Re: Aspire S7 392 bios changes

Try these steps......

1. Go in to UEFI/BIOS settings and create a supervisor password.

2. Tab over to Security Tab

3.  Go to "Erase all Secure Boot Settings" enable/yes

4. Save and exit your UEFI/BIOS

5.  After you save and exit, the computer will restart.

6.  Go in to UEFI/BIOS settings and then to Security tab.

7.  "Restore Secure boot to Factory default" enable/yes

8. Save and exit your UEFI/BIOS

9.  After you save and exit, your computer will restart.

10. Go in to UEFI/BIOS settings and load the default settings (F9) and then save/exit (F10).

11. Create new UEFI Windows 10 media with rufus and the Windows 10 ISO.

See link below to guide on how to create Windows 10 UEFI installation media with rufus and how to use diskpart clean and install windows 10.  Even though the instructions refer to Windows 8.1, they are the identical for Windows 10.

If none of that works, then I suspect you have a hardware problem.
