No luck with my suggestion about setting defaults in the BIOS
I would take the hard disk drive out and put it back in again, just in case there is a bad connection.
I don't expect you will have a Windows DVD, but that's what I would try and check if it could see the hard disk/Vista drive. If you get that far, then try the Startup Repair option.
When you take the HDD
out, write down it's make and model. It will probably be a Toshiba. Look up the laptop model and HDD
at Toshiba (or go to the HDD
manufacturer's website). Check Frequently Asked Questions (FAQs), knowledgebase information and look for HDD
testing utilities (you can search for "flashing cursor" or "blinking cursor").
I don't think I have had to go that far when I have come across that problem, just set the default values in the BIOS
