Boot Hang at Windows Logo - White horizontal lines on top screen

Yes, i can boot, the screen is stuck at the Windows Logo with "Starting Windows" quote.

Sequence : I boot, then windows logo loads (rotating colors etc.) then hangs but distortion lines move on top of screen, then i press Ctrl-Alt-Del and after that i can hear the login sound of Windows and have full keyboard access to do anything i want.....

...without seeing anything....


My installation USB Media is UEFI, as for the NVme driver, as far as i remember i used the "Load Driver" option while selecting partitions to see the NVme drive.

I do not want to do a repair, i would like to try a System Restore to a rrestore point that takes me 4-5 days ago, that i did not have this problem.

I have used the application Shadow Explorer to access my restore points and i see that i have several ones before the day of the incident. Maybe restoring to one of them saves my system.
My question is if the Windows 8 UEFI installation media can be used to restore my Win 7 system to a saved restore point.
According to this guy here, it can be done :

I have a UEFI install...Same problem, My Win Rescue disk could not be read by EUFI boot (but the disk contains a UFI file).

SCENARIO: Changed my Virtual Memory Partition location, restarted (while at the same time plugging in an external SATA Drive), then rebooted into.. NOTHING!

Windows recovery CD disc I made to recover a System backup image FAILS to run when choosing load disk in UEFI.

Tried the Win 7 install disk restore in UEFI and that was totaly useless.

After 2 days of attempts in DOS COMMANDS programming and research I gave up and was about to install the new Win 8 Dev disc to a new OS from scratch... then I was SAVED! In Win 8 Dev disc loadup I chose Repair and chose Restore Win 7 and it auto restored my Win 7 OS. It could not have been fully restored from my hardisk System backup image, as the restore process only took about 30 sec and my files were current. Must have just restored the EFI system partition (ESP) boot records.

Obviously Win 7 Install Disc is not setup very well for UEFI services. Please fix. Good to see Win 8 is more optimised for UEFI.
So My first Impression of a Win 8 experience is... WOW!!

SOLUTION... Win 8 Dev disc in UEFI... choose Repair > Win 7

The other option i thought of was to do a repair install from inside Windows....but with pressing keys blind...That way, a repair install keeps my programs, files and settings but refreshes my system.
After my system boots (with just showing the stuck logo on screen), i will plug my installation USB and press the correct key sequence to initiate the repair install (i believe this is done with the ''Upgrade'' option.

I will give feedback, if you have any other thoughts, i would like to hear.

Win 8 installation disk may have USB3 drivers but not the NVme driver.
I think it wont be able to see the SM 950 Pro.
You can try a Win 10 installation disk.
But I would follow my tutorial and add the Sata, USB 3 and the NVme driver to the Win 7 installation disk.

Thank you for all of your effort and time spent !

I really appreciate it !

I am waiting for my last files to copy from my M.2 drive to the slower-than-death HDD and then i will try 3-4 times including your options.

Since it's about 1:00 after midnight here, i will stop my trials after the above and if unsuccessful, tomorrow i will clean install Win7.

Well,

Since i tried everything with the M.2 installation of Windows 7 (every USB i made from my Windows 7 ISO - NTLite, Win7USB3.0, NVMe Fix - failed) i figured out i should use a normal SATA III SSD, in my case a spare 850 EVO 2.5".

I thought that it must be the NVMe drive that hangs the installation, so i did not give up, and imaged my "corrupt" M.2 Windows 7 installation onto the 2.5" SATA drive.

I am now speaking while my machine is live using that "corrupt" Windows 7 image from my M.2.

Drivers were a mess (Intel VGA, Realtek Audio) so i installed the known-to-work versions again.

One problem is that the system restore did not work (error 0x8007007B) because of a second C: drive that was marked as "missing" so i fixed that by turning off the system restore in this "weird" missing drive.

When i finish with that, i will plug again the M.2 drive as a secondary, install the latest nvme drivers from Samsung, create an image of this installation and pass it on to the M.2 drive, to see if it will boot.

I will revert with feedback for this messy situation.

Thank you again for your help.

Well, everything went ok!

I am now booting fine from my M.2 drive in my rescued Win7 UEFI installation.

Only thing happening is the white distorted lines if i have simultaneously connected the HDD with the Win10 installation as secondary drive.

I can bypass this image by pressing Ctrl-Alt-Del.

I think i will open a case with Lenovo Support to see if this is some sort of UEFI glitch.
