Help with windows 7 dual boot? -

okay i have just installed the windows 7 beta in drive d, and things are fine, the only problem is that, when i open windows 7 My Computer and check to only have one hard drive.....WHAT happen to the other one! I have partitioned it you know....so then when i go to windows xp, i can see the two hard drives again. C and D, d is where i installed my 7...do you know what should i do so that when im in windows 7 i can access the other disk drive, i want the program files cause its in the other drive??? thanks

Right click on My Computer and go to Manage...then click on Disk Management...you should see your partition somewhere there on your right with a asterix...right click on that and click on Import or Mount (can t remember) and that should bring your drive D into Windows 7.
