Windows 7 and Vista Dual Boot Question

[Throc]

I'm currently running a fresh install of Vista Home Premium 64-bit. I have a copy of Windows 7 Beta Ultimate 64-bit that I want to try and set up a dual boot with one hard drive. My primary drive is a 320GB drive. My question is, how much space should I partition for Windows 7. I know they recommend a minimum of 16GB but I thought more would be better. I'm currently using about 250GB on the drive with Vista. Will a 30GB partition be enough? This will be my first attempt at running two OS's on one machine so any info will be appreciated.

I'm currently using a bit over 8gb of 25gb on my Win7 x64 partition.

Have my normal slew of programs installed as well, including Office07. So if your just planning on trying it out, 30gb is plenty.

30gb is plenty.

This.

Good luck!
