What is EFI mode? And how you much windows 8 costs to you? Have you purchased your dv6 before 2 june?
UEFI stands for Unified Extensible Firmware Interface (You can read all about it here
Since WIndows 8 support secure boot functionality, Installing the OS in UEFI mode will have lot of advantages like faster boot, enable boot >2.2TB, protection from rootkits etc.
So anyone why there is not option to enable UEFI boot in our BIOS? Did HP disabled that?
Coming to Windows 8 question, i have not purchased it yet, But it will cost me Rs. 1999 since i brought it in October last year.
