I had the same start up problems that I had the other day. This time, I know how I got around it. Last time the computer just kinda fixed itself eventually. Today, after a lot of aimless attempts, when it was booting and before I got the error message I hit the escape key and got the menu for boot options. I picked boot from the hard drive (which it should boot from anyway and was already set to do), and I'm in.
Instead of virus and spyware programs, this time I ran checkdisk and defrag after getting the system up again. Again both came up clean. At least I've got a workaround now for when it tells me it had a media failure and won't boot.
If anyone knows about the error messages below, I'd appreciate advice. Since this is the second time it's happened, I'm starting to worry that it may be a reoccurring problem that I'm going to have to address it beyond the workaround of bringing up the boot option menu and booting from there.
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM.
In other news, Fawn's a good dog. While the neighbor and I don't have a formal schedule for when our dogs go out, we have agreed not to let our dogs out at the same time. We try and check if the other's dog is out and wait till it goes in before letting ours out.
I think Fawn's figured this out too. This morning I forgot to check and let Fawn out with the neighbor's dog out. Fawn saw the other dog (right as it started yapping -- it's a little thing), and Fawn turned right around and went back inside on her own before I said a word.
