"Operating System not Found" after resetting Laptop

[seaneryx]

While I was resetting my Samsung Ativ 700t, it turned off and then rebooted but it came up with "Operating System not Found."
The only computer I have access to is a 2010 iMac. I tried making a Windows 7 USB through Boot Camp Assistant but it still came up with the same message. If anyone needs info hmu. -Sean

check in the bios to see if the hard drive is seen.
