    :hi:

    Haven't been here for a long while as I’ve been using my desktop lately.
    Recently, I got hold of a P751DM2 and so the nightmares could begin:

    I'm desperately trying to create a bootable USB drive to install Win 7.
    (Please no debate about the OS. I'm aware of the flaws but I need it for a handful of programs. Probably Win 10 will be installed in the near future or multiboot, but right now, Win 7 it is) ;)


    What has been tried by me so far:

    - Tried the excellent tutorial by bfishman (http://forum.notebookreview.com/thr...om-a-usb-3-0-thumbdrive.783921/#post-10134666)

    - I have tried diskpart (fat32, primary+active partition), moved all files from the 676919 ISO (Prof + SP1 x64) to the USB drive, then I extracted the sources\install.wim\1\Windows\Boot\EFI\bootmgfw.efi, renamed it to bootx64.efi and moved it to efi\boot. I also copied the folder efi\microsoft\boot to efi\boot.

    - Windows built in Format Tool: FAT32, MBR and did the extracting and moving folder action as described above.

    - I have tried both Rufus 1.4.1 and Rufus 3.1.1 in GPT mode for UEFI.

    - I have tried the useless Balena Etcher Tool.


    All this results in the same result: The P751DM2 won’t boot all over (error codes below).

    I even tried to install Windows on my old P150HM. Afterwards, I inserted the SSD into the P751DM2. Then I used gparted live to migrate from MBR to GPT, but of course this only led to a corrupt GPT table.

    ---------------------------------------------------------------------------------------------------
    Error Codes:

    - Rufus:
    UEFI turned on, Secure Boot turned off:
    Windows failed to start. File: \EFI\Microsoft\Boot\BCD. An error occured while attempting to read the boot configuration data
    UEFI turned off:
    Rufus built in error code as formatted for UEFI Boot only

    - Diskpart:
    UEFI turned on, Secure Boot turned off:
    Windows failed to start. File: \EFI\Microsoft\Boot\BCD. An error occured while attempting to read the boot configuration data
    UEFI turned off:
    Reboot and select proper Boot device

    - Balena Etcher:
    UEFI turned on, Secure Boot turned off:
    Windows failed to start. File: \EFI\Microsoft\Boot\BCD. An error occured while attempting to read the boot configuration data
    UEFI turned off:
    Reboot and select proper Boot device

    So basically all the same error again and again.

    -Windows built in Format Tool:
    UEFI turned on, Secure Boot turned off:
    No response.
    UEFI turned off:
    First success (Windows is loading files) :)
    Then BSOD: The BIOS in this system is not fully ACPI compliant :mad:
    ---------------------------------------------------------------------------------------------------

    The P751DM2 BIOS doesn't provide any Legacy option which I could turn off.

    BIOS: 1.06.02, EC: 1.05.03.
    My vendor doesn't support any newer updates. Besides that, I don’t think that a BIOS flash would help in this case.
    By the way, what happened to the Prema Mod?


    I would like to use the NVMe pure 64bit Samsung NVMe Driver and the USB P750DM-G USB 3.0 Driver, both for Win 7.
    But first I would need a bootable setup...


    The USB drive Win 7 setup starts just fine on my UEFI business Acer notebook, the Clevo needs to make a fuss.
    I’m feeling so incredible dumb asking for help for a stupid 15 minutes job, but I’m working on it for 2 afternoons now and I'm just getting frustrated :mad: Could anyone please give me a hint?
    Which filesystem would you suggest and why? FAT32 or NTFS? MBR or GTP?

    Everything you want to do is possible and I have done it numerous times. I have had none of the issues you are experiencing with 6 different Clevo laptops. All have had a @Prema BIOS, so I don't know exactly what the limited configuration options are in the stock Clevo BIOS.

    Have you enabled CSM and set the storage option to UEFI versus Legacy on the CSM configuration menu?

    There is really absolutely nothing to be gained by using UEFI boot mode. Have you tried installing Windows 7 with the BIOS set to Legacy mode with the NVMe drive formatted as MBR instead of GPT? Unless you need to install Windows to a drive larger than 2TB the old MBR standard works flawlessly. NVMe also works flawlessly in Legacy mode as an MBR drive.

    I think the installing media needs to be GPT too?

    Already tried it with the drive formatted to GPT for UEFI with Rufus 3.1.1 and to be sure with Rufus 1.4.1

    P751DM2:

    UEFI turned on, Secure Boot turned off:
    Errorcode: Windows failed to start. File: \EFI\Microsoft\Boot\BCD. An error occured while attempting to read the boot configuration data.

    UEFI turned off:
    Not possible to boot (Rufus built in error code as formatted for UEFI Boot only)

    I would be perfectly happy without UEFI and MBR drives. But the P751DM2 won't let me choose.
    The stock BIOS is so rudimentary that it just seems to be a joke. From what I've seen, it's impossible to choose CSM or Legacy just because there is no option to do so o_O

    There was an image out there that would not work too IIRC.

    I did have it all working on my old MSI machine but that was 7 years ago! So a bit lost to time.

    Did you had identical problems with the MSI?
    How did you solve it?

    Honestly, it can't be that hard to install an operating system! That really bugs me

    You can't install Windows 7 in UEFI mode on this system, at least as far as I know. I have the Prema BIOS and tried everything, but only legacy/MBR worked. Which is perfectly fine, been running a dual boot of Windows 7 Pro SP1 and W10 Pro 2004 (stripped using MSMG Toolkit) with no issues.

    How does the Prema Boot page look like? I'm on Stock BIOS and I can only switch UEFI on or off. Absolutely no choice for Legacy/CSM.
    If I turn off UEFI and boot from a MBR fat32 Windows 7 drive, Windows setups loads but crashes before you can choose to Install/Format the SSD. Error: BIOS not ACPI compliant.
