Windows 7 can be installed on pure UEFI (no CSM), but you need to remove standard vga driver from it. You will get black screen during de installation. You will have to integrate drivers for your videocard into the installation so that you will have video output at the end of the installation, otherwise you'll still get black screen. This is the most difficult part because nowadays you have videocards with no driver for win7,such as intel uhd 620/630, but luckily sometimes (also for uhd 620/630) you can use modified drivers. Keep in mind that a modified driver loses it's signature and such a nonsigned driver won't be loaded during the installation of windows. Therefore you might need to create a custom certificate and sign the modified driver with it and the import it into the registry of the installation to make it work.

Using information from various discussions and discoveries of other users, I created a step by step guide for my Acer Spin 5 laptop: Guide - How to install Windows 7 x64 on Acer Spin 5 laptop | NotebookReview

You can also check my discussion with another user who managed to make it work on his Acer Nitro laptop: windows 7 install issues - Boot from USB / Boot anywhere - reboot.pro

Depending on your cpu and/or integrated video card (uhd 620/630), you can use 2 drivers:
1) for uhd 620 and some 630 make it yourself using the guide provided in the 2 topics.
2) for some uhd 630 for which the previous driver fails, use this driver as is directly (without modofying anything), you might however only need to sign it with your custom certificate as in the guide: Forum - RE: Win 7 x64 Coffee Like UHD 630 Video driver - 2

Good luck!

LE: You can use my slimmed version of win7 x64 to test, it installs very fast. Includes all updates until March 2019: Win7SP1IE11x64Mar2019_Lite.iso - Google Drive

I put the USB in, went to the boot menu, and tried to boot from it, but it just booted it from legacy and gave me an infinite flashing white _ in the top left corner.

You need to install windows 7 using dism and wim file, everything running from an win10 uefi running from an usb stick. Then you have to remove legacy vga, which will give you black screen during the installation and you only get video IF you have the videodriver slipstreamed into the installation.

If you don't disable vga you get loop with orb or video artifacts and freeze. If you don't slipstream the video driver you will get black screen forever.

What cpu and video card do you have?

Below an extract for you from my guide about how to do everything EXCEPT the video driver. Remember you need two usb sticks for this or copy all the necesarry files on the same stick with bootable win10pe:


I) Preparing the bootable Mini Windows 10 UEFI USB.

A) For this, you need an USB stick that will get formated to GPT format (you will lose all current data on it) so that it will boot on UEFI.

B) Download "Medicat Mini Windows 10 NAKED" ISO from here: mini.windows.10.NAKED.iso - Google Drive

C) Download "ISO2Disc" application from here: 410 Gone and install it.

D) Insert the USB stick, check which drive letter it gets, then run "ISO2Disc", browse for the "Medicat Mini Windows 10 NAKED" ISO file, then select "Burn fo USB Flash Drive", verify that the correct drive letter of the USB stick and the size is correctly chosen, if not, choose the correct USB, then select "Partition Style" as "GPT" and click "Start Burn".


II) Preparing the Windows 7 installation files on a second USB stick/external HDD/secondary HDD on the target computer

A) Extract the Windows 7 x64 "install.wim" from any Windows 7 x64 ISO of your choice.

1) Use any ISO file viewer and open any Windows 7 x64 ISO of your choice.

2) Extract "install.wim" from the "sources" folder within the ISO file to the second USB stick/external HDD/secondary HDD on the target computer.


B) Download "Unlocker" application from here: 410 Gone and copy it to the second USB stick/external HDD/secondary HDD on the target computer.


C) Copy the "bootmgfw.efi" to the second USB stick/external HDD/secondary HDD on the target computer.

1) If you have access to a Windows 10 installation, you find the file here "C:\Windows\Boot\EFI\bootmgfw.efi".

2) If you don't have access to a Windows 10 installation, you have to extract "sources\install.wim" from the ISO image of any Windows 10 installation kit, then open the "install.wim" with 7-Zip and you will find the file here: "\1\Windows\Boot\EFI\bootmgfw.efi".


III) Installing Windows 7 x64 procedure on the target computer

A) Boot the target computer from the created bootable Mini Windows 10 UEFI USB.

B) Partition the install HDD/SSD using diskpart from an elevated (run as administrator) "Command Prompt" window, remember to backup all data first, this will delete everything, using the following commands (where N is your choice for the install HDD/SSD, be careful when choosing):
list disk
select disk N
clean
convert gpt
create partition efi size=100
format quick fs=fat32
assign letter="S"
create partition primary
format quick fs=ntfs
assign letter="W"
exit

C) Let's assume that your second USB stick/external HDD/secondary HDD on the target computer (where you have already copied all the necessary files) has the "Z" drive letter, so just replace the "Z" drive letter in all the following commands with the one of your particular case.


D) Install Windows 7 x64 using DISM and apply EFI boot partition from the installation

1) Apply the "install.wim" image from your second USB stick/external HDD/secondary HDD on the target computer to the "W" partition you created earlier, using the following command entered in an elevated (Run as administrator) "Command prompt" window:
DISM.exe /Apply-Image /ImageFile:Z:\install.wim /Index:1 /ApplyDir:W:\

2) After the process is completed, apply EFI boot partition from the installation, using the following command entered in an elevated (Run as administrator) "Command prompt" window:
BCDboot.exe W:\Windows /s S:


E) Install the modified and signed Intel UHD driver from your second USB stick/external HDD/secondary HDD on the target computer to the "W" partition you created earlier, using the following command entered in an elevated (Run as administrator) "Command prompt" window:
dism /Image:W:\ /Add-Driver /Driver:Z:\Intel /Recurse /forceunsigned

F) Disable the legacy vga (which is incompatible with UEFI) from the registry of the installed Windows 7 from the "W" partition you created earlier, using the following commands entered line by line in an elevated (Run as administrator) "Command prompt" window:
set Services=HKLM\loaded_SYSTEM\ControlSet001\Services
reg.exe load HKLM\loaded_SYSTEM W:\Windows\system32\config\system
reg.exe add "%Services%\Vga" /f /t REG_DWORD /v "Start" /d 4
reg.exe add "%Services%\VgaSave" /f /t REG_DWORD /v "Start" /d 4
reg.exe unload HKLM\loaded_SYSTEM


G) Delete legacy vga driver file (which is incomaptible with UEFI) completely from the installed Windows 7 from the "W" partition you created earlier

1) Install "Unlocker" by running "Unlocker1.9.2.exe" from your second USB stick/external HDD/secondary HDD on the target computer.

2) Using "Windows Explorer", go to "W:\Windows\system32\driver" and look for "vga.sys", right-click on it, and choose "Unlocker". A window appears and under "No action" menu, choose "Delete" and then click "OK". Check manually that the file is deleted. You have to use this method, because you can't normally delete "vga.sys" due to security permissions of the installation.


H) Using "Windows Explorer", copy "bootmgfw.efi" from your second USB stick/external HDD/secondary HDD on the target computer to the following path: "S:\EFI\Microsoft\Boot", overwriting the already existing file.

I) Disable legacy vga (which is incompatible with UEFI) from the EFI boot, using the following commands entered line by line in an elevated (Run as administrator) "Command prompt" window:
bcdedit /store "s:\efi\microsoft\boot\bcd" /set {default} bootlog yes
bcdedit /store "s:\efi\microsoft\boot\bcd" /set {default} bootstatuspolicy IgnoreAllFailures
bcdedit /store "s:\efi\microsoft\boot\bcd" /set {default} novesa on
bcdedit /store "s:\efi\microsoft\boot\bcd" /set {default} quietboot on

@Ten20 : Greets,

1. I assume that now you have the untouched M$ Win 7 SP 1 ISO.

2. I will suggest to prepare the UEFI+GPT Installation media afresh with
Rufus - Create bootable USB drives the easy way

Rufus will format the pen drive. So, if there is any important data on the pen drive, copy it to a safe place.

(i) Insert the pen drive.
(ii) Launch Rufus & follow the Image & instructions :

How do I install Windows 7 on a GPT disk with UEFI enabled in my bios?-capture.png

(iii) Select the pen drive in the Device menu.
(iv) Click SELECT, browse to the win 7 sp1 iso and double click it.

If the win 7 SP 1 Iso is selected, It will show under Boot selection ( Marked as blue in the Image ).

Please don't get confused by the win 7 edition's name appeared in the Image. Just make sure the win 7 is mentioned there some way!

(v) Choose Partition scheme as GPT & Target system as UEFI.

( it may pick them automatically but make sure the two are selected as GPT & UEFI! )

(vi) need not change any thing else.
(vii) press START & be patient till it shows as READY.
(viii) close the Rufus window. it's done!

3. I will suggest to not to make any installation right now. Just try to boot into the UEFI+GPT installation media & Check whether you go ahead of Start windows.

At first, just try to boot into it with UEFI enabled in the BIOS.
If it hangs at Start from there, switch to UEFI & Legacy setting in BIOS & try to boot in it again.


Let me know.

Thanks & Regards. ...

All installation disks has all versions (Home, HP,Pro and Ultimate)
On your USB installation drive, go to sources\ei.cfg and rename it.
During installation it will ask what version you want to install (of course you must have the Key version)

One is here : Direct Download Link: Ultimate SP1 x64

2. This version will support Ultimate by default but if you need other versions, you have to open up them as mentioned by Megahertz07 Sir.

OR
If you tell the required version Pro, HP, etc.,, we can directly provide you the link for that version.

( Don't go for Installation right now! )

Let us know.

Thanks & Regards. ...
