My macbook has three os at the same time: macOS, bootcamp win10, ubuntu. When booting, I choose os through rEFInd. After I removed ubuntu, I found that only windows and efi boot were left when booting. After entering the efi boot, the screen is grub. In order to restore macOS, I referred to the following methods: macOS partition startup Volume type FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF

After macOS was repaired, I found that win10 could not be accessed. the error is "NO BOOTABLE DEVICE - INSERT BOOT DISK AND PRESS ANY KEY" I guess it may be modified when adjusting disk type. gpt add -i 3 -b 244551680 -s 245682176 -t EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 disk0

Can anyone help? thanks a lot.

You can try the following command while booted to macOS Recovery.

fdisk -e /dev/disk0

The command is interactive. You should input the following.

n

244551679
edit 2

244551680
245682176
flag 2
quit

Update

If you see the following display when booting Windows, then you should rebuild the BCD file.

enter image description here

The steps to rebuild the BCD file are given below.

  1. Use the Boot Camp Assistant to create a Windows 10 install disk. This should be a flash drive. Do not remove the existing Windows 10 installation.

    enter image description here

  2. Boot from the flash drive and proceed until you reach the following display. (You need to reach this point in order for the Windows drivers to automatically load.)

    enter image description here

  3. Press shift+F10 to open a Command Prompt window.

  4. Enter the following commands. When bootrec prompts for input, enter a.

    attrib -h -s c:\boot\bcd
    del c:\boot\bcd
    bootrec /rebuildbcd
    attrib +h +s c:\boot\bcd
    exit
    
  5. Restart the Mac and boot Windows from the internal drive.

  • I finished entering these commands. Now there is a blue screen. title is Recovery and error code is "0xc000000e". Is this the right step? Any suggestions for next steps? thanks a lot.
