    BOOTMGR is missing. Press Ctrl Alt Del to restart


    Hi

    I have an Asus PC running W864, I have a Seagate 2 TB Harddrive and I have two 2TB Hard drive connected by USB.

    Sometimes when I leave my PC running while doing other things I come back to it after a few hours and the PC is showing a black screen the message
    "BOOTMGR is missing. Press Ctrl Alt Del to restart" This happens about once or twice a month, I can see no pattern or event that triggers it.

    When I press Ctrl Alt Del the PC restarts and comes back to the same message.

    If I reboot to a bootable repair disk or Windows 8 install disk my OS and Hard drive are not found, but my USB connected drives are.

    I have to turn of my PC completely, I take out the plug, and switch it back on, sometimes it reboots properly to the Start screen but sometimes it just goes back to the black screen with the BOOTMGR is missing. Press Ctrl Alt Del to restart message.

    What seems to work always is if I turn off the 2 USB attached drives turn off the PC then restart, that works 100% of the time as far as I can recall.

    I suspect my had drive is faulty but I have taken the PC to the supplier and their tests show all is okay, even when I run Seatools for Windows it checks out 100%.

    Seatools for DOS does not find the Harddrive, I believe this is a W7/8 issue.

    I have repaired the BOOTMGR using the process shown here,
    How to fix bootmgr is missing in Windows 8
    But since W8 disk found the Harddrive I suspect the PC would have booted okay anyway.

    Active SMART says it is okay and Event Viewer in W8 does not show any related errors.

    I would appreciate any feedback or advice, I suspect the Harddrive is faulty but do not know how to really test it.

    Regards

    Daniel

    Your external USB dock is probably setup as the primary boot device in the bios, you should change that by default.

    You can always boot from it if you have to by pressing (f11 or f12) during boot up ( read your bios boot prompt when booting )

    What may be causing this is your system rebooting either by a call to reboot, minor crash, or a necessary windows update rebooting your system..

    You can either change your bios setting to change your primary boot device to your internal harddrive, or you can leave the USB dock powered off unless you are using it ( also a good practice to extend life of HDD ).

    Hi, thanks for your reply.

    I do not believe my external USB Harddrive is set up as the bootable drive, my bios boot sequence is set up to CD then hard drive.

    Unless there is some other issue I am missing, if the USB Harddrive were set up as the primary boot drive wouldn't
    the boot sequence fail because there is no OS on either external drive. Also wouldn't there be an issue every time I booted instead of it happening intermittently?

    What could be calling for a reboot? I have no automatic updates running on my PC, even Windows Update is set to manual only, it doesn't even check for updates, I do that weekly.

    Cheers

    Happens often when you have a removable storage device plugged in the computer and you start your system.
    Try setting your BIOS settings to accomodate the boot sequence properly.

    It depends which starts first, your internal or external drive, sometimes your external may start slower than the internal..

    Hi

    before I make any changes I need to understand why the problem would occur when the PC has been on for hours, and booted
    to the correct drive.

    Something is making it reboot and because Event Viewer shows no issues I suspect is a catastrophic event.

    Any ideas on that?

    Thanks

    Back in the day when I had a Compaq from 1998 this started happening to me just as you described when the hard drive started failing. Eventually no matter how hard I tried the system would not boot. Can you try running this program and posting a screenshot of your drive(s) as they appear there?

    As long as your internal drive starts up first there will be no problem, but i suspect once in a while its your external drive that starts first..

    There can be 2 boot options that can conflict..

    1: boot order priority

    2: Boot from add-on card first

    what model is your asus and do you have an add-on card for your external drives?

    Hi

    that is what I suspect is happening here but need some evidence so I can get the problem fixed.

    The screenshot is attached.
