Installing 13.04 on an EFI partition - Share with Windows 8?
- by mengelkoch
Information I've found here suggests that for my system, I need to install 13.04 into an EFI-type partition, since it needs to boot as UEFI.  I also understand it is advisable to have only ONE EFI partition on the disk; I've read here that it is OK for Ubuntu and Windows to share the same partition (please confirm).  When I try to install into the existing EFI drive, I get the message "No root file system is defined.  Please correct from partitioning menu."  Do I change the EFI boot partition to another type?  Doesn't that defeat the purpose?  If I change it to Ext4 Journaling File System, I am given the opportunity to define the '/' Mount point.  I haven't proceeded beyond this point for fear I am going to destroy Windows 8 by altering this partition.  
BTW, I created three partitions in Windows before installing, per the helpful response to my previous question.  But if I try to install into the partition I created for Ubuntu, I get the "No root file system..." error again.
