MEthod 1

Boot Sequence in F2 which is set to UEFI. I dont see Boot options (IPV4, IPV6). Attached are the screenshot of F2 and F12. I restored the settings to default and that enabled the secure boot. And now I get this error "OS Loader has no signature. Incompatible with SecureBoot. All bootable devices failed Secured Boot verification". Screenshot attached as well.

MEthoad 2: Dell Inspiron 13 No bootable device found.   

Also run diagnostic to check the hard drive on the system by following the steps below:

1. Power off the system. Remove all peripherals except AC adapter

2. Power on system, quickly start tapping the F12 continuously until you see Preparing one time boot menu in the top right corner of the screen. In the boot menu, stroll down to Diagnostic and then click on it.  After quick tests, click on Hard drive, and select Thorough Test Mode. Report back any error code.
