    In your case, the Win8.1 was originally factory-installed under a Microsoft license to ACER and embedded on the mainboard. That's why you can still re-install Win8.1 without paying another licensing fee. Jack E/NJ

    Then make a backup copy of your current legacy BIOS MBR-partitioned Win10 and change back to UEFI BIOS mode.  Then re-install W10 in UEFI mode on as suggested earlier https://community.acer.com/en/discussion/comment/574629/#Comment_574629 Unlike older BIOS, the newer UEFI bootstrap depends on reading a trusted EFI file on a hidden HDD partiition before it will complete its function.  Jack E/NJ

    i used the following script to create the proper gpt partitions.  rather than use an image i started fresh with a new install of windows

    rem == CreatePartitions-UEFI.txt ==
    rem == These commands are used with DiskPart to
    rem    create four partitions
    rem    for a UEFI/GPT-based PC.
    rem    Adjust the partition sizes to fill the drive
    rem    as necessary. ==
    select disk 0
    clean
    convert gpt
    rem == 1. System partition =========================
    create partition efi size=100
    rem    ** NOTE: For Advanced Format 4Kn drives,
    rem               change this value to size = 260 ** 
    format quick fs=fat32 label="System"
    assign letter="S"
    rem == 2. Microsoft Reserved (MSR) partition =======
    create partition msr size=16
    rem == 3. Windows partition ========================
    rem ==    a. Create the Windows partition ==========
    create partition primary 
    rem ==    b. Create space for the recovery tools ===
    shrink minimum=500
    rem       ** NOTE: Update this size to match the
    rem                size of the recovery tools 
    rem                (winre.wim) plus free space                   **
    rem ==    c. Prepare the Windows partition ========= 
    format quick fs=ntfs label="Windows"
    assign letter="W"
    rem === 4. Recovery tools partition ================
    create partition primary
    format quick fs=ntfs label="Recovery tools"
    assign letter="R"
    set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"
    gpt attributes=0x8000000000000001
    list volume
    exit

    this script came from microsofts site.  when i went into bios to change from legacy to uefi mode saved and exited  it wouldnt boot.  just blinking cursor.  so i went back into bios and it was set to legacy again.  so i tried clearing the passwords first then changing legacy to uefi.  again  it failed to boot.  just blinking cursor.  so i booted to a winpe disk and changed the gpt to mbr and it booted fine.  so as it stands the drive is partitioned properly, has a hidden fat 32 efi partition and windows 10 was used to remake the efi files. but the bios absolutely will not allow me to remove the password , change to efi mode, or flash the bios to a newer version

    So at this point a wiped HDD was GPT-partitioned NTFS-formatted. But it didn't boot. So WinPE was used to re-partition it to MBR. And then it booted? What operating system should the HDD have booted to when it was GPT partitioned? Jack E/NJ

    That's not what I meant. The script suggests that diskpart was used to clean, GPT-partition and NTFS-format the HDD. Which is fine. And changing to UEFI bootstrapper is fine. At this point, I only would have expected it to boot into a blinking cursor and go no further. Just as you reported earlier. Jack E/NJ
