I was trying to upgrade my gf's laptop (inspiron 7537) to Windows 10 yesterday and it hung up on installation. I left it overnight and was still hung up so I powered it down and restarted it. Now it shows the Dell screen and loads to a black screen. I have tried pressing the "CTRL" button then entering in the password and waited but no luck. I restart and I press the "Delete" button to display the bios options (F2/F12) but when I press either button it just ignores it and goes to the Dell screen then to the black screen again. I want to go back to Windows 8 (on a USB already) and after what I read this morning I need to update the Bios before I do the Windows 10 upgrade but it will not let me do anything.
Any help or suggestions would be great!
Thanks!
