    Recently i bought a desktop pc:

    LENOVO C20-00 All-in-One (ideacentre)
    come with Windows 10 Home SL v10.0.10240.

    i want to install Windows 7 Professional x64 as a secondary OS.

    Before i do installation, i was prepare
    1. an UFD support UEFI with Rufus (or manually using diskpart) + add USB 3.0 driver
    2. Temporary disable "Secure Boot" -> will be automatically disabled when CMS = [Disabled]
    3. Turn on CMS to [Enabled] -> [Disabled]
    4. Turn Turbo Mode to Disabled -> Not need

    But when i start to boot from UFD UEFI (via F12), i got an error mesage like this:
    Status: 0xc000000d
    I also try alternative media like the original bootable DVD but i got the Windows starting screen hang up.

    Please any advice how to solve this problem. Thanks in advanced.

    Thank you, case closed - my problem SOLVED :clap:

    BCD 0xc000000d means the bcd is corrupt...

    Are you able to reboot normally after removing the dvd or flash disk ?

    Try this:

    - Format the USB thumbdrive FAT32 (simply by using explorer)
    - Extract the ISO to it
    - On the USB thumbdrive go to: "\EFI" and create a folder called "boot"
    - Open the install.wim with 7z and go to: "sources\install.wim\1\Windows\Boot\EFI" and copy this file: "bootmgfw.efi" to the just created "boot" folder and rename it: "bootx64.efi"

    Now you have created an UEFI and Legacy BIOS bootable USB thumbdrive.

    I don't see you mentioning you have shrunk or free up space on a seperate partition to install 7 SP1 on, don't try to install a second windows to the same partition as the other windows.

    Just boot with the w10 media and let it repair the bootloader.

    That's one of the few things that the automatic repair is able to fix reliably. But just in case, just use the command line

    [FONT=&amp]bootrec /RebuildBcd
    bootrec /fixMbr
    bootrec /fixboot  
    Stop hovering to collapse... Click to collapse... Hover to expand... Click to expand...

    Just a quick FYI, after you get things installed remember that every time you boot to Windows 7 it will delete any volume shadow copy data used by the Windows 10 partition. This will effect things like Previous Versions of files and System Restore.

    This happens because Windows 7 doesn't know how to handle volume shadows from any OS higher than itself. It essentially sees them as corrupted and the default action is to delete them.

    No problem with my main system (Windows 10), it can boot normally.

    I was done these steps you've mentioned above (Rufus and manual).
    Yes, i had prepare separate patition for W7 already.

    Should i do these instructions? My system run normally.
