Is Windows even installing?

Absolutely not, and you may have tried to install over OSX, in which case your Mac is now empty. To test, remove the dvd from the drive, restart and hold the option key as soon as you hear the chime. When the boot manager loads tell me what choices you get.

Did you use Boot Camp to prepare this install or did you just put the Windows disc in the drive?

Can you boot to OSX?

Check in disk utility to see whether or not a Boot Camp partition exists.

$300 is a lot, but what version did you buy (not important really, all versions of W7 work).

Download and read this:http://manuals.info.apple.com/en/boot_camp_install-setup.pdf

Backup your machine (Clone or TM)

Use Boot Camp Assistant to remove the partition and start again.

First you try and now go through and re-read.

Retail disc or ISO and the DVD as well as the SuperDrive and other factors,, and you will want to have 50GB set aside.

The partition part takes two minutes, the download of Lion (OS version?) takes 30 minutes or 3-9 hrs depending. Those just leave on FAT flash memory card.

That's fine, but you were overcharged, read the following post before you start again, and backup.

Feels like we go backward two steps for every attempt to put one foot in front...
