Desktop Video, Display and Touch

It started with a PXE issue. i got the message on start up, all of a sudden

Checking  Media Presence

Media  Present

Start PXE over IPv4

And then nothing. The message just stay here on the screen and won't proceed with anything. Restart would bring it up again in 3 cases out of 5. Googled it up.

I disabled secure boot, enabled legacy boot, checked boot order, disabled network boot completely and everything become ok for a while.

Anti virus scans showed nothing, but overall performance become a bit pure.

Anyway. After a while, got the following message:

no boot disk has been detected or the disk has failed

I performed the hard drive tests via HP diagnostics, but everything was marked as PASSED and no error occurred.

I then reseted the BIOS setting to default and restarted my PC.

Then have tried the "refresh your PC" option but halfway through got another error about invalid secure boot signature or something. 

BIOS->Disable Secure boot/Enable legacy boot and upon restart i got the PXE error telling me that No Boot Filename Received. Disabling my adapter in boot order would bring the "No boot disk has been detected" error, predictably. 

So, currently, i am unable neither to reset Win 8 or to boot at all.

I can't recall whether i got a Win8 disc with my PC or not. At least i can't find one 🙂

And i don't have a recovery disc either.

Any help would be much appreciated.
