It sounds as if your computer is trying to find a boot image over the network. PXE is the preboot execution environment

That usually means your BIOS can't read the hard disk - bad BIOS, CMOS battery died, ...

What did you change ?.
Does a liveCD boot ok ?.

A system will try to boot one option at a time from different forms:
Hard disk
Removable media as USB, etc

You can setup in the BIOS what it would try first, like: hard disk, to speed up the search for a bootable mean. By default your BIOS might want to try first the Network. It will try one option after another until there's no more options. If none is found, it will display
Operating system not found
If you have never seen that output, it could be a sign of a few things.
The BIOS setting got reset to default, however that would not prevent to boot eventually from the hard drive.
The hard drive has failed and the system does not see any, or it does not see it as bootable device.

That's normal output saying it is using the network card RELTEK to try to boot from Network.

Welcome to LinuxQuestions!

What make and model is your computer? I agree with the others, your computer is trying to boot an image over the network and obviously not finding one available.

You need to check out the boot order set up in your BIOS as mentioned by Aia above. The boot list would normally be set to something like:


Floppy (if you've a really old system! What do you mean, "What's a floppy?")
Hard drive (With no removable media fitted, this is what you should normally boot from.)
Tape (to restore stand alone backups if required)
Network (PXE) (If all else fails, is there an image on the network?)


Note that if your boot order were set up as above and, without any removable media installed, should your hard disk have failed, the BIOS would attempt a PXE boot.

I hope this clarifies rather than clouds the issue.

Play Bonny!

Your machine is trying to boot from the network first & failing.
Exiting PXE ROM
Then it has tried to boot from a disk on your machine, but failed to find an operating system.

Looks like you are either missing a boot loader, or the operating system itself.
