On a N586, I have just installed 12.10 alongside Windows 7 and kept the OKR working. I did not find an exact how-to anywhere on line, so did it my way. It worked (so far !). You need to be comfortable repartitioning.
Problem is that Lenonv uses 4 primary partitions for their Windows 7 install. Solution is to turn the main Windows_OS partition C:
into a logical one - this works because Windows actually boots from the 200MB SYSTEM partition which is still primary. Then you can shrink the C:
drive and run the Ubuntu install which will use the remaining space. I contemplated making the D:
drive logical as well, but was not sure if OKR would get upset. Seems simple but it took ages to make it happen.
I have Windows 7, Ubuntu and OKR all working.
Some specifics:
Make rescue disk and full recovery disk set first! Most folks recommend two copies, just in case.
I used a bootable partitioning tool (GParted) to re-characterize the Windows_OS space
Then back into Windows to use the Disk Management tool to shrink the windows partition (hint: defragment it first to shift some files down)
Then run Ubuntu install. You could manually partition, but I tried the "install alongside...." option and it worked a dream
As for hardware compatibility, the only thing I'm struggling with is the internal microphone. Everything else seems to work out of the box.
Good luck!
