Those who have upgraded to Windows 7 will have noticed that the boot process has been improved compared to the past, especially if you use the latest hardware and in particular an SSD. In this respect, Microsoft states that a computer with Windows 8 with SSD can boot in under seven seconds, a significant milestone for the company but is now facing the downside. It seems that the boot is so rapid as not to allow the user to intervene to stop the procedure and enter the boot menu with the classic F8 key.
Currently, the user has a "window" of 200 ms, which is insufficient for practical use in case of problems at startup or simply to another installation. Chris Clark, director of Experience team at Microsoft, so he announced that the company is trying to "solve" the user by providing (final version) option adequate and above all simple, with the possibility of an automatic mode when the process is made impossible by the failure of the S.O.
Clark's post is quite detailed and can be found at thislink .
