I did take Win10 boot.wim. hence boot and install completed. when reboot, my asus got passed. then finished install. Win7 run fine. but my Dell 7070 (9th gen Intel CPU) stuck at windows logo. freezing-up. I agree, the acpi.sys file not much help.I will try more *.efi files.
I tried more. now PC got boot looping. I didn't meet this issue before. looks a problem related with USB driver as mouse/keyboard got locked with Windows logo. couldn't move them any more. Their LED were on. went off when Windows logo start. my boot/install.wim are using same USB 3.0/3.1/3.2 drivers. boot/install no problem. but re-boot got freezing-up.
I was exactly using daniel_k's latest version. my asus works fine with it.HP 800 i5-8500/9500 also runs fine with it. but Dell couldn't go through reboot. failed to complete install.

Thanks Gelip, so, for my Intel CPU. The right one is USB_3x_fix2.zip than USB_3x_fixed. let me try out.

Could I ask a dumb question? Are bootmgfw.efi and boot.wim the only Win 10 files I need to transplant into my Win 7 installation media to install Win 7 with the Win 10 bootloader? The concept is I have a Win 10 machine with mixed MBR/UEFI support. I'd like to add a clean install of Win 7 (via MBR) and then run MBR2GPT so I can switch it over to a UEFI system for secure booting. My plan is that I'll keep my Win 7 and Win 10 systems on separate disks, so I can keep them independently bootable via BIOS. I prefer Win 7 for everyday use, but I don't want to throw out my Win 10 system. That's why I'm trying to get secure boot working on Win 7. No luck via installing Win 7 with Flashboot Pro. I would guess it won't secure boot because Flashboot's modified bootloader defeats the signature requirement for secure boot? Could I ask a dumb question? Do you need anything else from Win 10 other than boot.wim? Do I also need to add Win 10's bootmgfw.efi to my Win 7 installation media? Or do I need a few other files as well? I guess I also need Bootx64.efi and memtest.efi. I'm trying to figure out what I need before I begin fiddling with it.
Thanks so much! I can see that you know this, but I'm not familiar with a couple parts of your cool tech lingo. Typically Win 10 boot.wim, then Win 7 boot.wim? If we could break that down into 2 or 3 steps for a novice? This is confusing for me, because looking at the winntsetup screen in that sevens-link, I'm not sure how to slipstream the Win 10 bootloader files into my Win 7 UEFI set-up. In principle, it seems like this should be manageable. Copy a few Win 10 files into my Win 7 installation media, and then I can install Win 7 using the Win 10 bootloader. Do I access the slipstream by clicking on the Tweaks>>> button in winntsetup? To simplify this, I don't need drivers, because I'm installing Win 7 into an Optiplex 7050, which has enough native driver support to get a good result without adding any drivers. After I install Win 7, I add a Dell ethernet driver via CD. That's the only outside assistance needed to get a fully functional system on the 7050. By way of full disclosure, I'm not sure how to resolve the Int10 issue without Flashboot Pro. The 7050 has native VGA hardware, so I wonder if that means a workaround is available post-installation? Maybe the UEFI GOP can access the 7050's native VGA hardware?
