Bootmgr.exe compress to Bootmgr => Can't find hex value 4200430044. Use Bootmgr Recomplite (Joakim - reboot) or use BMplus (Conty9 - usbtor).

you can build a bootmenu in uefi bios instead of modifing bootmgr.efi.
edit uefi bios using "bootice",you could link the bootmanager to any path of bootmgr.efi,then put the bcd file to where the bootmgr.efi file is(put them in the same directory).

Search hex value 4500460049 and change it. For BCD, search hex value 4200430044 and change it (ex. B32, B64...). For BOOTMGR: same...

MANY THANKS 2012MsHs :)

Is it right for UEFI Loader of Windows 10 Anniversary ?.

P/S: Hex can not found any hex value "4200430044" in the file BootMgr.
