I checked your notebook on the HP website, and I don't see it listed in the Windows 7 supported computers list. Also, there aren't any
drivers available for Windows 7 x64 for your computer. Based on that, you might have problems getting Windows 7 to work after you get it installed. If you can't get things working properly, you can restore to Vista by following these directions:

I believe your problem is a complete lack of 64 bit SATA
drivers for your optical drive. Get yourself a 4GB (or larger) USB flash drive and install Windows 7 from that. Follow the instructions here on how to do it:
