Issues dual booting Windows 10/Windows 7 on UEFI system RRS feed

  • Question

  • Hi all,

    This is my situation:

     I'm running into troubles that I think are having to do with UEFI. Secure boot is disabled.

    I've tried two different ways:

    Situation 1:

    1. I created a bootable USB using Rufus (GPT partition style, FAT32)

    2. Result: When booting I get this error.

    Situation 2:

    In disk management:

    1. I created a new expandable VHD.
    2. I initialized the VHD. It asked for the partition style (GPT/MBR). I chose GPT.
    3. I created a new NTFS volume on the VHD and assigned drive letter X: to it.
    4. I mounted the Windows 7 ISO on drive E:

    In the Command Prompt
    5. I installed Windows on the VHD using the following command:
    Dism /apply-image /imagefile:E:\sources\install.wim /index:4 /ApplyDir:X:
    6. I added boot files to the partition using the following command:
    bcdboot X:\Windows (source)

    Result: when booting Windows 7, I only see a black screen. Not even the ''Starting Windows'' screen shows up.

    I would be grateful for any assistance.
