Unfortunately, the system image contains drivers
for the RAID0 setup, which is no longer present under the new single HDD setup. Generally speaking, you have to use some form of "re-deployment" function to restore the image to a dissimilar hardware setup.
What controller are you using in the BIOS with the new single HDD setup? IDE or AHCI?
Please refer to this, using a Macrium image: restore from raid 0 image to single drive
