Hello,
I planned on installing 2 identical SME systems but couldnt even finish the first one... I bought amd x2 5000 CPU with cheap asus motherboard Jmicron and VIA for sata + 2x400Gb seagate sata drives. SME couldnt find the hdds if I connected them to VIA ports.. I chaged them to Jmicron controller and installation went just fine until I rebooted. Grub returned error 21

Could someone give me some tips and tricks to fix this problem.
Thanks!
