This Linux Swap Space Mini-HOWTO describes how to share swap space between Windows and Linux. Do these instructions still apply to Ubuntu in 2011? How should I modify the steps for Ubuntu? Is there a better approach to sharing swap space?

Based on the HOWTO, it seems best to create a dedicated NTFS swap partition:

Dedicated so the swap file will be contiguous and remain unfragmented.
NTFS so both Windows and Ubuntu can read/write to it. (Or is FAT32 better for this purpose?)

Then, configure Ubuntu to prepare the swap space for use by Linux on start up; by Windows on shut down.

I want to dual boot Ubuntu and Windows 7 on my X301 laptop. However, my laptop only has a 64 GB SDD, so I would like to conserve as much disk space as possible.

update: There is an alternate method using a special driver for Windows that let you use a Linux swap partition for temporary storage like a RAM-disk, but it doesn't seem to be as good...

How do I know if I am running Wubi or a proper dual-boot?

I tried to setup a "proper" Windows/Ubuntu dual-boot system, by installing Ubuntu from a USB key. However, I simply could not get the laptop to boot off the USB despite the fact that I made the appropriate changes to the boot device order in the BIOS. So I then turned to Wubi, and (to cut a long… >>> More
