Installed Windows 7 on a newly assembled PC (yesterday). Runs fine. trying to install Ubuntu 12.10 64bit from DVD but installer does not give me an option to install "alongside" Windows 7. I only get the wipe everything or go fiddle with the partition options. "no operating system found"
Intel mobo DH77DF with an mSATA SSD of 256GB, primary partition with windows 7 is some 60GB, with the rest unallocated.
Installer running off a USB DVD drive.
Looking at the drive from the installer's partition mapper the Windows partitions can be seen, but no operating system is found.
How do I get around this?
I've installed various linux distros over the years and never seen this before.
