New SSD. Unable to use with AHCI mode.

I think you may have misread a large portion of my original post.
Cloning the HDD over to the SSD then taking out the HDD and booting off the SSD with no BIOS changes gives me "Operating system not found".
Trying to install fresh with no BIOS changes (AHCI mode) tells me "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."
I can install Windows while in IDE mode, but when changing it using the method you linked I get "Operating system not found" again.
All form of recovering the boot environment gives me "Requested device unavailable" and automatic system repair gives "No OS files found".

As an added note, the SSD is not showing up in boot devices while AHCI mode is active (Though BIOS shows it on a SATA port) only when in IDE.

Woah not that one. This one:
OCZ Arc 100.

Nope, not using one. It has not been set.

Please try dsissabling SpeedStep, i know it causes problems for Dual booting with Ubuntu.

The password hasn't been set so the options are greyed out. I double checked and it is definitely asking me to set one as well as not letting me choose any other options other than what is highlighted in the screenshot.

Thanks. I am afraid that has made no difference though. Still can't get the SSD to appear in the boot menu with AHCI.
