I somehow formatted the OS drive so now when I try to install windows 7 on my Asus k43s laptop (boot via DVD) I get the " I/O unexpected error, error code: 0xc00000e9 " I tried win XP and 8, same error, I guess I need some recovery partition/dvd to boot it, can someone confirm?
I read on some forums to press F9, but doesn't work. I even suspected the health of HDD, then booted with a portable os and checked drive c and it was ok.
