I bought a brand new HP Pavillion 17G053US from Office Depot.
It came with OEM installed win 8.
I did a fresh install of win 8.1 pro x64.
I had to do this with Legacy Support enabled, and secure boot disabled.
I used an 8 GB USB 2.0 stick for the install, the win 8.1 iso image was applied using rufus 2.3.
During the install, I reformatted the HD, removing all the OEM partitions.
I also used diskpart to convert the format of the HD from GPT to MBR.
The installation seems successful, except for a strange WLAN issue (extremely limited range despite loading the drivers).
I would also like to boot in UEFI to benefit from the faster start up times, etc.
BUT if I change the BIOS config by disabling legacy support, then it will no longer boot from HD.
The resulting error message says something to the effect of "please install an OS on the HD"
I suspected that perhaps this may be due to my converting the HD format from GPT to MBR,so I converted back to GPT, reinstalled, and still, must boot with Legacy support enabled....
Thanks in advance,
