Did I forget anything???

Problem: The computer came with an 80 GB drive. only 10 GB allocated to the OS and the rest was allocated to free space and some kind of repair utility.
Several years ago, I installed a 300GB Maxtor (seagate?) as a 2nd drive. I was very cautious not to install extra programs on the C or D drives - I exclusively installed all other programs on the larger 300 GB drive. All was well until a few weeks ago when I kept getting the dreaded 'running out of free space' warning. Then the computer shut down of its own accord several TIMES and I realized that I had to install a new main drive. I have another 250 GB Maxtor drive. I erased it with KillDisk, then tried using MaxBlast 4 to partition it. It seemed to work fine. I got to the part where it tells me to reboot and wait for the blue banner STATING that a DDO is installed, then I'm supposed to click "C" and insert the OS disk, and continue with the install. It all begins well enough, however, after the 2nd or 3rd shutdown in the process, I get the following #90 error: "EZ-Drive has been detected on Drive 0, but EZ-Drive is corrupt. Run the EZ-Drive setup to correct this problem. For EZ-Drive support contact your EZ-Drive provider." Huh?? Anyway, I click OK, then it appears to reboot, and then it says: Error Loading OS.

It's been a long time since I've done this, but I know for SURE I didn't have this problem the last time I went through this process. Can someone give me some guidance here?

I want to install the 250GB as my main drive and keep my 300GB as the 2nd Drive. But I can't seem to get where I want to go....

Thank you in ADVANCE for any help you can provide, but if at all possible, could you try to keep your answers in layman's terms because I'm not a computer wiz or anything....
