That's OK but if you do that, pick which to use for your discussion.
TO GET YOUR FILES OUT I suggest you put the drive from that PC in some USB case or cable like this example.

The answers to your questions may be.
1. Sounds like a dead hard drive. If you pull the HDD and put it on that case or cable, you will know more.
2. Almost never. However, HP may have Vista for download.
http://h10025.www1.hp.com/ewfrf/wc/product?cc=us&lc=en&dlc=en&product=3832291 noted this shipped with Vista and as we read http://forums.cnet.com/7726-13974_102-5325452.html?tag=posts;msg5325452 you should ask HP if you can do the same.
3. No. For today you replace the 20 buck DVDRW drive before you use the recovery media that will wipe out whatever is on the current HDD and restore it to factory condition.

PS. Just a question. If your files are important, why are there no copies?
