Working with an Asus A53E laptop. Enabled UEFI boot mode in the UEFI program and installed Windows 8.1 x64 successfully last night.
Now, today, when I start up the machine from cold boot, I can clearly hear the hard drive spin up and then immediately spin back down. This process repeats again, and finally on the third time, the drive stays spinning and the firmware logo appears and the system boots normally. During these "reboots", the LCD never powers on - it finally does upon the third reboot before the OS loads.
Clearly it's related to the UEFI mode. I could disable UEFI and go through reinstalling Windows, but was curious as to why this would happen in the first place, and if it really is a problem with UEFI. I would feel like this behavior shouldn't be caused directly by simply having UEFI turned on?
For a spinning drive, these reboots are obviously not the best thing in the world for it. And if nothing else, it adds considerable time to the power-on POST. Through these three cycles I measured about 20 seconds before the LCD even comes on.
Tl;dr - Why would enabling UEFI Boot mode on an Asus A53E laptop cause it to cycle through three POSTs before finally powering on and beginning to load the OS?
