    W10 machine won't boot ("Reboot and Select proper Boot device" error)


    I've been changing a disk on my Shuttle PC (SZ68R5) and when I turned it back on, I get the "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device" error message. My system boots from a Kingston SUV500MS mSATA SSD drive which is screwed to the motherboard and I haven't touched as part of this work. I've checked the BIOS and the boot order is still correct and the Kingston SUV500MS drive still shows in the SATA config page.


    I then created a Windows 10 installation media on a USB stick and booted from this. I followed the "Repair your computer" -> Troubleshoot -> Start-up Repair and it reported that it was unable to repair my PC.


    What diagnostic / fix steps should I apply now?


    Thanks in anticipation...

    :)

    "reboot and select proper boot device" after fresh install

    I understand your logic.
    But that is not what is happening.
    See.

    It simply won't go.

    On the other hand, if I take this path... brings me to W10 from where I'm posting *Smile

  3. Reboot and Select Proper Boot Device...after reboot?

    Hello all. Getting a little frustrated here. A couple of weeks ago we had a user come in on a Monday morning to find that her pc was displaying the classic message "Reboot and select proper boot device...". Tried popping in a windows disk and fixing the MBR, no luck. Ended up reinstalling windows and her few programs back on it. All was good after this. For about a day. She came in the next day to find the same message. So at that point we decided that more than likely the drive was bad even though oddly enough it tested out fine. It was a Corsair 60gb SSD.

    Last week we swapped that Corsair with a 64gb Crucial SSD and installed Windows. We then created a backup image of that drive. All was good until Thursday when her power strip that the PC was plugged into got tripped. Start up the computer for find "Reboot and select proper boot device..." message. So, apply the backed up image to the SSD since repairing the MBR didn't work.

    Now this morning she comes in and the PC is running fine. Attempts to open Microsoft Word and she gets a pop-up stating there isn't enough disk space. So, she then restarts and upon booting back up gets "Reboot and select proper boot device..."

    Any ideas what is causing this? Is it something with the mobo or do I just have horrible luck and replaced the bad SSD with another bad SSD?

    reboot and select proper boot device

    Alright whenever I try and boot to my SSD (boot drive) my computer will end up saying "reboot and select proper boot device or insert boot media in selected boot device and press a key". However if I use the same SATA and power connections and attach my Linux hard drive, with no changes to the BIOS, it will boot just fine. If I have my SSD set up as a slave drive, I can access the files fine and browse the drive as if nothing is wrong. Anyone know why this is happening?

    Specs:
    Mobo: ASUS M4A79XTD evo
    CPU: AMD Phenom II X4 965
    RAM: 2x(2x 2GB A-Data Gaming Series)
    SSD1: Kingston SSDNow 64GB
    SSD2: OCZ Onyx 32GB
    HDD: WD Caviar Black 640GB
    Linux HDD: Hitachi Deskstar 320GB
    DVD Drive: Some LiteON drive
    Graphics card: AMD Radeon HD 6950

    If anyone has an idea as to why this is happening, please let me know. The system has been working fine up until I took it apart earlier to clean it out.
