Hi, recently I replaced my hard drive with a new one and then installed win 8 and now i am having all kinds of problems. I have gotten various error codes and messages saying various things. My question is should i just start all over and begin anew. If so, do I reformat the new hard drive and then try to install win 8 again. I have tried to re-install the OS alone and i still have the problems. I have multiple licenses with this Disk and i have used the disk before on other systems. So i know it is good. But i still have those problems saying things like certain files missing and certain things failed. I must say this is the first time i have replaced a hard drive then installed a new OS. So i could have skipped something i should have done like certain drivers or such. Please help i am at wits end. Thanks for any help.
