I am trying to go from 32 bit Vista to 64 bit Windows 7.

The 32 bit Vista was installed by mistake. My system can handle a 64 bit OS. Now I have finally found the time to upgrade. But the 64 bit intallation DVD can't be read from my OS. Any Advice?

Do I need to boot from that DVD drive? Will that work?

What you can do is go into your bios and set the boot sequence to look for the DVD drive first. (It might also help if you disabled the other sequences.) Then just press F10 save and exit, and then the PC will reboot and look for the DVD to boot.
