internal hard disk is not found

[Rezan]

hi,

one of my friends faced a problem in his laptop, he brought it to me to check it up , when i started windows (once i powered on) it was saying no bootable hard drive found , internal hard nato found ,try to reseat the hard again, i ran diagnosis and tested laptop it was saying internal hard disk not detected.
i switched off laptop and removed battery, then i removed hard disk , i reseated again ,but not fixed still same trouble.

any idea?

Hard Drive sounds like its bad. Do you have a spare hard drive that you can place into the laptop to see if it detects a healthy hard drive?
