    Re: Wiping Data from Hard Drive

    Can you find any entry in the BIOS menus about

    - system configuration
    - boot mode
    - UEFI or
    - secure boot or
    - fast boot?

    I can only found these from the following:
    Secure Boot: Enabled
    Fast Boot: Enabled

    You are getting this from the BIOS? If not, try one of these options at boot:

    * Press the F1, F10, or F11 key after restarting the computer.
    * HP Tablet PCs may use F10 or F12.
    * Other HP computers may allow access to BIOS using the F2 or Esc keys.

    Please search once more if you can find something that might switch UEFI mode on/off!

    If there is no such menu entry, you'll have to live with UEFI, and you should keep the UEFI partition that is already there. Install Ubuntu and use the methods described in the following links to make it work (if it does not work at once). It is usually easier to make Ubuntu work with

    Secure Boot: Disabled
    Fast Boot: Disabled

    Re: Wiping Data from Hard Drive

    Even if converting to BIOS/CSM boot, I would stay with gpt partitioning and leave an efi partition at beginning of drive. You then could later convert to UEFI if desired. If you use MBR(msdos) partitioning you would have to totally reformat drive to gpt if you ever wanted to convert.
    With gpt partitioning:
    Ubuntu will boot in BIOS mode if you have a 1MB unformatted partition with the bios_grub flag.
    Ubuntu or Windows will boot in UEFI mode from the efi partition which is formatted FAT32 and has boot flag.
    You can have both an efi and bios_grub partition on the gpt partitioned drive.

    Some computers have modified UEFI to only boot the Windows folder and/or the Windows efi file. Boot-Repair converts grub2's shim to be that file for those computers, so if yours is one of those and you use UEFI you may need the Windows efi file. Boot-Repair does rename this file to actually be grub2's shim file.
    /EFI/Microsoft/Boot/bootmgfw.efi

    Is it that to disable UEFI?
    When I go to Storage > Boot Order, I found the following:
    UEFI Boot Sources
    - ubuntu
    - Windows Boot Manager
    - USB Floppy/CD
    - USB Hard Drive
    - UEFI: IPv4 Realtek PCIe GBE Family Controller
    - UEFI: IPv6 Realtek PCIe GBE Family Controller
    Legacy Boot Sources : Disabled

    If I enabled Legacy Boot Sources, does it mean that everything will be fine and it disabled UEFI?

    I can leave that, but the problem is that I can't even boot to Windows 8, there is always an error (Your PC ran into a problem) and then it takes me back to grub!
