Windows 10 boots in around six seconds with a SSD drive and UEFI secure boot
I have a dual boot system I just built last week, 7 on one SSDI and 10 on another.
I was impressed with how fast it boots, but while 7 was stable when I overclocked, 10 wasn’t.
Would love to know your machine config.
Best I get with an I7 @3.9Ghz with a Samsung 850 Pro SSD is just a shade under 11 seconds.
