    Strange Dual-Boot Menu Problem


    I have a dual-boot problem. My desktop PC has two harddrives, Drive 0 and Drive 1. Drive 0 (my primary boot drive) has a single partition containing Windows 10 on Drive C:. Drive 1 has two partitions: a 100MB System Reserved partition containing the MBR, etc., and a large partition containing Windows 7 on Drive D:.

    The Windows 10 OS was upgraded from Windows 7. The Windows 7OS on D: is a separate copy (not the copy used for the upgrade to Windows 10).

    Both operating systems work fine, but the dual-boot menu that gives access to them is behaving very strangely. After a hard boot, the computer invariably goes straight into Windows 10. When I do a warm boot, however, the dual-boot menu is displayed, and I can choose either OS.

    I have tried extending the display interval in Startup &Recovery, but it made no difference.

    The odd thing is that, to begin with, the dual-boot menu was appearing correctly after every boot. The problem may have started after a Windows 10 update, but I am not sure.

    Any suggestions for fixing the dual-boot menu problem?

    My guess is that the boot directly to Windows 10 only occurs when you do a shutdown from Windows 10 and not from Windows 7.

    Windows 10 uses a fast startup function that really is hibernation like. It allows a quicker startup and bypasses the boot menu.
    When you do a restart in Windows 10, the system does not use the fast startup function and really does a hard startup and thus goes to the boot menu.

    This is all normal. If you always want the boot menu, then disable fast startup in Windows 10.
