id summary reporter owner description type status component version resolution keywords cc guest host 1676 Guest cannot boot from SATA port 4 => use VBoxManage Zach "It appears that in both my Linux Host as well as my Windows host using Virtualbox 1.6.2 I am unable to boot when the primary disk is set to SATA port 4 (non IDE emulated SATA AHCI). The error that appears: '''FATAL: Could not read from the boot medium! System halted.''' Hitting F12 shows no hard disk detected. However if I change the port to SATA port 0 (IDE Emulated) then the machine boots fine. Also note that I created a Virtual Machine along with a new image with the same result. Attached is the log file for reference/review from my Linux host. I can supply the Windows Vista host log file as well if required. " defect closed other VirtualBox 1.6.2 fixed other other
