Initial Partitioning

After all the trouble that I went to remove the old partitions on the HD in my secondary rig, I forgot to disconnect a second HD installed, and after going through a number of other repairs just before starting the installation, I wasn't thinking clearly and deleted the partitions that I had made with the HD installed on my primary rig.

Attempting to recreat the partitions with the installation procedure got things even more messed up because I didn't find any facility for actuallyt creating a partition of the size that I wanted, only a format function, which I assumed would format the entire drive, or as I did, click Next, hoping to find something more in the next screen, but it then just started the installation itself, and took the entire drive, except a 100MB partition that it also created for the system reserved functions.

Not being in the mood to once again remove the harddrive back to my primary rig for prep, I let it continue the installation, because it would not permit me to delete the partitions that it had made. I'm hoping that I can resize the main partition after the install completes, but if like when I installed the x32 bit version in this manner, it scattered files across the partition in a fashion that would make it difficult to do so.

On my primary rig, I have the entire OS installed on one neat 100GB partition, and that is what I want here also. I'm trying to decide whether to nuke the HD again, or finish the installation and attempt to customize it afterward. Which would be better?

I think that there must have been a difference in the download that I used to install on the primary rig, because I had none of these problems before. I will finish the install, but it just doesn't feel right.
