1. csm/efi 구분

bcdedit /enum {current} | find "winload.efi" && (bcdedit  /set %guid% path \windows\system32\winload.efi)

bcdedit /enum {current} | find "winload.efi" || (bcdedit  /set %guid% path \windows\system32\winload.exe)

or

set bios=exe

bcdedit /enum bootmgr | findstr bootmgfw.efi

if not errorlevel 1 set bios=efi

bcdedit /set !guid! path \windows\system32\winload.!bios!

2. guid 

for /f "tokens=1-5 usebackq delims=-" %%a in (`bcdedit /create /d "Setup Windows 10" /application osloader`) do (            set first=%%a

            set last=%%e

            set guid=!first:~-9!-%%b-%%c-%%d-!last:~0,13!

        )

or

for /f "tokens=1 delims={}" %%g in ('%BCDEDIT% /store %BCDSTORE% /create /application osloader') do set GUID={%%g}
