[Inspiron 7568] Boot from USB Drive Triggers SupportAssist Diagnostic Page
Hi,
I've created a bootable USB Drive which contains Windows 10 installation using Rufus. When I try to boot from the drive, the laptop shows me SupportAssist diagnostic screen and doing some tests. When it shows up, I press ESC to cancel the test, then the laptop turns off. But, when I try to boot to Windows on the internal hard disk, it works fine without any problem.
Please help me identify the problem.
Thanks

I've found the solution.
I have to turn off Secure Boot in the BIOS, because it will refuse to boot from my USB Drive when it's on
