Macrium Win PE Rescue disk booting

My laptop is acer aspire V5-571P-6815 bought recently a few days ago. It has EFI-GPT booting and partition system. It does not give recovery disk making facility from DVDs. I used macrium reflect and taken total disk images in external usb HDD. I also made Macrium Windows PE rescue disk using marium reflect.
My laptop has two boot modes : 1)UEFI 2)legacy BIOS mode.
Windows 8 boots only in UEFI mode.
Where as Macrium Windows PE rescue disk does not boot in UEFI mode, but boots in Legacy bios mode.
I want to know from experienced users whether this is normal? From there will I be able to recover my windows using Images created?

In UEFI/GPT system, how to shrink Windows partition which has 686 gb (free 650 gb) and make additional partitions?

Did you make the OEM manufacturer's Recovery Disks?

We always assume you have made your Recovery Disks using the OEM manufacturer's Recovery Media Creator app the first day you had your new PC.
& made the Startup Repair CD.
