My First Vista BSOD
If you are installing vista after installing Daemon tools (in my case, I was upgrading the factory home edition to ultimate from MSDN ISO) and you start getting a blue screen after crcdisk.sys loads, the problem is most likely a file installed by Daemon tools. To solve the problem, launch the recovery console at boot menu, open a command prompt, and delete <WINDOWS>\System32\Drivers\sptd.sys and restart and the install should continue without bluescreening.
To anyone from MS that reads this post, please fix this in those installation updates that get downloaded to save everyone who doesn't read this post lots of blood, sweat, and tears.
