Hi there, I'm using Build 7000 of the Windows 7 beta... I had Vista as my main operating system... my HDD was already split into 2 partitions (plus I had a separate physical drive, for 3 drives total)... I installed Windows 7 on the other partition of my main drive (dual boot). Everything boots and seems to run fine, however Windows 7 will not see the other partition in "my computer"... It will see the separate physical drive, so I have a total of 2 drives listed... but it doesn't see the other. When I go into my computers properties it does see the hardware, but under "volumes" it doesn't show a drive letter, only the drives name. I'm hoping this isn't the actual proper behavior, possibly due to the fact that the drive has another operating system on it, or for some other reason like that. Any help would be greatly appreciated. Andy. Edit: Sorry, figured it out... just had to set it up in Disk Manager. Thanks.
