Hi !!!

I bought inspiron 15(3593) recently and had some issues regarding booting system.

and then I tried to reset my laptop to factory resetting with USB booting

but it didn't work and then I wiped virtual drive

and I tried to  to reset my laptop to factory resetting with USB.

But factory reset icon isn't activated

after restarting laptop, push F8, and try to reinstall system but network adapter was disabled 

and there was message that no bootable device were found possible causes could be corrupt OS image or a boot device is not enabled in bios setup"

 

How can  I reset my laptop to factory setting?
