Had a successful bios upgrade but now the PC wont start. Plus loud fan.

HP Recommended
HP Compaq 8200 Elite Convertible Minitower
Microsoft Windows 10 (64-bit)

 I got a notification of an upgrade available for my PC. I put the bios upgrade files on a usb stick. I restarted and pressed F10 and went to the Bios. I had version 2.10 from 2011. I chose the option to flash the new bios. It completed and said it was successful.

 

I pressed a button to restart. It went back to the os which is Windows 10 64bit. Everything was fine but I wanted to know if the bios looked any different so I restarted and kept pressing F10 to get to the bios. Instead of going to the bios it just went back to windows. I restarted again, I heard some people say pressing delete gets you to the bios, I figured maybe the key changed since the bios was new but instead of going to the bios it just gave a black screen.

 

Then I tried to restart without going to the bios but it never went past the black screen, I let it stay on the black screen and after a few minutes the fan gets extremely loud. Now im stuck on it not going past the black screen and getting a loud fan. It started when I booted while pressing delete.

1st Please try a Hard Reset
This is valid for most notebooks, and some desktops.
Press and Hold the PWR off button for 4 seconds to force a PWR off.
Unplug from the wall.
IF you see a battery compartment door, then your computer has a removable battery.

IF NOT then you do not have a removable battery.

Remove any removable battery.
Press and hold the power button for 15 seconds to complete the reset.

(Re-insert any battery you removed).

Hi

Could you please expand on the

MAKE, MODEL, OS and SKU?

WinKey + R and type msinfo32 then look at line 9 for the SKU.

 

 

https://support.hp.com/us-en/document/c02693833

Turn off the notebook.
Plug the notebook into a power source using the power adapter.
With the notebook off, press and hold the Windows logo key and the B key at the same time (WinKey +B).

NB: On some notebook models, it might be necessary to press and hold the Windows logo key and the V key (WinKey +V).

While pressing those keys, press and hold the Power button on the computer for 2 to 3 seconds, and then release the Power button but continue to hold the Windows logo key and the B or V key until the HP BIOS update screen displays or you hear a beeping sound (usually 8 beeps).

 

 

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…
(You will need a NON_OEM key for W7);
W8.x and W10 should activate automagically from their embedded licence key.
https://www.microsoft.com/en-us/software-download/windows7
https://www.microsoft.com/en-us/software-download/windows8
https://www.microsoft.com/en-us/software-download/windows10

For when it’s a NON MS OS ( iOS / Linux ) creating the install media.
www.microsoft.com/en-us/software-download/windows10ISO

A 3rd party site is (Courtesy of @CherylG)...
http://getintopc.com/softwares/operating-systems/windows-7-home-premium-free-download-iso-32-bit-64-...

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:- W7 Try running a Startup Repair more than once for a full fix.
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

If the above FAILS then please try:-
http://www.thewindowsclub.com/repair-master-boot-record-mbr-windows
http://www.thewindowsclub.com/install-windows-7-from-usb
http://www.thewindowsclub.com/install-windows-10-from-usb

 

You may need to change the Secure/Legacy  boot option, and the boot sequence also.
