Chosen Solution
My computer turned off on me and whenever I try to turn it on it says boot device not found please install an operating system on your hard drive disk what do I do?
@brysonninja “no boot device found” is usually an indication of a failed hard drive or a corrupt OS. You can try and get into the BIOS of your computer by tapping away on the ESC or F10 key as soon as you power on laptop. Once you accessed the BIOS check if your computer even recognizes a HDD. If it does that change to boot order to a USB port and use a bootable USB drive to access your computer and your hard drive. You could try to reinstall the OS or if the BIOS does not recognize a HDD, replace it with a new drive and OS.
the hard drive maybe loose, take it out and then reinstall it or than that the drive could be corrupted
I had the same proplem . “boot device not found hard disk 3fo” I found the solution . The proplem was in sata cable . It was cut. It worked after i changed it
you gotta check out your HDD, pls take your hdd from location and check its electronic circuit on it, actually, mostly the problem occurs actuators connection point, pls clean it with any rubber you find and take your HDD back on pc….
I resetted my dell vostro yesterday but it is stucking on “the computer restarted unexpectedly or encountered unexpected error “ I tried to press SHIFT+F10 but still I can’t access command prompt. Today I have tried to put another windows 10 but it says Selected boot device failed but the disk boots in other devices
There is a simple trick for this to work, it took me days to find this trick out… you can send me a message on facebook (Wuan Garry)
Change the sata cable because it’s probably defective or maybe it got pinched hard if it was wrapped around other wires. Either way follow the advice Mostafa abdelbadea gave.
