Hi. I have an almost three year old Asus GL552V, with no problems so far, except for a screen replacement I had to make last week due to an accident with the screen. Barely used it for the last year because it became a spare laptop then.

BIOS version: 300
Intel(R) Core (TM) i7-77 @ 2.80GHZ
Total Memory: 12288 MB
Intel(R) HD Graphics 630

I was playing some light novel games and folded it for sleep mode, and when I opened it again, it was turned off. Turning it on, it said "Undoing changes made to your computer." From here on out, I rebooted it with the turn off--turn on--turn off--turn on--turn off, then turn on, method, and now I only get a black screen after the Asus logo. There seems to be a window that's attempting to come out (only the box outline shows), but it ultimately doesn't show, and the laptop just tries to reboot again. This is a loop until I just force shut down the whole thing.

When I try to press escape on the Asus logo, a window shows up:

Please select boot device:
Windows Boot Manager (P2: XXX)
Enter Setup

When I try Windows Boot Manager, the same loop with the failed window happens. When I Enter Setup, it leads me to BIOS Utility.

What do I do to fix this? I'm guessing the window that fails to open is the key to it rebooting successfully, so what do I need to do? What could have possibly happened/what have I done to the laptop that led to this? Would appreciate any leads.

I assume you mean you have this CPU - https://ark.intel.com/content/www/us/en/ark/products/97185/intel-core-i7-7700hq-processor-6m-cache-up-to-3-80-ghz.html although that laptop model only shows as 6700HQ
your Intel HD graphics mentioned would match a 7700HQ

okay, can find some of that model with 7700hq.

Undoing changes made to your computer.
sounds to me like windows tried to do a version update and it didn't succeed and its broken windows trying to roll back.

Do you have a win 10 installer? If not, on another PC, download the Windows 10 media creation tool and use it to make a win 10 installer on USB

how to boot off USB
You can also refer to the step-by-step tutorial.

1.Once you enter the BIOS configuration, enter [Security] -> disable [Secure Boot Control].

2. Select [BOOT], enable [Launch CSM]. [Compatibility Support Module], and disable [Fast Boot].

3. Press F10 to save the configuration.

4. You can boot the system from USB drive/CD-ROM by following the two methods.

(1) Enter BIOS -> Select [Save & Exit] -> Select USB drive/CD-ROM from [Boot Override]

(2) Hold and press [ESC] then press the power button to turn on the system. You can select the boot device from the list.

is there anything on PC you want to save?
boot from installer
on screen after languages, choose repair this pc, not install.
choose troubleshoot
choose advanced
choose command prompt
type notepad and press enter
in notepad, select file>open
Use file explorer to copy any files you need to save to USB or hdd

Once you copied everything off laptop, I would do a clean install
boot from installer
