sony vaio PCG-71314L
on turning on, hangs at "windows is starting" for ever
F10 says "disc read error"
F8 says "no operating system found"
booting/repairing/reinstalling from CD hangs at "windows is loading" for ever
what is wrong?
how could i get it to boot/repair/reinstall?
really desperate, losing all data on HDD is fine, just need to make it work again.
