I don't know anything about this topic. My computer was working fine one day and then the next I am having this problem. The problem is as follows: When I start my computer I get the black laoding screen which displays the following: Searching for Boot record from CDRom - Not Found Searching for Boot record from SCSI - Not Found Searching for Boot record from Floppy - Not Found Boot Failure Reboot and Select Proper Boot Device or Insert Boot Media in Selected Boot Drive Press any key when ready I don't know how to fix this problem I have read previous threads but it's all foreign to me. Can someone please tell me in simple terms. I am running Windows XP Home Edition, have Service Pack 2. I have 2 discs for XP 1:Home Edition 2:Office XP Professional and don't know which one I would use. I can bypass this problem by pressing the left button on the tower but then I have problems such as the Start Menu will not pop up unless I go into My Computer/Local Disc(C and then run a search for the Start Menu then the computer acts likes nothings wrong but I don't like doing it this way as I'm feel I could stuff up my whole system. Sorry this thread is so long. If someone could help and explain it in simple computer language it would be greatly appreciated and I will Thankyou ahead of time.
