    Using that software the VM was able to use the ISO as a bootable image. Im going to create a USB stick of the image and see if it boots on the physical machine. I made two ISOs, since I have no idea what the question was asking in whatever (french?) language it was. Give me an hour, more or less, and I'll let you know the results.

    Thanks for your help.

    The installer hangs here when booting:

    anthe other ISO created, the one I answered YES for...whatever the question was asking...UEFI does not recognize a bootable operating system.

    This is where I've hit a roadblock before. In windows 8.1, I was able to use the DISM command listed in the first post to install via that method. it would completely freeze when normal boot, while in safe mode freeze at disk.sys/classpnp.sys. trying to boot directly into the installer from UEFI had these results.

    1. Did you integrate the emmc drivers into boot.wim image 2 ?

    2. In addition does the bios have csm support ?

    It is asking if you want it to support efi boot in addition to bios boot . It only asks if it finds efisys.bin which is needed for efiboot.

    Both images contain the updated drivers, as well as the USB 3.0 drivers in your signature and additional eMMC/USB drivers from intel and sumsung. I'm a bit tired to give it a try today, but tomorrow I'll make an 8.1 VM and see if usng the new images makes a difference using the cmd line DISM from the first post. DISM in win 7 doesn't support the commands necessary, forwhatever reason.

    then invert what I said - the "Yes" image boots but freezes at boot, the "No" is not recognized as bootable. I'm in the process of setting up the 8.1 VM, I'll let you know what the result of the DISM process is, if it still hangs at disk.sys/classpnp.sys with the drivers included in the image.

    Wanted to update you - I did a bit of a tour yesterday: I tried installing both windows 10 and windows 11, both from USB (in case its relevant, I only have one USB port), and from an SD card. Neither would boot past the "A media driver is missing" error that occurs right after booting into the installer. I've looked through these forums and through google, and there does not seem to be any singularity solution to the issue, and none of the answers I tried resolved it. Windows 7 with the slipstreamed drivers also did not work.

    Given that I've been able to install Win8.1 onto my hard drive, and given that you seem to know much more about this than I do, do you think there would be any benefit to having Win 10 or 11 installed via the same DISM method, and then grabbing whatever generic Microsoft drivers the newer operating systems use and slipstreaming THOSE into a win7 image? Win 8.1, while it installed, was hellishly bugged, and as far as I understand - and correct me if I am wrong on this point - after the switch to x64, generic microsoft drivers are interchangeable between 7/8/10/11

    Thanks again

    I doubt win 8 or win10 drivers will work on win7. There are some win 8 drivers that have been specially modified by enthusiasts to install on win7, but only for nvme and usb3 and network cards as far as I know.

    OK. so back to step 2. here's where I'm at:

    The Windows 7 installer with added drivers fails to load entirely on boot. It freezes at the "windows is loading files" picture I posted before. Meanwhile, 8.1 and 10 installers have the same problem when booting directly to the USB bootable thumb drive: they all will not go further than the media driver is missing error: windows a media driver is missing - Brave Search . As I said before, I had windows 8.1 installed directly to the eMMC drive (it was partitioned, half the drive being ubuntu half being 8.1) through the DISM instructions included in the first post, and it booted without issue, although I had to use an external wifi adapter, mouse, and other peripherals. In trying the same method for windows 7 while in 8.1, the DISM above, I inadvertently completely borked the boot manager and had to start from scratch, reinstalling Ubuntu. Windows 10 was released after eMMC and flash memory became commonplace, so I can't venturea guess as to why that version would have the same (seemingly...after a good amount of research, there are many different causes of that error unique to different hardware profiles.) driver error as 8.1.

    Ubuntu 22.04 runs fine. Well, its ubuntu, so half the stuff doesn't work, and the instructions to fix it end up making everything worse than it was to begin with. But I think you get the point. It boots, the drivers load, and I can get work done on it. All three versions of windows install without issue into a VM. From the VM, I was able to use the DISM command within the windows 10 instance to create the typical windows file structure:

    Windows 7 disk.sys/classpnp.sys hang safe mode-image.png


    I don't have the windows boot manager installed, nor am I sure how I did it before with windows 8.1. I would wager a guess, and I'm not a betting man, that if I had a working windows boot manager it would boot. I don't see why 8.1 would work and 10 wouldn't. I'm currently searching the bowels of google to see if there is a way to take the base windows file structure above and slap the windows boot manager onto the partition (or well, onto the drive onto a separate boot partition, but again, given that you seem to know a lot about this stuff, I think you know what I mean).

    Being able to have a booting version of windows would make all of this much easier than having to continuously switch in and out of ubuntu, and in and out of VMs.

    Up date! with the help of some nice folks at the tenforums, I have been able to rebuild the windows boot partition on my secondary drive, and boot into WIN 10. It runs into an error during the initial setup, which I think I will have fixed tomorrow (the wifi here is captive, you have to log into to use it, which cannot be done during the initial windows setup.).

    Once I have a working windows instance I will come back to this primary problem. Thanks again!

    it seems I have misplaced my mouse - the trackpack on my chromebook does not work in the windows installers or in the OS proper, so I'm going to have to take a break until the 4th of next month when I can buy a new one. be back then.

    Just Ef Why Eye, I have decided to boot into a linux distribution with a low resource display environment, allowing ~2 GB of RAM to be used for a Windows 7 VM. Allocating half the devices RAM to linux and half to Windows seems to resolve the main problem I was having, of one or the other continually crashing. I had tried to see if installing to an external USB hard drive that had a SATA bridge would do the trick, as it would sidestep the eMMC/flash drive issue, and I was still coming up short.

    In any case, the 7 VM works nearly perfectly, and 8.1 when I had it booting ran...not well. I can only imagine if I did get 7 to boot, the effort involved in getting the basics to function would probably defeat the small benefits of running natively instead of virtually.

    Thanks for your help though, hopefully this can be useful to someone else in the future trying to do something similar.
