Windows 10: bootrec /rebuildbcd does not find Windows XP

Hello -
the original problem was that msconfig showed the system stuck in Selective mode with
"use original boot configuration" grayed out, so attempts to put the system back to Normal mode failed.

I used the established procedures to recreate the BCD (the following commands in WinRE command prompt):
attrib c:\boot\bcd -h- s -r
ren c:\boot\bcd bcd.old
bootrec /rebuildbct (enter Y to add the entry)

The thing is, it does not find the Windows XP I have installed, so it boots directly to Windows 10,
instead of offering me a menu where I can choose Windows 10 or "older versions of Windows"

To add insult to injury, the msconfig shows the system still stuck in Selective mode, so recreating
the BCD was a waste of time.

Does anybody know how to add the XP install to the BCD ? I know I can restore the old BCD I backed up,
but I was interested in seeing if there was a way to add it to the fresh BCD.

Thanks for any info.
Dave

I learned about bootrec at:

How to fix MBR-helper in Windows 10

However, I tried those four steps:

Bootrec /fixmbr

Bootrec /fixboot

Bootrec /scanos

Bootrec /rebuildbcd

and I still receive the error message in the title of this thread.

Neither scanos nor rebuildbcd found a windows installation, but I'm looking at my C drive from the recovery command prompt, and don't know why it isn't finding it. there is a C:\WINDOWS directory with 45 files and 79 dirs.

How it particular does bootrec determine it found a windows installation? Does bootrec work with [unlocked] BitLocker drives?

 

bootrec /rebuildbcd can't find windows

Hey,

The command bootrec /rebuildbcd identificiates 0 Windows installations.

I already checked this thread Total identified Windows installations: 0 identified Windows installations: 0 - Microsoft Community

I found this tutorial:

bcdedit /export c:\bcdbackup
attrib c:\boot\bcd -h -r -s
ren c:\boot\bcd bcd.old

The second command with attrib is not working because it can't find the path.

What shall I do?

 

Is your hard drive MBR or UFEI and is it a gpt disk?

 

No it's legacy, normal BIOS/MBR

Let's say the Windows XP partition gets the drive letter F: with Windows 10 running. The command to run would be:

bcdboot F:\Windows /addlast /d

 

Thanks for this, I have not tried it yet. Out of interest I also found an alternate method, step 2 in the "resolution"

I'm very cautious about EasyBCD; in some circumstances it installs it's own version of NTLDR and messes
with the boot.ini and I'm trying to avoid that.

 

Hello - I used these commands from the article mentioned above to manually add the Windows XP
partition with ntldr to the BCD:

Bcdedit /create {ntldr} /d "Earlier Versions Of Windows"
Bcdedit /set {ntldr} device partition=d:
Bcdedit /set {ntldr} path \ntldr
Bcdedit /displayorder {ntldr} /addlast

This did work, except it now booted with the graphical screen instead of the text based menu and options.
This is how it was:




This is it after rebuilding the BCD (this sample is from the net but it's the similar appearance)




What is that determines whether you get this graphical screen or the simple line selection
I mentioned above Some setting in the BCD?

For now I abandoned the BCD rebuild and restored the original, which I had backed up.
Once restored, the simple text based menu was back

 

In my experience with dual booting Win10/XP, if rapid shutdown/hybrid sleep is disabled, you get the old text menu.
If it is enabled, you get the Win10 graphical BCD.

 

Sometime in the past i had entered the command
Powercfg -h off
This was before I recreated the BCD. I think this disables fast start and hibernate. Assuming some indication of this makes it into the BCD, perhaps things got out of step when the new BCD was created
