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!

    Download 

    BIOSAcerBIOS1.247.8 MB2012/12/26Download

    Extract it to a new folder on desktop.

    Make a new clean Crisis usb drive.

    Delete the WPH file on the USB.

    Open the bios file in the new folder and click the DOS file.

    rename  JE40124.WPH to BIOS.WPH and paste into the USB.

    You should now have MINIDOS.SYS, PHLASH16.EXE, and BIOS.WPH in the Crisis disk.

     

    "

    1. Remove the battery from the laptop and unplug the AC power cord. Then, plug in your USB floppy drive (with the CRISIS Recovery Disk in it and ready to go). Next, with the AC still unplugged, press and hold the Fn (Function) and B buttons. While still holding them, plug the AC power in, then press the power button.
    2. The system should power on, but there should be no LEDs lit up, and the fan should not slow down like it normally does. If that is not what happens, and you get LEDs that light up, and the fan slows like normal, unplug the AC power and try using the Win and B keys instead. Once the system has booted into the BIOS recovery mode, the floppy light will flash as it reads the BIOS file from the disk. You can then release the Fn+B keys (orWin+B). After a minute or two, the floppy light will stop flashing.
    3. DO NOT shut the computer off, as the process is only half complete. The system is now flashing the BIOS.
    4. After the USB or floppy light goes off, leave the computer on for two or three minutes; more if you want to be sure, and if the system does not reboot itself (mine did not), unplug the AC power. I let mine go for five minutes or so and pulled the plug (the power button would not shut the system off no matter how long I held it; I suspect this is normal). Five minutes should be plenty; however long you wait, try to be patient. My five minutes of waiting seemed to take forever, but paid off."

    Read this a few times before you start so, you don't miss anything

     Good Luck

    Thank you for replying, but I have tried all the standard methods using CrisisDisk, everyone has a slightly different guide of how to do it.

     

    Is it possible that the crisis disk is not working?

    If so What is my next option?

    I was fearing this was the case I am still holding out hope that someone may have another option I could try.

    I think you have tried about all there is to try when it comes to flashing the bios.
