I'm attempting to install Ubuntu 16.04 alongside Windows 10 on a Dell G315, but keep getting the error of not having enough space on my drive, despite allocating 161GBs for Ubuntu.
I've created a Ubuntu 16.04 USB using Rufus & the ubuntu 64 bit LTS image. On my Windows side, I then shrunk my C: partition using disk manager; I have 7 partitions (boot, C:, 161GBs of unallocated, winretools, image, dellsupport, and 16 MB of unallocated)
Based on advice online, in Windows, I went to control panel -> all control panel items -> power options -> choose what the power buttons do and disabled "turn on fast startup"
I then booted into the BIOS settings by pressing F12 as I was starting up, and disabled secure boot; I left secure boot mode in deployed. I checked that I wasn't in legacy startup mode, and then under boot options added a new option for my ubuntu usb.
I then hit apply changes and exit, and rebooted the computer into the ubuntu on the usb, but about halfway through the install I get a message that I only have 7.8 GB on my computer and ubuntu needs 8 and a bit. I booted into the linux trial, and ran gparted, only to see the 7.8G of the USB.
I would think that this is likely a problem with secure boot not allowing me to see the full harddrive, but I'm certain it's at least disabled on the BIOS and don't know where else it might be enabled.
Thanks for any help you may have.
