    "Reboot and select proper boot device"


    I just had a major BSOD with my 64-bit system, and it said it was collecting data and would then reboot. It said the error was related to netio.sys.

    When my PC rebooted, all I got was "Reboot and select proper boot device". It was like my OS wasn't there any more. I even plugged in my Windows 10 OS install thumb drive, and selected startup repair, and it said it couldn't repair the system. As a last resort, I tried hitting F12 at boot to bring up my boot menu, and then selected the Windows Boot Manager listed at the top of the menu, and it immediately booted okay. I ran sfc /scannow and chkdsk and both found no problems. No viruses according to Avast and Malwarebytes. This is the 2nd time this happened - the first time was back near the beginning of the year. All I was doing was watching an online video in Firefox when my OS crashed. Last time earlier this year I was watching a video in MPC-HC.

    I have no idea why I'm getting these crashes, and I have no idea why I have to manually select the windows boot manager now to boot. I never had to do that before tonight's crash. What happened to make me have to hit F12 and go into the boot manager now to boot? Is something corrupted relating to booting up? I tried shutting down and rebooting and now it's the same every time - I have to hit F12 to manually select the boot manager. Any help with figuring out what's up with booting would be much appreciated.

    :)

    Hello,

    On a working computer, create an Installation media of Windows 10 that allows you to repair existing Windows Installation.

    https://www.tenforums.com/tutorials/2376-create...

    Click Repair your computer at the first screen that says Install now.

    Select Startup repair and see if the computer can boot afterwards.

    Reboot and select proper boot device

    Last night I restored my computer to a January 1st 2018 version becauss I was getting the “infinate loop error” where my computer would have that buffer circle and then just go to a black screen. Now, after I’ve restored it, My Asus republic of gamers laptop
    with windows 10 says “reboot and select proper boot device.” I followed a previous form’s steps and got to the bios menu and tried setting the boot to my hard drive, but no hard drive option shows up. What should I do next?

    Do you have more than disk on your PC?

    Something must have happened to affect how my system boots.

    Try this link for the free version of Macrium Reflect: Macrium Software | Your Image is Everything. I use it on all 8 of my current physical PCs. Works like a champ!
    --Ed--

    PS: just went to check and it turns out that Version 7 for Reflect Free was released yesterday. Now updating all of my PCs. Yippee!!

    Do you have more than hard disk or SSD?
    Disconnect all other disks apart from the boot disk and then reboot, that fixes it for me
    You can then reconnect all other disks and all will be well

    I think he is saying to unplug all but the OS drive and turn the PC back on.Just unplug the sata data cable while PC is off.

    Oh, I tried that and nothing changed.

    Thanks for the link to Macrium free, EdTittel. Though the repair boot option still did nothing for me. It re-wrote the boot files but that didn't solve my issue.

    Here's what I figured out -

    In my BIOS, my boot order was :

    1) DVD drive
    2) Windows Boot Manager
    3) OS drive

    I don't remember now if that's the way it has been previously, or if the OS crash somehow changed the order. But when booting, I found that the BIOS was trying to boot from the DVD drive as expected, but since there was nothing in the drive, instead of moving on to #2 (the boot manager), it was just saying there was no OS present since the DVD drive was empty. It was like there was no 2nd or 3rd boot option after the DVD drive, but there was.

    Is this normal? On my old ASUS motherboards, I remember setting the DVD drives as the first boot option in case I had any recovery media or Linux OS discs in the drives, and if the drives were empty, it would just move on to the 2nd boot option, etc.

    On my current PC with a Gigabyte Gaming 7 board, it doesn't seem to get past the first boot option if it's empty. I figured this out when I put the Macrium recovery disc in the DVD drive and the PC booted from it no problem. And since I was able to boot ok as long as I hit F12 and manually select the Windows Boot Manager, I decided to try moving the Windows Boot Manager to boot option #1 in my BIOS, and sure enough, now it boots right up when I start my PC.

    So why wasn't my BIOS just moving on to option #2 when it was seeing that my DVD drives were empty? Is this how it's supposed to be (that doesn't make sense), or is there something else in the BIOS that I might be overlooking? I can't remember now - maybe before the OS crash my BIOS did have the boot manager in the first boot option and it got re-arranged? Any ideas?
