Need help with installing OpenSUSE 13.1 on pre-installed W8.1

Hi there,

I'm new to linux and currently have a HP Pavillion G4 2203-tx with Windows 8.1 pre-installed. I've tried to install OpenSUSE in dual-boot configuration with Windows 8.1 using a 8gb flash drive (created using Rufus) in UEFI. Everything was fine until the partitions scheme.

My requirement:

- keep W8.1 intact with UEFI and capability to boot (i'm using dreamspark version)

- OpenSUSE get installed and co-exist happily with Windows.

Steps i've made:

fully updated w8.1 and all hardwares' drivers (BIOS included)

My hard drive is a 750gb hdd. i've split it into 6 partitions, the first two are created with the installation of w8.1:

- system reserved: 350mb
- C:\ holds the w8.1: 120gb
-/boot partition for opensuse (ext4 formatted) : 20gb
-/home partition for opensuse (ext4 formatted): 20gb
-/swap partition for opensuse (linux swap formatted): 5gb (i've 4gb RAM)
-the rest is left unformatted

i've turned secure boot and hibernation of w8.1 off.

The installation went perfect until the partitions scheme. i've mounted the linux partitions as their intended purpose but YaST kept telling me that i've not mounted an /efi partitions (FAT format) and said that the installation is going to crash fatally. It did.

What i'm suppose to do with that /efi?
