Hello,

I have an AN515-45 which shows no bootable device. The NVME SSD shows up in the BIOS, but does not show anything in the boot menu (which should say "Windows boot loader" if I remember correctly).

I used RUFUS to create a bootable Win 10 USB, so I could try to repair or reinstall, but it won't load - it spins for a long time, and then a BSOD - stop code: DRIVER_PNP_WATCHDOG. I've tried with secure boot both enabled and disabled. I also tried two different USB drives.

Any ideas would be appreciated.

    Have you tried to fit the M.2 boot drive into the other M.2 slot, as the AN515-45 comes with 2x M.2 slots? As your problems are very unusual and should not be happening, as and if you get "DRIVER_PNP_WATCHDOG" bsod then look and check the following:

    1. Do a HARD RESET with taking the main battery out, bios battery out and RAM and Clear CMOS Jumper (see below for the different models) then leave all these components disconnected for 30 min and reconnect and try to boot the laptop up, see if that works.
    2. See if you have actual RAM Issues: As RAM problems but if RAM is having issues in performing its operation, it can result in this bsod issue and laptops not booting up.
    3. Faulty Drivers: Device drivers communicate between the device and OS and if the device driver has become faulty then it can be the cause of this issue.
    4. If UEFI did nothing, change the BIOS to default settings.

     Clear CMOS Jumper (GN20-E3/E5/E7)

    Clear CMOS Jumper (N18P-G61/GN20-P0/P1)

    Try all the above as and if all that you have done doesn't work, then there is an internal issue that only a tech with proper tools can analyze and fix and a user like you will never ever be able to fix. Also see the included PDF guide of "Forcing a USB drive to boot from side Port"

    The first and easiest method to boot to the Troubleshoot menu is to turn on your laptop and tap the F11 key. Make sure you tap it repeatedly and that you start doing so right away, as systems tends to boot quickly, you might have to make a few attempts at booting to the troubleshoot menu.

    The ‘Boot Device Not Found’ (see this Boot Device Not Found Error (Complete Guide)" error occurs when there is an incorrect boot sequence in the BIOS setup or the system can’t detect the hard disk. Many users have reported about encountering this error under different circumstances with a different set of measures. When this issue occurs, any of the following error messages may appear on the screen:

    • Boot device not found. Please install an operating system on your hard disk
    • No boot device available
    • HP boot device not found
    • Boot device not found – hard disk (3F0)
    • No bootable device found – insert boot disk and press any key

    Hi @ddot


    You can try to reset the BIOS to check if that makes any difference.


    If you are having trouble booting your system, you may try to reset your BIOS/UEFI settings to default.

    1. Press and hold the power button for 10 seconds, or until your system shuts completely down.
    2. Power on the system. ...
    3. Press F9 and then Enter to load the default configuration.
    4. Press F10 and then Enter to save and exit.


    If that doesn't work then you can try to do a reset to check if that makes any difference.



    NOTE: Make sure to backup all the data before the reset.


    Hope it will help you in some way.

    F11 does nothing, resetting the BIOS does nothing, reseating the drive didn't help. I can't use a recovery environment because it won't boot off the Win 10 USB (DRIVER_PNP_WATCHDOG BSOD).

    Is the boot drive an m.2 (as a spinner hdd is very prone to failure) and even m.2 drives can go wrong and their circuitries can fail, so check the m.2 drive out put this m.2 drive into the 2nd ssd m.2 slot of your AN515-45 and see if the drive is recognised and the laptop boots, as its impossible to not be able to get a working drive to boot after going through all the steps that I've given from the  Boot Device Not Found Error (Complete Guide). Otherwise, your bios at Advanced >Storage drive configuration which has these functions is set wrongly:

    1. Enter to configure storage device port enable/disable (such as SATA/PCIE storage device port).
    2. Only visible if system set to AHCI

    Or your laptops internal m.2 ports solid state drives (SSD) that are part of the internal circuit boards that embed flash memory chips and controllers on the motherboard have a problem, which needs to be diagnosed by an experienced technician, as no matter what you do a user like you can't fix.

    @StevenGen The boot drive is m2. I can't get a USB to boot to try to repair it, hence I cannot go through all the steps. At this point I don't even care if the m2 is dead, but I can't boot a Windows install USB to try to repair or reinstall Windows on a new one.

    Power button reset? Nope

    Reset the drive? Nope

    Reset BIOS? Nope

    Boot PC with bootable media? Nope - DRIVER_PNP_WATCHDOG blue screen.

    Someone somewhere said try F11 on boot - nope. Also ALT+F10 - nope.

    I have tried multiple ways to boot off of two different Win 10 USBs - UEFI with and without secure boot - nope. I found somewhere the BIOS hotkey CTRL+S to be able to switch from SATA to AHCI - nope - after the switch to AHCI now all I get is a black screen with no Acer logo and no BIOS access. I've tried to reset the BIOS by clearing the CMOS and still black screen with no BIOS.

    @StevenGen I did the hard reset as suggested (except I saw no CMOS jumper on mine) and am able to access the BIOS again - thanks!

    The m.2 showed in the BIOS in either slot, but would not boot. I bought an external m.2 enclosure to test the drive on my desktop, and it would not show up in drive management. It would seem it is dead.

    But, I can now boot from a Win 10 USB (no more DRIVER_PNP_WATCHDOG blue screen) by trying it without the m.2 in the laptop at all (maybe I should have thought of that). From searching around, that particular stop code appears to be mostly related to bad or missing SATA drivers... I'm guessing it was trying to mount or access the m.2 when booting from the USB and couldn't so it BSOD'd; I took it out entirely and it booted right up from the USB.

    I am now going to buy a new m.2 NVME and with any luck won't have any trouble installing Windows on it.

    I hope if someone else runs into this issue this thread will be of assistance; note that I did not haver to change any BIOS settings from default to boot from USB (like I had seen on various help videos I found). My model number is AN515-45-5812.

    Thanks for your help @StevenGen
