my dell inspiron3135 series 3000 cant boot it replays no boot device found...so is my hdd dead and how can i repair it
Check to see if the hard drive shows up in the boot list (F2 at powerup). If it doesn't, it's toast.
If it does show up, run a full diagnostic (F12 at powerup) on the drive -- if it fails it'll need to be replaced. If the system is under warranty, call Dell with the error; if not, any 2.5" 7 mm drive will work as a replacement.
i diagnoised it and the hard drive is not applicable.
.so i must have to replace the hdd
