Hi all

I have an Acer V571P-6472, and I believe there's a BIOS boot error. It turns on, the Acer logo flashes and as I try to press F2/F12 (or every possible key combination I've seen) it does not work and goes to a screen that says then 


Intel UNDI. PXE-2.1 (build 003)
Copyright (c) 1997-2000 Intel Corporation

This Product is covered by one or more of the following patents: 

(insert 6 differnt patents)

Realtek PCIe GBE Family Controller Series v2. 46 (03/23/12)
PXE-E61: Media test failure, check cable

-

then goes to a screen that says

Operating System not found
_


and it remains there until you turn the computer off.

I bought a system recovery disk but it prompted me saying that it could only boot from UEFI mode. How do I do this? 

Thanks!

    that error is a classic for boot partition damage or dead HDD.

     

    UEFI can only be changed on BIOS....so probably taking off the HDD from your laptop can be a good thing to test if it works or not.

    It's not the hard drive.  I took it out and replaced it with a spare (used twice), and it booted up, went to the PXE-ROM, and then went to a screen asking me if I wanted to start it in safe mode, and when I clicked start Windows normally, it flashed across three different screens and went back to the loop.

    that error appears when BIOS doesn't find a bootable device, so it's normally related to HDD.

     

    with a bootable windows 8.x-10 USB, are you able to enter Repair PC/Troubleshoot/advanced options/UEFI firmware settings?

    Unless you took the HD out and installed it in a caddy and connected it to another PC and DiskInfo shows no errors, it is still suspect.

     

    If you have created a Recovery Disc, you can boot from the disc ->Troubleshooting -> Advanced -> Command prompt. Then give it these instructions:

     

    bootrec /fixmbr

    bootrec /fixboot

    bootrec /rebuildBCD

    exit

    Continue to boot normally.
