I am working on my dentsist's computer and the thing will no boot into windows. When it starts up it stays on a black screen with a blinking cursor and after a couple of minutes it says "Error Loading Operating System". See what happened somthing happened and his son tried to reformat (which is doesn't know how to do or even knows what it means) and plus he doesn't have an Xp disc. Ive tried backing up the data with Bart PE but when i go to file managment no window comes up. Did he erase his partition or somthing? Or is the hard drive cooked, becuase sometimes in the post test it says somthing like "data error, replace hard drive". Plus I tried the test in Bart PE and it failed. Anything i can do to try to find any data? Or should i just reformat and if that doesn't work pick up a new HD
