    ssd marked accidentally as active


    With mistake i accidentally marked one of the ssd's as active and now i can't use it for anything.
    it wont delete it wont format i have no options in disk management for it.

    when i press erase it says that "Windows can't erase the active system partition on this disk"

    says the same thing when i try to format from "my computer".

    i know that only the OS drive should be marked active and i want do to something about it. cause i need the ssd...

    Normally you use diskpart command to mark it "Inactive". However, you have to be sure it's not the partition Windows boot from. Show us the screen shot of Disk Management then we can help you.

    i just reinstalled Windows 10 since somehow after accidentally marking the other disk as active and then after a reboot of the computer made sure that boot\bcd didnt exist.

    using the "repair the computer" just restarted the computer.

    and it just deleted the OS. i checked in diskpart using the Windows 10 dvd to "repair my computer" and entering cmd. the only partition i have now is the one newly installed Windows 10. so i can't do anything from there.

    i managed to mark it inactive. but can't format it or delete it.

    do you think i might be able to use easybcd to fix this since the disk i'm trying to format has the system flag still on it so that it wont get formatted...
