    Dual boot win 7&10, Win 10 boot option is not showing up anymore


    I've had both windows in all my computers since the beginning of w10. On this computer win7 was on B drive win10 was on C drive. It is one drive partioned in half Have all my docs, mail, pics, music on external drive. I was using them on both os. Well all of a sudden the page where you chose os doesn't come up anymore and it boots to win7. Windows 10 is still in C Drive, but no way to start it Do I have to start over again or just reload win10? I want to f disk c drive and clean it up, reparation the drive again and start over. Am I going to have a problem loading win 10 or will Microsoft remember my computer?
    Thanks in advance.

It was there - options for booting into Win7 or Technical Preview. The 'time to display....' is set at 30 seconds but only Win7 is showing. Any thoughts appreciated - regards.
