I did this in recovery ""bootrec /fixmbr" writes disk's boot sector (commonly called MBR)
"bootrec /fixboot" writes partition's boot sector (commonly called VBR).
The Windows boot process on a GPT disk is significantly different from an MBR disk.
- Unlike an MBR disk, a GPT disk does not have an active partition.
- Unlike an MBR disk, a GPT disk does not have a boot sectors (no MBR, no VBR).
- On a GPT disk, the bootloader is just a regular file inside the EFI system partition.
Windows boot process on GPT disk.
1. "Windows Boot Manager" entry in the list of bootable UEFI devices in the BIOS settings.
2. \EFI\Microsoft\Boot\bootmgfw.efi file in the EFI system partition.
3. \EFI\Microsoft\Boot\BCD file (Boot Configuration Data) in the EFI system partition.
4. \Windows\system32\winload.efi file.
Both Windows installations must use the same EFI system partition.
diskpart
list volume (check your EFI system partition number)
select volume # (replace # with your EFI system partition number)
format quick fs=fat32 (optional: format your EFI system partition)
assign letter=z
list volume (check the volume letters of both your Windows partitions)
exit
bcdboot x:\windows /s z: /f uefi
- replace "x" with the volume letter of your first Windows partition
bcdboot x:\windows /s z: /f uefi
- replace "x" with the volume letter of your second Windows partition
- /s z: is your EFI system partition you assigned above
- firmware type /f uefi is not needed if you have booted USB flash drive in UEFI mode
format fs=fat32 quick
diskpart
select partition X
set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b (EFI system partition GUID)
gpt attributes=0x8000000000000001 (sets EFI + hidden attributes)
exit"
bcdboot D:\Windows /l en-us /s Z: /f UEFI
But i still have the same issue
