Hi ,

Have you tried to Start your system through Last Known Good Configuration Option ?

I actually tried updating windows vista to windows 7. The upgrade failed and the pc indicated it was restring to windows vista. however when I power up the pc, I get 'No Boot device Available' followed by
SATA 0: Installed
SATA 1: Installed
SATA 2: None
SATA 3: None

My hard drive is connected to SATA 0 and my CDROM is connected to SATA 1.

In the BIOS settings, I have the hard drive listed first, and the CDROM listed second for boot order.

Any assistance with this??

For non technical people who need a solution on how to fix the Blue Screen of Death, there is no simple answer to that.

The Windows operating system constantly refers to the registry to get information about all of the components such as hardware and software which are installed on the computer. The registry tells Windows what to do and how to access the various programs, files, and processes.

However, the registry can contain bad information which sends Windows off doing useless tasks or running unneeded routines. Sometimes errors occur including the blue screen of death. Other times the system slows down. Because of the sheer number of factors that can affect the registry, there’s no one size fits all approach. You can’t just go into the registry and remove the bad information because it’s nearly impossible to decipher which information is good and which information is bad.
