Acer Aspire One Startup Problem!

Dear all,

Am so frustrated with this! This is what I get when I turn on my netbook:

Intel UNDI, PXE-2.1 (build 082)
Copyright (c) 1997-2000 Intel Corporation

For Atheros PCIE Ethernet Controller v1.0.0.13(2008/10/15)

Check cable connection..!
PXE-M0F: Exiting Intel PXE ROM.
No bootable device — insert boot disk and press any key.

Anyway, I’ve tried fiddling around with the BIOS, but the problems doesn’t go away… I have to submit a number of MAJOR assignments & all my work is on the net book. So any help would be seriously appreciated folks!
