    Win 10 x64

    Potential Solution 'No bootable device detected' after fresh install

    Hello Forum,

    My Dell Precision T3600 originally came with Win7 x64 which I upgraded to Win10 successfully. However I wanted to do a fresh install of Win10 to get rid of accumulated OS mess that cluttered most of my 256GB SSD drive. So I created a bootable USB thanks to MS create media tool. From the bootable Windows 10 setup, I deleted the old partitions (OEM recovery and such which was taking almost 1GB) selected the new clean primary partition and installed Win10. All was looking good until after install it rebooted and got a 'No bootable device detected' error. I will spare you the hell I went through to find the following simple solution:

    In the BIOS, you need to change the boot sequence type from 'Legacy' (you know, the old one since forever which you put diskette above HD) to the new fancy UEFI which apparently is a new industry standard where everything is taken care of by the devices. Here's a screenshot of my BIOS:

    After this BIOS change, restart the computer with the bootable Windows 10 installation, when the setup shows the available partitions, I had a little warning beside mine saying it couldn't install windows on that partition. I deleted it and then I could install it. Rebooted and everything was perfectly fine.

    Hopefully this will help someone save some time.

    Also the screenshot was taken after everything was working. When I originally set it, there was no 'Windows boot manager' and SCSI HD there. It seems UEFI let's OSes write to the BIOS or something.

    Thanks for posting. So basically it's just a matter of setting the BIOS to UEFI instead of Legacy prior to running Windows installer? I've been trying to solve this same issue for several weeks and would think that in one of my many attempts to install, the BIOS would have been set the way you suggested. I'll give it a shot and report back.
