ok so today took my harddrive into a computer store for another diagnostic. he hooked my hd up to a test computer, i was the slave his was the master, i was able to pull up my hd and open it look at the folder. so he shuts the computer off and puts mine up on master...the hd drive loads up files and then takes us to system restore..i tell him to do it he tells me i will lose all files i said i don't care. he couldn't get the mouse to work and tabbed over to cancel. tells me to get an os and redo the hd
so here's my problem i either never had the number for my copy of os or lost it, can i call hp to get my number ?
