    Windows disappeared after installing ubuntu


    Hello! I hope I'm in the right place.

    TL;DR - I have more than one hard drive and everything was just working. Added a new SSD and got windows set up on it. installed ubuntu on the old 250 gb SSD. Now I cannot access windows, it wont boot and does not show up in the MSI motherboard BIOS or during bootup. Also, the BIOS are less than helpful. It's like the windows installation just fell off the planet.

    I I just got a new SSD and everything is installed (windows)but then I installed ubuntu on my previous main drive and now there's no options or way to get into windows 10. I have an MSI motherboard and it's boot options are not great IMHO. - I Already had this working but after the SSD upgrade it seems to have gotten more complicated. I have 4 drives hooked up to it right now, I had 3. a 250 gig SSD (ubuntu installation), a terabyte SSD (for main windows 10) a small SSD that is not really doing much., and a 2 terabyte backup drive.

    The only thing I can think of doing at this point is unplugging everything but the terabyte SSD drive and then add in the others.

    Thanks for any help or to tell me where I could get some help.

    Welcome to the forum. Are you using grub as the boot loader in which case you will need to add windows. You first need to disable other drives except windows so by know it still works. Its possible if you installed windows with other drives in that it put boot files on another drive​

    Disable? So unplug the other drives?

    I think that when you installed grub became your boot manager and it will need to be told about the windows install.
    (I guess what Samuria was trying to suggest was to disable other drives so that you can check that the windows install is still OK. With the other drives disabled bios will have only the windows install to boot from.)

    Perhaps this will help you get windows running:

    Ok so i unplugged my other drives and yes something is wrong with the new drive installation. It shows up in bios/if I try to install windows and go to partition manager. So it works but I cannot get it to boot to the installation.

    Remove Linux and connect other drives does it boot then if it does post screen shot from disk manager showing all the details boot files maybe on another drive

    If Ubuntu was working, reinstall the drives in their original configuration, start the computer and when the grub menu appears, press the down-arrow key. This should stop the grub countdown and allow you to examine the grub menu. Look for "Windows 10" and if you see it, use the up and down arrow keys to highlight it and press "Enter".
