[seretide]

after some much needed help with the following please, my laptop is a presario c700 when i turn it on it says the error message "no bootable device -- insert boot disk and press any key", have checked boot order, and only option is cd/dvd drive, no hard disk option, in bios it only gives cd/dvd boot option, have performed hdd test and memory test, which come back fine, seems to be no bootable software on the laptop, looks like i have no windows or software or drivers what so ever anymore, i assumed i could restore the laptop with out discs as it says on leaflet supplied with it, but cant find how to, i dont think this function is present anymore either, i dont have a restore disc as it didnt come with one, was running vista
any help much appreciated
thanks
