Everytime I turned on my computer it leads me to a black screen with the message of "Reboot and select proper device boot". What I am doing in order to successfully lead the booting process to windows 10 is by accessing the Boot Manager and I have to choose "Windows Boot Manager" or "launch efi shell from filesystem device" or by pressing Esc button to load default. Now i don't know how to fix this? I've been searching the internet for several days for an answer.

Note: I just installed a fresh windows 10 on my laptop and my BIOS settings are on default.

    I would suggest going into bios and setting your default boot device to wherever you installed your new windows 10. I would imagine this could be the culprit however depending on how you set everything up results may vary. Usually if everything went correctly with the install, you should only need to tell your bios where to look when it "boots" the OS which would be the installation destination. if this does not do the trick then I would try seeing if you have any "one time boot" or alternative order set up in your boot sequence. Only other possibility I would imagine is flawed install. – RickwhoPrograms Aug 15 at 16:21
  • This problem existed since before installing windows 10. I installed windows 10 using UEFI'S command prompt since my laptop cannot boot from my flash drive. The installer I used is also good , I use it before on another computer and works good. – Denzell Aug 15 at 16:36
  • Can I disable all other options on boot except my hard drive where the OS is installed? – Denzell Aug 15 at 17:01
  • i'm not sure if you would be able to do that, however in my experience when you go into bios you should see a few different options. From there find out which drive has your windows 10 installed on it, and tell bios to boot from that. I'm not sure how your laptop is set up but it should be relatively simple to figure out unless you have some sort of custom raid or virtual array's setup. If you are only looking for physical drives it should be iether A or B, and I would imagine the hard drive would have the name of the manufacturer or some coding to denote this in the bios menu ex: Toshiba XXX. – RickwhoPrograms Aug 15 at 18:11
  • @RickwhoPrograms It's a little bit more complicated than what you think if it's a new UEFI machine. You're thinking BIOS, lagacy... – GabrielaGarcia Aug 15 at 19:46

We can try the following ways to troubleshoot the issue:


  1. Set the boot order: select the correct local hard drive to boot.

  2. Turn off Secure Boot.

  3. Restart the computer to see if it can boot successfully.

If the way1 does not work, we try to reinstall operating system by our current USB flash drive.


  1. Prepare a new USB flash drive with at least 4GB of space (if our current USB flash drive needs to be used on other devices, but if we don't need it and we can format it).

  2. Download a new Win 10 1803 ISO image.

  3. Burn this ISO into a USB flash drive with Rufus tool and make this USB flash drive into UEFI boot mode.
