Several things to consider:
Is the new PC set to look at every interface for devices - As in is the new drive connected to an interface port that the BIOS is looking at Then when you 'cloned' the drive did that include the MBR and boot block as well as having set the BOOT partition as Primary and ACTIVE Then - you are moving to a different motherboard and CPU, presumably with different buss, video, network connections as well. What I would do is adjust the partition to make space for a new OS partition at the end of the drive (beginning would be better, but that involves moving the contents of the current partition) and 'install' a new OS instance onto that partition That should show that the system will boot from the drive, and then you can 'fiddle' with it to get that boot facility to also startup windows from the copied partition. Note - the message is BOOT failed not OS failed so I presume it has not got as far as considering startup of Windows, or any actual OS. Other thoughts - unlikely to be a problem, but can the BIOS etc, access a drive of the size you are now using - What size was the original drive and partition(s) and what are the new ones?

I cloned the hdd and installed it in a quad core i5 pc. It fails to boot and give the error "boot selection failed because required device is inaccessible" 0xc000000e. I obviously want to prevent from reinstalling the OS. Is the problem because I'm going from a dual to a quad core CPU? Does anyone know? Thanks, Jimmy
