BIOS Update Failed - Windows Will NOT Load (HP Pavilion DV7)(Vista Home Prem. 64-bit)

HP Pavilion DV7-1135nr
Microsoft Windows Vista (64-bit)

System:

HP Pavilion DV7-1135nr

Windows Vista Home Premium SP2 (64 bit)

 

Problem:

I was having problems with the Wifi not working, which is common with this system according to other threads.  One of the forums suggested updating the BIOS.  The original version was F.48.  I located and downloaded the latest version, F.49, from the HP help page, which is an EXE file.  I ran this,  The Wifi button changed from orange to blue and was working.  When done with the laptop, the lid was closed, which put the computer into sleep mode.  The next morning, the lid was opened and the computer was working as normal, however, the Wifi button was orange and would not go back to blue.  After walking away from the laptop and coming back, I received a DOS screen stating:

 

 

Windows Boot Manager

 

Windows failed to start. A recent hardware or software change might be the cause.  To fix the problem:

1.  Insert your Windows installation disc and restart your computer.

2.  Choose your language settings, and then click "Next."

3.  Click "Repair your computer."

 

If you do not have this disc, contact your system administrator or copmuter manufacturer for assistance.

 

File:  \Windows\system32\winload.exe

 

Status:  0xc0000225

 

Info:  The selected entry could not be loaded because the application is missing or corrupt.

 

Steps Taken:

I tried using a friend's Vista Home Premium SP2 CD.  It does boot into a windows-type environment and offers to install Windows, but it does not give an option to "Repair your computer."

 

I  tried loading into Safe Mode, but it keeps putting me back into the Install Windows screen.

 

Thinking Windows itself may have gone bad, I mirrored the SSD and stored it away, formatted the SSD, and then installed a prior mirror of the drive, which was  functional when it was creasted.  I started the computer and again get the "Windows Boot Manager" info listed above in italics.

 

I tried locating a valid copy of the previous BIOS, F.48, without success.  I then downloaded F.49 again, thinking the original install was corrupted somehow.

 

Request:

1)  Can someone tell me a way to install/update the BIOS without being in Windows?  It says it needs a Windows environment to work, which I obviously do not have.

 

2)  Can someone help  me find BIOS F.48 for my system, preferrably one that does not need to be installed in a Windows environment?
