[Help] Can't boot to windows (8.1) after resizing partition

You are in Internet Recovery. Your Local Recovery seems to be corrupted.

If I boot with ALT key and I chose the other disk (I think it's recuperation), will it do the same thing as local recovery?

You can try it, but Command+R will try that partition first. If it find any issues, it will fall back to Internet Recovery. If you are being asked for your Wireless connection information, your Mac is using Internet Recovery.

Hi Loner T,

I got the same issue and followed all of your instruction but I can't boot Window. It always report that I need to repair system with error code 0xc000000e.

1. I disabled SIP as your advice

2. I followed your instruction and the log as follows:

3. I attached screenshot of Windows bluescreen.

Can you help to check what's wrong with my steps? Thank a lot for your support.

The error code indicates BCD corruption. You will need to use Command Prompt, make the partition read-write using Diskpart.exe, and run bootrec.exe /rebuildBCD to make this work properly.

Thank you for your suggestion. I tried the following steps:

1. Clear attribute read only of the volume Bootcamp which contain Win10 by using Diskpart.

2. Rebuild boot configuration data by bootrec.exe

At the step 2, after entering "bootrec.exe /RebuildBcd", the system scanned and found 1 Windows installation at C:\Windows. It ask "add installation to boot list" and I choose "yes". Later, it reported that "the requested system device cannot be found".

Can you tell me what wrong here? I'm using recovery disk of Windows 10 and manipulating commands from command promt.

You need to look at Diskpart and map the System volume to a drive letter which has your BCD, otherwise BCD rebuild will fail.

I'm not sure I'm following you. Currently I have 4 volumes in Diskpart: volume 0 is the new partition I created from Macintos HD (E:), volume 1 is BOOTCAMP one (C:), volume 2 is one in Usb stick (F:), volume 3 is recovery disk which I'm running command line (D:). How should I do mapping system volume with the volume which has BCD (C?)? Thank you.

Please see 0xc000000e Error on Windows after Partition Resize as an example.

I was able to mount EFI volume on Mac, however when I boot to Windows recovery mode by USB stick I could not see EFI volume to assign different drive letter as your suggestion to rebuild BCD. Can you help at this stage? Thank for your patience.

Can you post a screen shot of your diskpart list?

Please check the screenshot.

The Diskpart is reading the MBR we created which 'merged' the EFI and OS X into a single volume, which is Partition 1. You only see Partitions 1-4. The BCD is located in the EFI partition. You may need to recreate the MBR using 2 4 5, and re-check if you can see and rebuild the BCD.

This is a nasty state, because the Recovery HD can be corrupted by Windows. Once you rebuild the BCD, you need to switch the MBR back to 3 4 5, before you try to boot Windows.

I recreated MBR using 2 4 5 but was still unable to see EFI volume. The list of volume in Diskpart is the same, the difference is list of partition where size of the first partition is 200MB, which might refer to EFI. Should I backup data and reinstall Windows now? It took me more than a day to look around solution for this trouble and I'm not sure if there is solution for my nasty state.

The first 200MB partition is your EFI partition which holds your BCD.

You can re-install Windows, but you will need to wipe the extra partition and merge it all back, so your partition list before you start Windows installation must have EFI, OSX and Recovery HD only. After you re-install Windows, if you recreate a new partition, you will run into the same issue again.

What year/model is your Mac?
