it all started like this. I cleaned the dust from the inside of my pc, have not done it in a while so it was covered in dust. I vacuumed it, closed the cover and turned it on. Then I get the message "disk boot failure. insert system disk and press enter". I checked the net, and all I could find was the tip to use the install cd to repair. I tried, but it would not recognize the hd. All cables are attached. At a complete loss. So I attach an old hd, install windows on it. I open the arbeitsplatz (sorry, my system is in german, its where your partitions (c,d,e) are, dont know the english term ). And behold, the partitions from my other hd are accessable. And now I get angry again..... I must restart the system, so I do. After restarting, I open arbeitsplatz again....and my old partitions are not there. Gone. I need that hd. I have many things there, including some nice videos of my ex-gf really want that. So please, if anyone knows if/what I can do, please help me.
