Last week I was given new Macbook Pro in my job at Leapfrog Technology
It was the exact same Macbook Pro config laptop I previously had at Leapfrog but there was no such issue like once I pressed power button it would show "Apple" logo and computer would login instantly within 5sec. But my new Mac took around 30sec before showing Apple logo and every time it booted for first time but after that every thing was normal.
So only thing I did after I got the macbook pro was using Disk Utility to make SDD's partition !
So I thought there might be the issue like bios is trying to search for the OS partition and its the timeout of 30sec which lead to boot from next partition.
So all I did was selected the "Startup Disk" from the "System Preferences"
and Rebooted in the system Partition and boom the issue was gone :]
