How to Uninstall and Reinstall Windows 10 when laptop doesn't load?

[Hristo993]

Okay, I've had this error many times before, called HP Support and they've worked like a charm in getting me through it. Thing is, my cocky self thinks it'll never happen again, never take the time to jot down the steps they tell me, only to pay the price. So I'll ask here, so i can simply refer back.

So basically here's what happened, the dreaded boot loop. I've ran a system check (the F2) and everything is fine, my hard disk drive isn't damaged or anything (as in the previous times). I tried the F11, however, it doesn't take me to the blue screen where I can do a factory reset. When I called HP Support, they had me do other things than the F11 solution.

When I press F11, it just keeps me on the black "Please Wait.............." screen, and doesn't go anywhere from there.

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

From 2016 onwards there is a possible recovery option via the cloud...
HP Consumer PCs - Using the HP Cloud Recovery Tool (Windows 7 & 10)

OR
This First part only works when a valid Recovery Partition is enabled.

If it displays an error message then move onto the Second part,
OR if you have data you wish to try and save using the XCOPY command.
Then create your own Repair/Recovery/Rebuild/Re-install media or buy a set from HP.

Turn off the computer.

Disconnect all connected devices and cables, Media Drives, USB drives, printers, & faxes.
Remove media from internal drives, and remove any recently added internal hardware.
Do not disconnect the monitor, keyboard, mouse, or power cord.

Turn on the computer and repeatedly press the F11 key, about once every second,
until the Choose an option screen is displayed, and then continue.

On the Choose an Option screen, click Troubleshoot, and work your way through the screens.

Second Part:-
This may require another PC. Find and Download your .iso from…
W10 should activate automagically from the embedded licence key.
https://www.microsoft.com/en-us/software-download/windows10

Expand/Extract/Burn the iso Image onto a DVD/USB as needed.
Microsoft’s Creator Tool will make the required DVD or USB.

Even though it has NO actual HP software/drivers included, you may be able to
XCOPY the C:\Users\* area onto a ‘large’ USB stick, via the Command Prompt.

You’ll need to try various drive letters; D:..-..Z: until it’s matched - could be G; mine’s S:

C:\>XCOPY C:\Users\* S:\ /e /i /h (then files like those 3 listed below get copied over)

C:\Users\desktop.ini
C:\Users\All Users\agent.1509128044.bdinstall.bin
C:\Users\All Users\HP Deskjet 2540 series\Help\flash\zoom.swf

Then you can try System Recovery Options / Advanced Options shown in the screenshots.
NB: - W10 Begin with the Automatic Repair, then Startup Settings etc.

From either the C:\ or the X:\ prompt try the following

cd boot
bootrec /FixMBR
bootrec /FixBoot
bootrec /RebuildBCD
