I'm trying to dual boot desktop Ubuntu for the first time, and hopelessly flummoxed by the partitioning process. I've got a Lenovo notebook (Windows 7) with a 500GB HDD + 28GB SSD, and my goal is to create a single small (~24GB) Ubuntu partition on the HDD for both the OS and filesystem (i.e. I don't need to share files between Ubuntu and Windows).
This is what I see in Windows Disk Management, after shrinking the C: partition to leave that 23.44 GB of unallocated space:
There are only 3 primary partitions (SYSTEM_DRV, C:, and D:), so there should be room for another. I assume the OEM partition is a system restore partition.
I'm totally lost about what to do on the Ubuntu side. When I try to install it from a bootable USB stick, I don't see any devices in the list:
I've tried 12.10, 12.04, 32-bit, 64-bit, and multiple USB sticks, but nothing ever shows up, and the buttons along the bottom are inactive. I'm supposed to choose a device from that field, right?
What am I missing?
