HI!!!

I managed to do the flashing of the BIOS, here is how I did it:

On a separate computer:

I downloaded the latest bios upgrade from Acer Support Download Center. The zip file contained an executable which I couldn´t run directly from the Symantec System Recovery Disk

Using winrar I extracted the contents to a pen drive

I also downloaded Symantec System Recovery Disk 2013 (SSRD) trial image (you need to register to be able to download it) and burn it into a CD

 

With my laptop I then boot into the SSRD (before switching to legacy mode I had set the DVD unit as the first option)

Then within Analyze tab you can open a command prompt and run the bios upgrade files (in this case one named launch.bat)

It then flashed the Bios and when finished it restarted to EFI!!!:smileyvery-happy:

Re: How to boot back to EUFI from Legacy BIOS, pressing F2 getting "Operating System not found&

Hi  I'm new to the forum.  Last night I changed my BIOS from EUFI to Legacy BIOS (not knowing the impact).  The F2 doesn't work.  And I can't find any BIOS firmware files for my Aspire V5-471P on the Acer Support Page.  Is there another Acer Support Download Center somewhere else?

I messed up last night by changing the EUFI from Legacy BIOS not knowing the impact. As you know, the F2 will not bring up the BIOS screen.  The OS (Win 8.1 64-bit) is not found.  From what I read, I will need to flash the BIOS with the original or the most current firmware file copy.  But I can't find a BIOS file for my Aspire V5-471P on the Acer support page.  Can you step me through the process?  Many thanks.  (I'm not a hacker or PC experimenter but taught PC courses a few years ago at a local college.)
