|A computer needs to have an OS. Since your hard drive died the bios has been left in a situation where it tried to boot to the hard drive but the only choice left was PXE. Since you don't have a pxe server you can't boot to a network OS. |
If you want you can go to netboot.me or BKO.org and get a cd or floppy to boot over the internet.
Why did it take me over a year to phone in a problem to ATT?
