    Since the owner lounge for Spin 5 is closed, I created a new topic.

    See here how to install Win7 x64 on Acer Spin 5:
    1) General guide: https://pastebin.com/d4hN4ih0
    2) Guide only for i7-8550u CPU: https://pastebin.com/H0cWhQHH

    The guide consists in multiple solutions for each step that I gathered around the internet, I only adapted them to the needs.

    This guide includes links to all necessary files (including Win7 x64 drivers, hopefully they work with all models, I could only test on mine which is a SP515 with i7-8550u CPU).

    The main idea is simple: Acer Spin 5 has an UEFI Class 3 BIOS, which means no CSM. Windows 7's Standard VGA driver needs CSM to operate, so on a UEFI Class 3 BIOS it has to be disabled, otherwise it won't properly boot. But when you do this, you get no video during the installation, because during that the Standard VGA driver is used. Fortunately, there is a way to get video by integrating the integrated Intel graphic card driver so that the installation would automatically load it and get video output, but that happens only after the driver is loaded, so the first part of the installation will remain under black screen. The problem is that there is no official driver for UHD series on Windows 7, so the one for HD series has to be modified to be made compatible with UHD, fortunately that is possible. By modifying the inf file, you always lose the official signature and unfortunately Windows doesn't load unsigned drivers during setup. Therefore in order to get the driver loaded and get video output, the driver must be signed. Officially signing is very expensive and by unofficially signing you have to manually include the certificate into the Windows installation before it even starts to install. Luckily, that is certainly possible by integrating it via it's mounter registry. Some say that using test mode and disabling driver signing might also work, but there is too much uncertainty and something might go wrong and in the end test mode would appear everywhere. More than that, Windows 7's BCD boot files are incompatible with UEFI Class 3 BIOS, so they have to be replaced with those from Windows 10, luckily they match with each other. Finally, activating Win7 under UEFI is unusual, but made possible.

    Update: I tested a newer version of the Intel Video Driver (21.20.16.4860, older was 21.20.16.4839) and it works better, with the old one I got occasionally black screen which was actually BSOD (because of missing vga you can't see blue screens). The bastards from intel have just removed the driver from their website (original URL was: https://downloadmirror.intel.com/27360/a08/win64_15.45.23.4860.zip), but luckily there is always a backup (thanks to softpedia: https://us.softpedia-secure-downloa...0599796/drivers/video/win64_15.45.23.4860.zip). Just use the same method of editing the inf, then the 2 dll files and then signing. If you have windows already installed, you can update the driver manually in device manager with this one, if you get black screen you can force shut down and power on again, it will work. If you want to remove the old driver from the system to free up a few hundred MB, use the information from the first answer from here: https://stackoverflow.com/questions...-remove-a-device-driver-in-windows-7/27768776

    I read your posts on the other forums. So you wanted to install win7 too on uefi class 3 bios. Did you just adapted my guide to your hardware or did you do something different? I'm just curious

    well basicly as simple as this:
    win7image+drivers integrated to .iso (correct usb3+nvme+nvidia gpu) + updates up to 14.1.2020 + integrated updated installer (win10 based, see link below)
    nvidiainstallers exe filed must be unpacked and properly handled (change correct filetypes .dl_ --> .dll and so on.
    transfer your win7.iso to your winPE usb sticks 'ISOS' folder
    installed windows 7 from winPE environment
    After first boot -> power off, winPE with win7 isousb stick removal from laptop. -> put in to win10 stick and went to cmd and disabled vga and entered bcdedit commands..
    after the vga is disabled, I just waited 10minutes with black screen then windows 7 booted and window "finalizing your settings screen" appeared.

    little guide I made for myself so I would remember next time..

    Great! It's slightly different, but the basic principle is the same. Thanks for sharing!

    Tried to install Windows 7 on my asus vivobook uefi class 3 with i5-8265U a few weeks back, but that was before I saw this post. Will give it a new try with these instructions.

    No... It was way over my head... Tried but did not work, must have missed something. I do have nVidia 250MX in optimus, most probably that is the problem. Must find a Windows 7 driver for it. I really dont use the laptop since I can't stand Win10. Tried Linux but that is also not for the faint of heart.

    It has nothing to do with nvidia card, that is your 2nd video card, you install a driver for it after you have windows up an running with win7. You sure have 2 videocards showing up in device manager under windows 10, then most likely you have the intel one from the cpu and the dedicated nvidia. In this case you must get the dev/ven ids from device manager of windows 10 for the uhd video card and maybe use a different driver to integrate or modify and integrate, because the one that i used would support only kaby lake, your cpu is whiskey lake. I think you must try different drivers until you get one or ask here: https://www.win-raid.com/t4348f52-Win-x-Coffee-Like-UHD-Video-driver.html

    However this guy succeded installing win7 on his laptop which has the same cpu as yours: https://www.win-raid.com/t5807f52-Request-Need-Win-x-driver-for-Synaptics-Touchpad-SYN.html . You could ask him which driver he used and his method. Maybe his laptop has no uefi class 3 so he didn't have to disable vga and use standard vga driver, but since you have class 3 you need to properly integrate his video driver after you sign it with my method, otherwise it won't work.
