I have an Aspire M5 that is not bootable.  I ordered and received recovery discs from Acer.  When I boot using UEFI mode, I get the following error message... "Please boot this Recover Disc uusing legacy BIOS mode."  When I boot using legacy BIOS mode, I get this error message... "Restore Fail: This recovery system can only be used on "UEFI" mode.  Please press "OK" to restart the system immediately."  I attached screen shots of both.  My guess is something else is wrong that a recovery disc can't fix.  Any thoughts or suggestions on how to proceed?  Thanks!1-0001.gif2-0000.gif

    you need to completly wipe your HDD before restoring your PC.

     

    are you able to reach windows command prompt? (try to press shift+F10 keys at that screen)

    if so, try this:

    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

     

    if not, you can create a bootable USB or CD (boot under legacy) with gparted that will jelp you erase your HDD:

    Thank you for the suggestion. I was unable to bring up a command prompt, so I'll try gparted.
