      No, don't change MsBridge or any other key (other than those listed in the post) and try to boot your computer from the hard disk.

    Hi,
    I am trying to boot my old ssd with Windows 7 (important stuff inside) with my laptop with Windows 10.
    Does the above way works?

    Wow! Will this still work on new ASUS ROG MB? The tech says Win 7 will not work on a new MB, but I've got years of software installed that I rely on heavily and can't easily replace. Just why do these registry entries need replacing and does the OS still work on the old MB? I read also that the DSIM command dism /image:C:\ /add-driver /driver:X:\ /recurse should work as well, but I'll have a lot of time and money invested before discovering that porting Win 7 to the new MB will work – or NOT! THANKS for any advice you can give.

      If the new mobo supports UEFI, disable the 'UEFI Support" and the 'Secure Boot' in BIOS settings. Additionally, make sure (from the motherboard manufacturer) that the motherboard supports the installed Operating System.

        The uefi and secure boots are disabled, the motherboard support windows 7, the values are 0, but the system restarts at boot… :(

    My old laptop broke and it had a disk in it with Win8 and a lot of data.
    Will this method work if I plug that disk into another laptop? That other laptop is running on Win7 but I would rather use my old disk with Win8.
    What should I do?

      The Z390 AORUS MASTER doesn't have drivers for Windows 7. You have to upgrade to Windows 10.

      @nick lai: What is the error code of the BSOD? In BIOS set the SATA mode to IDE. If it is already "IDE" then change to AHCI. Also disable the Secure Boot.

        November 15, 2018 @ 1:38 pm

        that's too fast, it reboots in a quarter of second, i can only recognize a long string made of zeros under 3 or 4 lines of words.
        secure boot is disabled and IDE should be correct, tried AHCI too but nothing.
        other ideas?
        thanks a lot for the fast reply

            i filmed it and catched the frame showing the error, it is :

            SOLVED:
            here is how, in case someone else need it:
            i downloaded all the motherboard's drivers and put them (unzipped) on a USB stick; then i used the Windows repair disk to access the command prompt and connected the usb stick; then i wrote and entered this command :
            dism /image:C:\ /add-driver /driver:X:\ /recurse

            (change C if you have Windows installed on another drive / change X with the letter of the Usb drive containing the drivers)

            at the end of the process , restarting, the PC will finally boot correctly

            thanks for your time!

    Thank you the tip! It worked 50%-t for me. Me and my daughter used different PC-s. I use a Dell Optiplex 760, my daughter Lenovo 57e. Because she went studying and only occasonally uses her PC, I decided to change the two HDD because her HDD is larger then my one. We use Windows 7 Prof. and similar programs. After saving (and deleting from the HDD-s) I changed the two disks after making your tips (the registry changes). My PC (the Dell) booted with the Lenovo's HDD (with the Windows 7), but the Lenovo does not boot with the Dell HDD (saying: STOP: 0x0000007B with blue screen). I have to install everything on the Lenovo?

    I am not sure if it is active yet but It would be life saver if you help with my scenario.
    My Dell laptop's motherboard got fried just after 1 year and 2 days after warranty expiry so I had to buy a new motherboard which I luckily found in New condition. It is dell latitude e5570 and the original CPU was a core I7 quad core with AMD GPU but this new one got core I7 dual core and intel GPU. My SSD from old computer contains windows 10 pro and I don't have any DVD for it nor optical drive in my laptop. shall i be able to use that SSD with windows on my new motherboard? Your response will be really appreciated.

        I checked the cable itself looks fine, checked setting in bios they are set to IDE.Since i am using the older ide cable to connect it to the board. Was wondering if it could be registry key i changed to 0 should i set them back to 1 now since the windows has installed the motherboard drivers. Also as i stated when i start it from being shut off , bios doesnt see the hard drive on the first boot , but when i hit ctrl alt delete to restart , loads fine. Or can it be a faulty ide cable. Stumped!

    This is really too complicated. I replaced two mother boards with Windows 10 Pro. Nothing like this was done. Just turned on the computer, and Windows 10 took care of everything. With the first computer which was done six months ago, it took thirty minutes, today it took maybe twenty minutes.

    I've had this website open on my phone for months lol. I finally got around to installing a new gigabyte Z170X-gaming 7 motherboard and i7 6700K CPU, and used this method.

    I have two RAID 1 setups (one for OS and one for Storage), and performed the first method above. Upon restarting my computer, windows wouldn't boot. I tried windows repair, but it took forever and was not making any progress (i left it for about a half hour).

    I got into the BIOS and reconfigured my RAID 1 setups (from AHCI, or whatever single drive mode it was in), and windows started and ran with no issues. I used the driver CD that came with the motherboard to get all drivers back (ethernet, etc.).

    So far so good, thanks for this writeup! It saved me a lot of time.

    Just be aware that you have to reconfigure RAID if you had it before, otherwise windows will not boot up.
