The BIOS is set to boot from a network, and it can't find one. So press f2 to go into the setup (as invited) and check the boot sequence. For a normal boot, it should be set to hard disk as first item, not the network.
If it is already set to boot from the hard disk, and you still get this message, something is seriously wrong with the hard disk. The things to try (in this sequence):
1. Back to factory conditions via the system recovery partition or your recovery CD/DVD (and most likely an external disk drive).
2. Hard disk diagnostics using the maker supplied diagnostics.
3. Hard disk diagnostics via a Linux Live CD/DVD.
4. A new hard disk.
5. A new netbook.
Upon startup before anything else happens (except asking me if I want to press f2 for setup) my aspire one netbook says:
For Atheros PCIE Ethernet Controller... v18.104.22.168(1/22/09)
check cable connection..!
PXE-E63:error while initializing the NIC
PXE-MOF:exiting intel PXE ROM
No bootable device-insert boot disk and press eny key
I then can't get anthing to happen except for it to repeat itself.
what should i do? This is a Windows 7 home edition with a 1.66ghz atom processor and 2 gigs of ram. If anything else is needed I am more than willing to answer.
