Ok basically the there are 2 ribbon ports on the mobo , i have my main hard drive plugged the master socket and the other is on slave.......... but there linked up together not only on the mobo but on the ribbon cables them selfs , i have tried swapping them all round master to slave slave to master then i tried installing x-p on the hard drive it still didn't want to install windows x-p , so like i said before i tried doing the same thing on my old 60gb hard drive and i had no issues , but when i try to do it on the other hard drive i get the same blue screen saying its checking my hardware configuration , then it runs the installation process all over again .......
