the pop-up window reads:

 

"WARNING! Please boot this Recovery Disc using legacy BIOS mode"

Please boot this Recovery Disc using legacy BIOS mode"

 

when I switch it to Legacy BIOS, then the pop-up window reads:

 

"WARNING! Please boot this Recovery Disc using UEFI BIOS mode"

 

I have tried secure boot enabled and disabled.

 

Ugh, what do I do to restore my computer?  I don't have Recovery on my PC.  It was lost with the WIN8.1 upgrade. 

 

Acer Aspire v5-571p

    i suggest you to create a bootable USB or CD media from Hiren's boot cd .iso
    http://www.hirensbootcd.org/download/
    unzip the zip file, burn the .iso file to CD or USB pen/external HDD
    then boot from the burned media and choose mini-xp from the options, once in the desktop, double click "command prompt"

    then type
    diskpart
    then on diskpart type
    list disk
    take note of the correct disk ID to erase
    type
    select disk x
    (x is the ID of your HDD to erase)
    type
    clean
    type exit

    shutdown Mini Xp


    now boot from your recovery media using UEFI and secure boot enabled

    I'm not an Acer employee.

    I received this message when I tried the above.

     

    virtual disk service error: clean is not allowed on the disk containing the current boot, system, pagefile, crashdump, or hibernation volume

     

    I only have one hard drive.

     

    thanks!
