Yesterday I was using the laptop like normal and I shut it down like I do normally. Today I turned it on and when I start the laptop i get a error message that says:

PXE-E61: Media Test failure, check cable
PXE-MOF: Exiting PXE ROM.
Operating system not found.

Can anyone help me get it back?? Keep in mind, I dont have F keys

Ive read on the internet that it has to do something with the BIOS in the boot system or something like that. Please help if you can!!!!
