    Brought over from other thread you started.

    DBAN may not like your hardware if it wonít boot. I was going to suggest the below as it would be the preferable method but for some reason, I thought it would be more complicated for you.

    My brain doesnít work right sometimes:)

    Boot from a windows 10 installation drive

    Press shift+f10 to get to command prompt

    Type

    diskpart

    list disk

    select disk n (n is number of drive to be wiped - normally 0 if only 1 drive)

    clean all (all does secure wipe - can take a long time - do overnight)

    exit

    exit

    Drive is now wiped securely.

    What exactly does this mean: "Boot from a windows 10 installation drive"? In other words, am I right in believing that the DBAN CD is okay as it is (with just the files I've enumerated) and that the CD should be in the CD drive? Also, what should the boot sequence be in the BIOS? Do I want Windows Boot Manager first or the CD/DVD drive?

    Installation drive is the disc or flash drive that you have the windows install media loaded on using the media creation tool.

    Boot sequence is just the order the PC looks to boot from. If you set it to boot from a CD first, the PC will look for a bootable disc in the drive and boot from it if possible. If the disc isnít bootable or there isnít anything in the CD drive, itíll skip and move on to whatever is next in line. You can have them in whatever order you prefer but if youíre going to install Windows, either the CD drive or USB boot needs to be moved up to be checked BEFORE the hard drive in the sequence.

    According to the Acer forum thread discussed earlier, pressing F12 after power up will let you pick where to boot from without changing the boot order in the BIOS.

    I set the boot order in the BIOS back to Windows Boot Mgr, followed by CD/DVD and saved the settings. Then I kept tapping F12 but it just booted into Windows again; I didn't get any menu that let me boot from the CD where DBAN is installed.

    This is getting REALLY exasperating. I *think* I am following directions but for all the posts I've made, I *still* haven't got DBAN to erase the hard drive so that I can reinstall Windows, let alone gotten as far as actually starting the reinstall.

    What did you create the Windows Installation media on A DVD disc or a flash drive?

    Let's get you booted into the installation media and proceed from there. Forget DBAN at this time. If we can get you into the OS installation, we can erase the hard drive from there.


    * I got these instructions from another Acer forum thread regarding a different model Acer. They may/may not help you*





    UEFI

    The Windows 8 desktop computer has a UEFI with a legacy BIOS mode. By default DVDs, CDs, and USB devices cannot be booted from, like most computers with a BIOS.
    When a Live-CD was inserted into the DVD drive, and a Live-USB was inserted into a USB port they were ignored and the computer booted straight into Windows 8. The UEFI settings needed to be changed and the computer was rebooted.
    The boot screen displayed:

    • Press <Del> to enter setup

    After pressing the Delete key the BIOS menu appeared. The DVD drive was shown as the ď2nd Boot DeviceĒ. As a result, the boot priority order was altered and ďCD&DVDĒ was configured to be the ď1st Boot DeviceĒ. The computer was rebooted, and again the Live-DVD was ignored.
    Further configurations were required.
    Automatically Boot from CD/DVD

    To get the Acer AXC-605-ER30 to boot first from the DVD drive, do the following:

    1. Press Delete to enter the BIOS setup
    2. Under the Authentication tab, disable Secure Boot
    3. Under the Boot Options tab, set Launch CSM to Always
    4. Under the Boot Options tab, set 1st Boot Device to CD&DVD
    5. Under the Boot Options tab, enable Boot Menu
    6. Save the changes and exit

    The AXC-605-ER30 will now first attempt to boot from the DVD drive. Moreover, if the boot menu is accessed (F12), the DVD drive, hard drive, and USB drives (if detected), will appear as boot options.
    With Compatibility Support Module (CSM) set to always, hard drives, CDs/DVDs and USB devices will boot in a legacy BIOS compatibility mode.

    The HDD is potentially compromised, so the built-in restore functions canít be trusted.
    You're very right. No recent backup should be trusted.

    When I owned my shop we would never use system restore, or recent backups. I also very seldom ever saw people backup there files, no matter how much we said backup. Also remember if you're going to start from scratch, once you get your drivers and anti virus installed, now is a good time to create a base image in case you ever need to start over again. And remember to verify your backups. Acronis is great backup software and can do many other things besides backing up.

    Sorry for the delay in responding; I needed to take some time away from this. In answer to your question about creating the installation media, I haven't even started that yet. I had planned to get the DBAN going first, then create the media while DBAN did its thing, which I understand might be many hours. But if you'd saying to make the media first then I'll go work on that. I haven't read the tutorial for that yet but I'll do that and then either proceed to create the media or, more likely, post here again with any question that arise as I read the tutorial. I'll stay in this thread to avoid confusing things further.

    I doubt my brother has taken a backup in his life - on this or any other computer ;-)

    Do you have any local friends that are experienced in working with PCs that could possibly help you along and assist with interpreting the info you're given?

    When youíre first getting your feet wet in PC repair, learning from people helping you on the net doesnít always cut it. Iím not great at explaining things. Also, Iím not an expert by any means so keep that in mind. You never stop learning when it comes to PCs.

    Youíre fortunate in this situation because you have a PC that doesnít require any backup and presumably youíre not on a strict time table. Just relax and take it slow.

    If youíre still unable to get DBAN going, perhaps itís best to put that aside and concentrate on getting the Windows 10 install media created. Once youíve created that, review the instructions for booting that I posted above and see if you can get into the installation setup.
