    No bootable OS 3FO


    My laptop suddenly crashed in the middle of a game and gave a BSOD. Upon rebooting it says that no bootable os found. 2 hours prior to this i booted to an older harddrive with an external hdd enclosure by changing uefi settings. However I made sure to revert UEFI settings back to the default. I was able to restart and boot back to my internal hdd with the external hdd enclosure disconnected. I think this is somehow connected. Any ideas how to fix this? I can still boot from the external hdd if I connect it upon powering the laptop on, but I can't boot from my internal.

    :)

    Multi-bootable USB

    Hey guys from TPU, couldn't find any specific thread pertaining to the question asked on title. As mentioned, I'm trying to create a bootable USB, but with many specifics boots available.

    I've been trying to create one with multiple boot device including one that enables me to run Windows 10 directly on the USB Thumb Drive but to no avail.

    The list of bootable images i'm trying to create are

    1. Windows 10 (A full OS running from thumb drive)
    2. Windows 10 ISO (Bootable disk image for fresh install)
    3. MemTest86+

    Have tried YUMI or UUI from the website USB PenDrive Linux but as this is my first time, i don't know how am i screwing up or am doing it right.. Anyone got a rough idea on a step by step guide? Thanks!

    No bootable OS 3FO

    Error 3FO upon startup

    Hi Gavin

    A 3FO error can sometimes indicate an imminent hard drive failure, that error is produced by the hardware test on your PC and not by Windows . . .

    Is your PC a HP system by any chance, if so this is a known bug on a HP and generally does not indicate hard drive failure . . .

    How old roughly is your PC?
