So, I upgraded my motherboard from a GA-970A-UD3 to a GA-990FXA-UD3 (Rev 4.0). If you look at my post in the AMD Builds, you'd see that it was almost perfect build. After the upgrade, I tried to boot into my Mavericks installation, and get stuck on "Still waiting on root device" I made sure to set the SATA mode to AHCI like normal, and set the Boot Mode Selection to Legacy Only. I'm a bit new to the UEFI BIOS, so is there a setting that I'm missing for UEFI? I'm on Mavericks 10.9.1 using Bronya's latest kernel with Chameleon bootloader, with these flags : npci=0x2000 PCIRootUID=0 GraphicsEnabler=No. Any help would be appreciated, thanks.
EDIT: Fixed, had to set the hard drive to sata port 0, thanks to spakk for the help
