I've been having this issue for a few days now, ever since my laptop had a bit of a fall. When I would try booting up, it tells me no boot device is found, and it seems to be a common issue that doesn't get answered. I tried checking the hard drive and swapping it out but the same problem occurred, however when i ran diagnostics after swapping, it didn't detect an issue, while before it told me the boot device was not installed.
I need help on this issue, all of the support pages are literally just talking me in circles.
Run the extended - not just the quick - diagnostics on the hard drive. F12 at powerup -- let the diagnostics run, and then boot to the 32-bit environment and run an extended test on the drive. You'll likely find bad sectors - meaning the drive needs to be replaced.
After you installed the new drive, you tried to boot into the Windows 10 Installation Media ?
Also, is the new drive detected in the BIOS ? It should be listed under the main tab and by Fixed HDD?
Dell Inspiron 3543, windows 10:
How about under boot tab ? UEFI and Secure boot are enable? Do you see Windows Boot Manager and the two Onboard NIC?
What type of cell phone is it ? You're able to get into the BIOS ? By the way, what the exact Dell model number and version of windows. Ex: Dell Inspiron 3543, windows 10
