Deleteting ubuntu grub2 which is placed in sda in my asus k55v windows 8 laptop?

http://askubuntu.com – I have EFI Windows 8 in my Asus K55V laptop. EFI partition is sda1. I tried to install Ubuntu in EFI mode and selected separate boot partition as Ubuntu boot loaded. Ubuntu installed perfectly, but I got 2 boot entries in EFI setup. When I tried to delete it in EFI setup, it restored on restart. So I tried doing boot-repair, the thing is it added Grub2 to my sda partition. And it did not solve the 2 Ubuntu boot entries. So I deleted the Ubuntu partitions. Now the problem is I have the Grub2 alone installed without Ubuntu. Check this http://paste.ubuntu.com/1554147/ I need two solutions: (HowTos)
