Windows 10: If I manually tell BCD the free space to use, will that fix it?

Update Error0x80070643 doesn't know I changed the partions, so BCD thinks it's where WIN put it. If I manually tell BCD the free space to use, will that fix it?

:)

 

Error code 0xc000000f, BCD corrupted

Hi Andre,

As per the description, I suggest that you follow the steps below to fix BCD

1. Right click on the Start Menu and select Command Prompt (Admin)

2. Here type/paste the commands listed below

Bootrec /fixMBR

Bootrec /fixBoot

Bootrec /RebuildBcd

3. Once done restart the PC and check.

Hope this helps

 

How to clean up BCD entries? Rebuild the BCD?

This is normal that under Recovery Environment, The letters are re-assigned. This is why you have to be careful and select the correct one.

Advice: Never use Easy BCD with Windows installed using GPT disk. Use Easy UEFI instead provided you know what you are doing. Easy BCD only works with MBR disk type.
Base on the screen shot above. Your disk 0 is your new Windows and your disk 1 contains the old Windows. Disk 3 contains a 512MB Fat32 partition and I don't know what that is. I suggest you disconnect disk 3 for now before proceeding.

Let rebuild new BCD's for both disk 0, and disk 1. Please follow step by step on the 2 screen shots below. On step 3, write down the drive letter for PM981_New. In the screen shot, My Windows is still assigned to C but it might be different from yours. In step 10, if the drive letter is different than C, then use the letter in step 3.

Do exactly the same for disk 1, this time select disk 1 in step 4 and assign letter V in step 7, Use V and the drive letter for Old Windows in step 10. This will create a new BCD for PM981_Old and you will be able to boot separately from boot menu.

From boot menu, select which one to boot from.
Once booted into Windows. If you wish, you can set up dual boot for Windows old & New. Under This PC, look for the drive letter of the offline Windows and type:
bcdboot X:\Windows where X is the letter of the offline Windows

Thought so. That's the error Windows Setup encountered also.

(The EFI boot partition file system has become corrupted. The partition has to be formatted, and the boot files need to be rebuilt. If you're familiar with WinRE, you should be able to fix this using the instructions in the article How to Rebuild the EFI Boot Partition, BCD and Boot Files)

Or, for step-by-step instructions, do the following.

Run:

• label C: OS
  

Press Enter.

And then, access the Windows Recovery Environment. To do so, from the login screen, click Shutdown, then hold down the Shift key while selecting Restart.

Open WinRE Command Prompt.

Type:

• mountvol y: /s
  
• diskpart
  
• list vol
