    Hi all,

    I´m trying modify bcd with these commands

    Code:
    @echo off
bcdedit /store "%~dp0_output\boot\bcd" /copy {default} /d "Windows x64" >> "%~dp0_output\boot\GUID.TXT"
for /f "tokens=2 delims={}" %%i in ("%~dp0_output\boot\GUID.TXT") do (set GUID=%%i)
::del /q /s "%~dp0_output\boot\GUID.TXT"
echo %GUID%
bcdedit /store "%~dp0_output\boot\bcd" /set %GUID% device "ramdisk=[boot]\sourc64\boot.wim,{7619dcc8-fafe-11d9-b411-000476eba25f}"
bcdedit /store "%~dp0_output\boot\bcd" /set %GUID% locale "cs-CZ"
bcdedit /store "%~dp0_output\boot\bcd" /set %GUID% osdevice "ramdisk=[boot]\sourc64\boot.wim,{7619dcc8-fafe-11d9-b411-000476eba25f}"

pause
    Problem is when Im trying to read output from txt to variable, nothing is loaded into %GUID%.
    First command return txt file with GUID, but every run is generated new, so what I´m doing wrong with loading GUID from this output?
    Code:
    The entry was successfully copied to {7aa217ea-aa81-11e9-8389-001a7dda7113}.
    Can someone help how to solve my problem, please?

    Thanks

    Solved: to save GUID the right command is
    Code:
    for /f "delims={} tokens=2" %%I IN ('bcdedit /store "%~dp0_output\boot\bcd" /copy {default} /d "Windows x64"') DO SET GUID=%%I
