What does this mean? I have a compaq presario that keeps showing this. I put another HDD in and it is saying the same thing. Does it mean the old HDD was buggered and I need to do something to the new one to sort out boot order or anything? or is this not a HDD issue. I have two broken compaq presarios here. One with no screen working and one saying no bootable disk drive. Help. I must be able to get one going? Thanks
