    In modern windows 10 installations, windows 10 partition (usually drive c:) is not the most right partition physically on the disk, so shrinking it does not solve the problem of getting free space on the right side of the disk to allow installation of Ubuntu, because you only get a gap in the middle of the disk.

    However the latest point release of Ubuntu (I use xubuntu) does seem to shrink and install alongside an existing windows 10 installation, so I would suggest to try a direct and simple installation of Ubuntu and choosing the dual-boot option.

    Great tutorial for dual boot, but do use swap memory! I kept using this tutorial and my Ubuntu kept crashing a few times per month.

    Hi Richard Blake,

    I search so much on google and tried different ways but till the moment I am not able to reach the installed Ubuntu version

    Thanks in advance

    The installation of Ubuntu 18 on an hp m/c with windows 10 installed ran as described in the tutorial. It was a bit difficult to force a boot of the Ubuntu DVD by intercepting the early stages with .

    The grub-install ran without error.

    There is no grub screen on powering up. I have not found a way to get into it. The windows booting process takes precedence. How can this be prevented?

    I have tried various combinations of boot set up. So far I have not found a combination that works.

    It says “Excecuting ‘grub-install /dev/sda‘ failed. This is a fatal error.”

    Hi, following these instructions I seem to have hit the “4 partition” limit in windows.

    I wondered if this aspect might be reviewed and perhaps included in this article if appropriate?

    Its a scary time doing this stuff so it does help newbies if “how to’s” cover as many of the points as possible.

    One symptom for me was that “free space” suddenly became labelled “unusable” at the stage of “something else” partitioning.

    I loved this tutorial! Very well explained, it worked fine on my Xiaomi Mi Notebook Air 12

    There is no need to leave the usb every time you boot ubuntu, therefore, you can use it for other things, but make sure you format it into NTFS, or you wont be able to transfer a lot of data to it.

  10. Madeleine says:

    Do I need to leave the USB in after I have installed Ubuntu to use it (Ubuntu) or can I use the USB for other things after?
