I have a Dell Inspiron laptop that came with Windows 10 Home installed. Unfortunately I had to reset Windows and long story short, there was a problem resetting Windows so I went into the Dell troubleshooting options and tried to factory reset using my internet but for some reason this wasn't available on my laptop which left me in limbo without a working PC. I then stupidly ended up completely wiping the Dell PC including the Bios. I've now managed to get a hold of Linux OS and installed that on my PC so I can use it, however, I want to reinstall windows. The only problem is if I've completely wiped my Bios, will that mean I've also completely wiped the Windows Home Key that came with the laptop? If this is the case, is there a way to recover the Windows Key? Or could I provide my laptops service number or serial number that Dell could use to find my Key in their database? Any suggestions would be greatly appreciated.
