This is a a follow up question from here

I recently got a new computer and I have been trying to get a dual boot Windows/Ubuntu to work, so I got ubuntu on a usb key( using Rufus as recommended in the Ubuntu page) and after solving the problem on the previous question, I manage to get into the try version of Ubuntu, but another problem appeared when I turned off ubuntu ( from the try version, It was a bit late so I decided to install it later the next day). It took a long while ( about 3 min) for the desktop to disappear (in the mean time it was frozen). When if finally disappeared I found this message(which again contains the "Couldn't get size error): enter image description here and it continues: enter image description here This makes me worried about installing it from this key. Should I just try to install it anyways(hopping that is only a problem booting from the USB key)? or this problem could persists in the installed version?

UPDATE: When trying to install it, it doesn't recognize the windows installation and If I choose "do something else" it only recognize my HDD, it doesn't see the SSD where windows is located. It is possible to install ubuntu in the SSD? If not, if I install it on a partition of the HDD, would this allow me to dual boot?

  • I suggest that you install Ubuntu anyway. I think that it is a problem specifically when booting from the USB drive. In the installed system you may need the boot option nomodeset and later, when running the installed system, install a proprietary nvidia driver to make the graphics card perform well. – sudodus Sep 24 '19 at 7:01
  • @sudodus Thanks, I just tried that, and It seem that Ubuntu doesn't see one of my drives, I wonder if this is related to the original "couldn't get size" problem (I updated the question with some details). – themaker Sep 24 '19 at 7:26
  • Often when Ubuntu doesn't see the Windows partition, the problem is that Windows is hibernated or semi-hibernated. Semi-hibernation is also called Fast Startup and can be turned off in Windows. But it should also work to boot into Windows and reboot (not shut down). Beware, installing operating systems is risky, so backup everything that you cannot afford to lose before you start on this adventure. – sudodus Sep 24 '19 at 7:31
  • Which version of Ubuntu are you running on your USB pendrive? 18.04.3 or 19.10? If 19.10, please consider, that it is not yet released, and there may be serious bugs, that will be squashed before it will be released. – sudodus Sep 24 '19 at 7:47
  • @sudodus All the times I tried to install ubuntu was from rebooting from windows. The version that I have tried is 18.04.3 at the moment. Thanks for the advice about installing OSs. – themaker Sep 24 '19 at 9:48
