I posted another question about installing to USB HERE which I tried because I couldn't get this to work. My original problem is I can't get ESXi 4.0 Free to boot from my LSI 8308elp RAID controller. I'm starting two different threads because they're two different problems. My problem here is I can install ESXi to the RAID with no problems, but when I reboot I get 'Failed to find boot partition' after vfat is loaded. In checking the boot log I see that drivers for the raid controller never get loaded. The controller is on the HCL. Anyone know what I can do to get this working?[t-267609]
