    Installed Win 10, still boots in Win 8.1


    I attempted to install Win 10 on my HP 7000 laptop with 6GB memory, and gobs of disk space. At first, I got the C1900107 error. After an internet search, I renamed (effectively removing) the .-BT directory. I started the download again. That went fine. Then it did the "configuring files," which seemed to take forever. I walked away for a moment and when I returned, the window was displaying a message to restart the computer. No error messages were displayed. I restarted the computer, in which it installed several updates. But when it came back up, it was still under Win 8.1. I would appreciate any help anyone can offer as to how to get the computer to come up in Win 10 after an apparently successful install.

    :)

    Win 10 upgrade on a Win 7 and Win 8.1 multi boot system

    I have a system that multi boots into win 7 or win 8.1. Why ? Well win 7 is 32 bit and win 8.1 is 64 bit and I was going to slowly set up the 8.1 system to mirror the programs on the 32 bit Win 7 install as there is no automatic 32 to 64 bit migration path.
    Both have genuine Win 7 and Win 8.1 licences. I delayed the 8.1 upgrade as Win 10 was coming.

    Can I upgrade the Win 8.1 install to win 10 and keep the multi boot options as Win 7 and Win 10 or will the win 10 upgrade kill the current multi boot configuration.

    Any advice appreciated

    Two corrupt versions of win 10

    Hi! I installed win 10 on a new ssd, but I kept my old system (win 8.1) on my old ssd. The computer booted fine, but right into win 10, with no alternative to start the old system. I could still access it by using bios to select my
    old ssd to boot win 8.1.

    I got the tip to use easyBCD to set up a dual boot. I did that. Everything worked fine. I started using win 10 a bit to get used to it. Only installed drivers, office, chrome and antivirus. I made it go automatically into win 8.1 if
    I did nothing in 5 seconds, and that worked fine multiple times too.

    Today I started up the computer and nothing booted. Win 10 gets an "inaccessible boot device" and win 8.1 won't start at all even if I disconnect the new ssd.

    I am at a loss, and I havn't even tried more than restarting with no devices attatched but a keybord and a mouse. How do I approach this?

    Installed Win 10, still boots in Win 8.1

    Hi,

    It looks as if Win 10 install wasn't successful and rolled back to Win 8.1 The fact that you were asked to restart the machine is a pointer to that.

    No idea what caused it, short of digging in the setup logs it's anyone's guess.

    Cheers, *Wink
