I followed the solution and it said my hard drive was there, so I restarted and my laptop ran fine. Yesterday, the same error occured. I checked the hard drive again and it said it was there. Again, I restarted and it has been fine. I also disabled "PXE Boot to LAN" as suggested on page 2.
I've had this computer for around 1 year, 9 months. How likely is this to happen again?
UPDATE: It happened again today, but this time when opening the BIOS it said no HDD detected. Unplugged and replugged the HDD and it works now. Will update again.
