Is there a way to reduce the time spent in EFI?
It seems more than 15 seconds that the Mac (Macbook air 2011) stays with the screen grey before beginning to boot (or resume from hibernate) to Windows.
Booting into MacOS is faster and getting to the grey apple symbol is very fast.
This video shows it: https://www.youtube.com/watch?v=HITe9-VOrDI
I need to add that I currently run Windows 10, but did boot camp assistant with Win7 because no native support of boot camp for my hardware and no Win8 product key.
Within Win10 it shows me: BIOS Mode Legacy and SMBIOS Version 2.4
(please give me a hint if you think this subject is better placed on a Windows part of Stackexchange.)
