Windows 7 and Karmic Koala

I upgraded my Toshiba laptop to 4GBytes of memory and a 500MByte drive. Then I installed Windows 7 - it detected the wireless network but not the graphics. I couldn't find a Windows 7 driver for 64 but the Vista one worked fine.

Ubuntu Karmic Koala running from the live CD worked fine but now it's installed it first had issues creating a FAT32 partition (kept failing) then the wireless doesn't work (worked on live CD).

Hmm...

Update: after rebooting Ubuntu, the wireless network worked fine. Also let me create a FAT32 drive, label it, format it and leave a file for Windows 7 to see. Windows 7 didn't offer me the option of using FAT32 to format...
