentioned below:

1. Create a bootable media and boot the PC using the media.
2. On the initial setup screen, select the language and other preferences and click on Next. (If you don't see the setup screen, your PC might not be set up to boot from a drive. Check your PC manufacturer's website for info on how to change your PC's boot order, and then try again.)
3. Now, click on Repair your computer.
4. On the System Recovery Options screen, select Troubleshoot> Advanced options > Command Prompt.
5. Now type in the commands and hit Enter:
   bcdedit /export C:\BCD_Backup
   c:
   cd boot
   attrib bcd -s -h –r
   ren c:\boot\bcd bcd.old
   bootrec /RebuildBcd

Let us know if you need any further assistance, we will be glad to assist you.

Using an older version of Windows 10 install media, I was able to get past the access "denied error" of the Fixboot command but came across another error and the machine will still not boot.

At the command BOOTREC /rebuildbcd

I get response: "Total identified Windows Installations: 1 Add installation to boot list?"

When I respond "Y", I get response, "The requested system device cannot be found."

Was finally able to repair with the above commands but had to find an older version of Windows 10 install media to handle the /Fixboot command. I had to use a new version of Windows 10 install media to issue the /rebuildbcd command which had to be issued twice.

Following this, running the repair startup tool in the Windows 10 install media twice repaired the problem.

Thanks for the help.

Glad you got it fixed but the NTLDR is relative to an XP boot loader.  The site below would have given you a command to change that.

How it got there in the first place is a little strange..
