I'm badly and urgently in need of help. I just "sanitized" the
hard disk of my HP Compaq 6720s laptop and now I can't boot up.
The process starts and after "initiating and establishing link",
it says "PXE-61: Media test failure, check cable", PXE-MOF:
exiting Intel boot agent" then it goes to "Non-System disk or
disk error, replace and strike any key when ready"
I tried booting from CD cuz I wanted to change OS but when it
gets towards the end it says "acpi.sys damaged" then asks me to
strike any key to restart computer. I'm at a loss about what to do!
