Win7 suddenly starts off with blue-screen boot manager

    Win7 suddenly starts off with blue-screen boot manager

    First of all, my laptop has 2 working USB ports.
    I don't like typing with the built-in keyboard (and the touchpad) so I always connect a USB keyboard and mouse.

    Yesterday (11-Aug), I unplugged the keyboard to use my USB HDD (to transfer files).
    When I clicked the Windows ribbon, suddenly square-brackets were typed in non-stop, as if the physical key was held down.
    I had to log it off and restart the computer (after safely removed the USB HDD).

    Then, in the start-up screen where it used to display 'Press <F2 > to enter SETUP' now changed to 'Prepare to boot OS'.
    This automatically proceeds to the blue-background Boot Manager (that's what it only says at the top) which has the following choices (simplified):
    1. boot via HDD (the local C with the OS)
    2. boot via CD/DVD
    3. network boot

    There's no timeout here, so I picked HDD booting, which now boots into the Windows Logo as it would normally.
    After logging in, no other keys (both built-in and USB keyboard) respond except the built-in keyboard Windows key.
    Once I pressed that, the problem (square brackets) disappears, for the current session.

    The above change in booting also renamed the booting OS from 'Windows 7 Ultimate' to 'Windows 7 Ultimate (recovered)'.
    The following are copied from the EasyBCD program:


    There is one entry in the Windows bootloader.
    Default: Windows 7 Ultimate (recovered)
    Timeout: 30 seconds
    EasyBCD Boot Device: C:\Entry #1
    Name: Windows 7 Ultimate (recovered)
    BCD ID: {default}
    Drive: C:\
    Bootloader Path: \Windows\system32\winload.exe

    osdevice partition=C:
    systemroot \Windows
    resumeobject {881221ce-4e52-11e1-845e-806e6f6e6963}


    I'm thinking (in the future) of making a bootable USB using the EasyBCD to do the System Repair (I don't even know if that'll fix it), but I wonder what causes all of this.

    (additional info)
    Also, when I set to Skip the Boot via EasyBCD, the Boot Manager still persists.
    And if I added a new Win7 boot entry (making it default and moved it up), skipping the boot will hang at the Windows Logo screen (but without the logo), along with non-stop beepings.
    Luckily, after spamming DOWN arrowkey, I managed to boot normally and reverted the EasyBCD changes.
    For now, I'll have to put up with the annoying booting than mess up the computer making it worse.

    Today (14-Aug), I found out that the squarebracket problem reappears within the same log session.
    I also just realised that the physical key of the opening square bracket (and inevitably, the curly one) doesn't work at all.
    The last time I used the laptop keyboard was about a year ago, and without any issue.
    I had to psuedo-disable the key with AutoHotKey, and put it in the Start folder:
    #SingleInstance force
    SetBatchLines -1
    ListLines Off
    I just couldn't find any explanation as to why pressing the Windows key of the laptop works (albeit, temporarily).

    I think the auto-spam of the bracket during booting might be the cause of the booting issue.
    Or perhaps, it's a completely independent issue.

    I forgot to mention in the first post that I also did the sfc/ SCANNOW which results in no integrity issue.
    I did it again today to make sure.

    Using the PrtSc key? Is that possible at the boot screen? I'll try tomorrow.

    I found a similar screenshot (mine has HDD as #1, and of course, the blue background):
    Looks like he has the same booting issue as me.

    Forgive me, it's actually the exact same boot screen (white-blue Boot Manager as opposed to black-white Windows Boot Manager)
