multiple OS. RRS feed

  • Question

  • Windows 10 will not do duel boot.  When Windows 10 put on two hard drives I can only access with Alt 12 and pick the drive you want to boot.  When doing start up repair it will not correct the problem most likely because it only reads OS on one of the two drives.  I have done over a hundred multiple boot setups so I'm thinking this is problem needing to be fixed by Microsoft. Anyone having done a duel boot on Windows 10 setting up Windows 10 on both drives with a boot menu allowing you to pick either one please tell me how you did it.

  • Hi,

    What does your meanning by "When Windows 10 put on two hard drives I can only access with Alt 12 and pick the drive you want to boot. "?

    Is both of these two system Windows 10? Please use bcdedit /enum command to list current PC boot entry. Then check if there is any error with it.
