My USB keyboard does not work during BIOS setup, so I can't change my primary boot device.

Is there a way to set the primary boot device from Windows?

Is there any other way to boot from CD?

I don't have a PS2 keyboard handy.

P.S.: After I got into BIOS, I enabled the Legacy USB Support, and now my USB keyboard works just fine.

Short: No.

Long: Windows can't control the BIOS. It's a very important concept of security to not allow the OS to change the BIOS. This is why boot-sector viruses were able to propagate.

Lesson Learned: If you know what PS/2 is, keep a PS/2 mouse and keyboard (or adapter) handy at all times.
