I am trying to install Linux Mint 18 Cinnamon alongside Windows 10 on a new Dell XPS 13 laptop. Following a tutorial, I shrunk the Windows partition, leaving about 97 GB of unallocated space (GPT partition style) on my hard drive, and I made a Linux Mint USB drive using Rufus. Booting from my 4 GB USB, I chose the option 'Start Linux Mint 18 Cinnamon 64-bit'. Next, I clicked the desktop icon 'Install Linux Mint', selected English as language and then got the following error message:
You need at least 9.9 GB disk space to install Linux Mint. This computer has only 4.0 GB.
The installer does not seem to see the internal 97 GB disk space, or is perhaps trying to install Linux Mint on the USB itself? I have seen some forum comments suggesting to change the SATA operation mode, currently this is set to 'RAID On', the other options are 'AHCI' and 'Disabled'. I'm afraid of messing up things, any idea what will help?
Update: Tried with an 8 GB USB stick, the message changed to 'This computer has only 8.0 GB.'
