My Acer Aspire V5-122P-61456G50NSS, model - MS2377, has crashed all together. It came preloaded with Windows 8 and I upgraded to windows 8.1 3-4 days before crash. Unfortunately I did not make any recovery media before the crash. While accessing the eRecovery on Acer store with my PC's serial no. it says nor RCD available for this. I tried recovery by loading recovery manager (Left Alt + F10) Various other advanced startup options (like holding shift key while turning on or pressing F8 key) returns nothing but no luck. However I am able to enter BIOS. After doing research on above condition on various PC forums, now my questions: I read that a 'Windows Recovery Drive' can be made on any PC running Windows 8 and could be used to repair another PC. Does anybody in SuperUser community have that (or a link to download the same from somewhere? as I'm unable to find anybody running windows 8 among my friends). I downloaded a window 8 Pro ISO and made a bootable USB. I was able to go to 'Repair Your Computer' option and after going to 'Reset your PC' option found that my recovery partition has gone/missing. I tried all options available but no luck. Then I tried to install with that Windows 8 Pro ISO but got message: "The product key entered does not match any of the Windows images available for installation. Enter a different product key". before this message I did not got any form to fill product key! Does this mean that the installer was picking up the key from BIOS (OEM Key)? and may be the installation did not succeeded because OEM Windows version was Window 8 and I was trying to install Windows 8 Pro. If that is the case then, could somebody please send me link to download an Windows 8 ISO? I am helpless and couldn't find anywhere on internet (without having to pay for a new key, but I should not pay as the installer will use OEM key).
