Dual Boot Windows/Ubuntu Mate


My computer was running Ubuntu Mate on a SSD drive beautifully. I also had a HDD as well for a storage. I wanted to learn how to install a dual boot, so I installed Windows7 on my SSD. When I tried to install Ubuntu, I couldn't find SSD. Now Windows7 doesn't even load up. In BIOS, port0=Ubuntu, port1=western digital 500 GB hard drive. I decided to install windows10 in my hard drive hoping I can find SSD, but it's no where to be found. Can someone help me with this please.

I'm not sure I understand what you did. Your first installed Ubuntu on your SSD then installed windows 7 to the same SSD and are now attempting to once again install Ubuntu where?, the SSD, the hard drive? I would expect windows to have overwritten everything on the SSD if that is where you installed it and use up the entire drive leaving no unallocated space on which to install Ubuntu. You might be able to do something if you select the Ubuntu manual install option which is called "Something Else". Or did you do that?

When yu use the Ubuntu install medium, are you able to get to a Desktop? If so, open a terminal and run this command: sudo fdisk -l(Lower Case Letter L in the command) and post that output here which shows basic drive/partition info.

Hi yancek, I first installed Ubuntu in SSD then installed windows7 to the same SSD and now I'm attempting to once again install Ubuntu to the same SSD. Yes, windows has already overwritten everything on the SSD. When trying to reinstall Ubuntu, I selected "Something Else" but I found that I only have 32MB left in SSD. Ubuntu wouldn't allow me to install because the drive is too small. I couldn't even get a desktop to use a terminal as you suggested. Do you think my SSD is dead? What else should I do? Thanks
