This series of error messages- Boot Device Not Found, Hard Drive not Detected, No Boot Device Found, No Bootable Device,, No Boot Partition Found, Hard Disk Drive Failure, Data error Reading Drive, Blank screen with flashing Cursor, Seek error – Sector not found, Missing Operating System, Operating System Not Found, Primary Hard Disk Failure, Error Loading Operating System, Drive not Ready- all these messages are really saying the same thing. The computer can’t find your operating system so it can’t boot into Windows.
The easiest thing to check is whether the hard drive, or the cable running to the hard drive may have come loose from the motherboard. Connecting the drive or cable snugly to the motherboard will quickly resolve the problem.
Virus or malware infections can also damage or remove the Windows boot files, which would give you this message. Sometimes a Windows Update doesn’t install correctly or isn’t finished installing when you restart your computer, and that can prevent Windows from starting too.
Many times, the error results from some type of problem with the hard drive itself. You can read my post about some of those problems here.
