Invalid Paramter when formating EFI Partition with Diskpart in WinPE RRS feed

  • Question

  • Hello all,

    I am using a batch file for installing Windows 10 via a WinPE USB Environment.

    Using WinPE from Build 1607 and everything runs fine. But with WinPE from Build 1709 we become an Error messung during the Diskpart process.

    > Select Disk 0
    > Clean
    > Convert GPT
    > Create Partition EFI Size=300 Offset=1024
    > Assign Letter=S
    > Format FS=FAT32 LABEL="System" QUICK
    > EXIT

    But the Format command brings an Error Message because of "Invalid Parameter"?
    Waht is the different between Build 1607 and Build 1709, because the error is only with WinPE from Build 1709.
