Hi, I have a problem with getting windows to start up.

Around month ago I had similar problem. In the beginning on start up BSOD showed saying something about faulty hardware. After some retrys I got stuck on "automatic repair" loop. So I reinstalled Windows using bootable USB. For some weeks everything was ok but one day BSOD showed up again (saying something about faulty hardware). Only difference now is when I start up PC, it gets to loading screen part, after some time restarts and "preparing automatic repair" screen shows up after which screen gets black (but doesn't turns off).
When I try using the same bootable USB, I get to the loading screen after which (or during it) screen gets black and nothing happens...
Does anyone have idea how to repair this problem? Or how to determine which PC component is dead? ☹
 
For a simple functional test,
Run memtest86.
It boots from a usb stick and does not use windows.
You can download the free edition here:

If you can run a full pass with NO errors, your ram should be ok.

Laptops will usually have a mechanism to restore the unit to factory specs.
If you did not fully wipe the HDD in your attempt to reinstall windows. you might be able to recover.

Regardless, if memtest shows up ok, I suggest you replace the HDD with a ssd of suitable size.
You will be amazed at how much difference a ssd makes in a laptop.
A 1tb samsung 860 evo is about $120.

I suspect your problem may be a failing hard drive. Try booting your PC with the 1TB HDD disconnected to see if you can get into the BIOS.
Took out HDD and it disappeared from BIOS "SATA mode selection". Before that (with HDD in) it showed HDD with model name ST1000LM024 HN-M101MBB.

Will try memtest86, hopefully tomorrow, because I don't have another PC at home. And will consider buying ssd, thanks for advice ;) Definitely will buy external HDD, just to store important files :D

Turns out my HDD is broken. Came to this conclusion by changing my HDD to HDD of PC which already had windows installed on, and with other HDD PC turned on perfectly fine... Now I have to find a method to recover files from broken HDD, if it is even possible
