Boot failure during startup Alienware 17R4. It says boot failure on device. Windows 10. Just started. I reset the
Set Boot Mode to UEFI (if Windows 10 was installed in UEFI mode). Ensure the SSD or HDD with Windows is set as the first boot device. Save changes and exit the BIOS. If the laptop still shows “boot failure,” create a Windows 10 installation USB using Microsoft’s Media Creation Tool.

Boot failure on device
How old is your Aurora R13? "boot failure on device" means that BIOS was not able to find an operating system to load into. Your harddisk could have failed, and BIOS cannot access it, and therefore it didn't find any operating system to load. More on reddit.com

r/Alienware on Reddit: Alienware x17 R2 Boot failure
May 21, 2022 -

Hi,

I just got my Alienware x17 R2 laptop yesterday.

Today, when I turned it on for the first time, I got this error:

“ No bootable devices were found! Possible causes could be a corrupt OS image or a boot device is not enabled in BIOS setup.” and I only had this option to shut down the device. The next time I turned it on I got this error " Boot failure on device".

I have not changed any boot mode configuration. The UEFI option is on "Windows boot manager" by default.

I think they have not installed any windows on this Laptop in factory.

I would be thankful if anyone here can guide me what is the problem and what should I do now?
