I ave a Toshiba laptop, and when I tried turning it on this morning it wouldn't turn on. First there was just a black screen, so I removed all power sources, and held down the power button to reset everything, then I plugged the power back in, and I managed to get to the toshiba screen, but then it says that there is no medium, which is strange, because yesterday it worked, and I did not touch it since then. I have removed the hard drive, and tried again. nothing. I have also removed the ram and put it back, and still nothing. I am pretty sure my HDD should not have died. I have had this issue before, but I can't remember how I fixed it. When it did turn on I backed everything up so I won't lose much. How can I fix this problem?
