I think Rammit was on the right track...did you check the boot order? Even better, when your 15z reboots after stage 1 of the Windows 7 install, press (actually repeatedly) the F12 key to direct you to the boot menu, then make sure you choose the SSD to boot from.

You can also just remove the USB stick during the first reboot, too, as the Windows 7 install doesn't need it (you can plug it back in once the SSD starts booting, if you feel like it).

Since I don't have two "HDDs" in my 15z, I can't say, for sure, how the system treats the HDD connected to the DVD connector, make sure in the boot options in the BIOS that the hard drive sequence is correct. You want your SSD to be the first hard drive in the HDD sequence.

Set your boot sequence however you want, and use F12 to manually choose the boot device during Windows 7 install.

Good luck!
