Does Compaq Presario CQ57 support UEFI?

I have Compaq Presario CQ57-425ER and want to use Windows 8.1 on GPT Disk. I made a bootable USB Flash Drive with Rufus (selected GPT-UEFI option), but my laptop can't start from this flash drive. There's a message - no bootable device. Among drivers for my laptop i found HP Unified Extensible Firmware Interface (UEFI) Support Environment.  Here is a description: ftp://ftp.hp.com/pub/softpaq/sp55001-55500/sp55477.html. I found 2 interesting points in this description: Provides support for GPT drives and Provides support for UEFI System Partition installation. I tried to launch that flash with windows on other notebook and it works fine. But in my laptop I always get the message that there's no bootable media. So, is there a support of UEFI in CQ57? And if yes, what should I do?

Yes, I know that GPT is mostly for hard drives with amount more than 2 GB. But it is possible to convert GPT all drives (even less than 2 GB). I want to use GPT because of fast booting. And if my laptop supports UEFI, shouln'd it support GPT?

Hi,

This model PC has limited support for Windows 8/8.1.  It does not support GPT or UEFI 2.3.1 or later.  It is MBR only.
