So I have a problem, my Laptop is Hanging on the boot screen at 75%.

 

Windows upgraded to windows 10 then rolled back to 7 tried to restart and that's when the problem started.

 

DETAILS:

 

At the boot screen the laptop is unresponsive:

Pressing any of the F-Keys does nothing.

Pressing CTRL ALT DEL resets the laptop with the same problem.

the progress bar is stuck at 75%

No audiable beeps are heard on turn on.

The Bios shows the Phoenix logo in the bottom right corner

 

Methods of recovery tried:

I have used a 4gb usb pen and the CrisDisk program to make a recovery disk

I have used all the BIOS downloads available on the acer support website for my Laptop model

I have Formatted the Pen drive then using the CRISDISK I have create the dos disk, I then unplugged it andplugged it back in and runt he crisdisk again as advised I then moved my Bios to the pen drive and renamed it BIOS.WPH

I put the pen drive into the laptop with out a power plug or battery  in, inserted the power while holding FN+ESC and powered on the laptop, the screen is black and the USB shows activity for 5 seconds then stops, the laptop does not restart. after 30 minutes manually restarting the laptop takes me back to the Frozen boot screen.

 

I have tried using the bios with its original downloaded name and changing it to BIOS.wph

 

Nothing is working! Am I naming the bios wrong? am I creating the disk incorrectly I am at a loose end 

 

P;ease someone help me!
