Okay, let me be more clear: where did you get the netbook from?
Something isn't lining up here...your Disk Space Reporter report says your C: drive has about 17GB used...but Disk Management says you've used almost all 116GB...I don't know why there is a discrepancy. That is very strange...
Okay, if you want to size down D, use Easeus
. Shrink D from the left to the right, then extend C from the left to the right (into the space formerly occupied by D). Be sure to click Apply
in the lower left pane of the window.
By the way, you can install Windows 7 on any computer without having to use the DVD directly. If it's a regular, "retail copy" of Windows 7 (OEM copies don't typically work), you can copy the setup files as-is from the DVD to an external hard drive, mark the partition as active, then boot off it and install Windows 7. This is how I do all my clean installs of Windows 7, as it is much faster than using the DVD (hard drive spins faster than optical drive). Makes it easier to install on the netbook, too, for obvious reasons (no optical drive).
