Installing Ubuntu on a Pre-Installed UEFI Supported Windows 8 system
I have a windows 8 dev preview install, with plenty of unused (unpartitioned) space on the hdd. However, the ubuntu installer (from usb) doesn't recognise windows 8 - it says:
This computer currently has no detected operating systems. What would you like to do?
With the option to either erase the disk, or do "Something else". If I choose the second option and select the "free space" area and "Install Now" I get:
No root file system is defined.
Please correct this from the partitioning menu.
So: is there anything good I can do here to run on-the-metal side-by-side? The alternative is dropping one (probably Ubuntu, since windows 8 is already there) into a VM.
