When I turn on my PC, I get an error message saying "Invalid Partition Table"

Cause - No operating system is installed on the machine

If the PC ordered from Cybernet was not ordered with an operating system pre-installed, some of the messages that may appear when turning on the machine are Invalid Partition Table, Improper Boot Device, or something similar. This happens when the PC looks to the hard drive for the operating system and does not find one installed. To install the Operating System, refer to one of our install guides.
