Hello everybody! 
Looks like I need your help - I installed ESXi 5 from CD, all is correct. But: when I reboot host machine ESXi can't start from HDD, I see message about "no operating system found". So I tried to boot from CD again and menu has been appeared: 1) Install ESXi; 2) Boot from local drive. So I choosed second option and ESXi started. How can it be? Why can't I start ESXi from local drive directly?
Thank you for answers
