Bootcamp Windows Error 0xc0000225 after Partition Resize

Dear all,

I had windows 10 in bootcamp for many years. Recently I decided to resize partitions and add sum space to windows. I reduced the size of mac partition from disk utility and restarted the system and suddenly the choice to entering windows disappeared. I reverted back the mac partition but nothing changed. I installed gdisk and did what I found in other threads. After that the choice to enter windows appeared but when I clicked it it showed error 0xc0000225. I booted with windows installer and did startup repair but nothing changed. I did fixboot and fixmbr and rebuildbcd but still nothing changed. Who can help me?

Thank you

Take a look at El Capitan has deleted my bootcamp window… - Apple Community. It uses Testdisk to locate the NTFS partition. If you can locate it, it may be possible to recovery your Windows partition.

Modifying partitions, once Windows is installed, is not supported. The error code you see indicates a Windows BCD error. It may be possible to recover Windows. What is the year/model of your Mac (do not post the serial number) and teh current macOS version? Do you see Windows files in macOS Finder?

Thank you for response

I have executed testdisk and saw windows folders.

After that I executed sudo disk /dev/disk0 and did the things in threads but still windows cannot boot.

I did fixmbr, fixboot, and rebuildbcd but does not work.

What is the next step?

Here are details:

diskutil list

/dev/disk0

Check the harddisk size: HD jumper settings, BIOS detection...

Your GPT entry shows...

488124416  488980480      3  GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7

which is different. Can you correct the entry? If you are unable to use the exact values, we may need to change the default alignment of GPT Fdisk from 8 sectors to 1 sector.

Thank you

I did the process one more time. Now I see files in finder.

The Error changed to 0xc000000f

I booted with installer and did fixboot, fixmbr, and rebuildbcd but rebuildbcd said:

"The requested system device cannot be found."

Now I cannot even boot with windows installer.

What is the next step?

The BCD for a an EFI Boot is located in a different location than the legacy BIOS Boot. See the description of the "/s" qualifier in https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/bcdboot-command-line-options-techref-di.

Your 2014 Mac supports both EFI and legacy BIOS installations. If your Windows installation is an EFI installation the BCD must be be rebuild after you set the correct System Device.

If /fixBoot /fixMBR and /rebuildBCD were run on the X: device which is your USB external boot device, it will not correct the BCD on the internal disk. Also, see https://apple.stackexchange.com/questions/308729/recover-bootcamp-efi-folder-fix-boot-entries.
