    [Downgrade W10 to W7] Windows 7 won't boot

    Hello Tenforum users,

    I have been trying to replace pre-installed Windows 10 to Windows 7 x64 in UEFI (Secure boot disabled) on my girlfriend lap Acer V15 V3-575G-50W2. Bios version is 1.10.
    I almost have lost my sanity with such a task (why should be so difficult to install another OS?)

    As I wrote earlier, I wan't to install W7 in UEFI - so far I have successfully booted W7 x64 USB device, formatted Primary Partition (no other partitions were modified or formatted), the installation was almost made, just one restart was needed at the end of installation as usually. After the restart, the "Starting Windows" screen appeared, but it frozed almost immediately.

    I'm running out of ideas now - I'm completely clueless and have no idea, what to search for...

    Thanks for any usefull advice ^^

    Why do you want to downgrade a laptop that came from the factory with Windows 10 and does not have factory support for Windows 7 down to Windows 7?

    Hello NavyLCDR,
    thank you for your reply.

    If it depends on me, I would buy new laptop without OS or with Win7, but at the time there was only this option.
    She needs to run some SW and stuff that currently don't work on Win 10.

    I hope this thread will not gonna twist into W10 promo. We have decided to install W7 on it and maybe later, when the W10 grows up a bit, upgrade to W10.

    At the moment, Im looking for a way, how to boot W7 correctly. (or reason, why isn't it booting correctly)

    What I would recommend is to run Windows 7 in a virtual machine hosted by Windows 10. It sounds like the laptop has hardware that is no longer compatible with Windows 7. The virtual machine "layer" will take care of the hardware compatibility. I love installing operating systems and making them work - that's why I am in the Windows 10 insider program and I have Beta tested Windows all the way back to Windows 95. For fun I tried installing Windows 7 on a desktop computer I built from scratch about 4 months ago. I got so frustrated trying to make the new hardware work with Windows 7 that even I gave up on that project and in my playing and testing I install Windows once/week on average.

    Although it does require Windows 10 Pro.

    Also, though, your question would better be asked at since you are trying to install Windows 7.
