Details:

I install Win7 in vmware,and the firmware is efi 

I download the code of grub2 from git,compile and then mkimage like this: 

/usr/local/grub2b2/bin/grub-mkimage -O x86_64-efi -o ORMLdr.efi -m memdisk
newc normal font fat ntfs iso9660 loopback part_gpt cpio font memdisk search
linux boot chain ata pata scsi gfxterm efi_gop efi_uga usb ehci ohci
at_keyboard usb_keyboard 

but it can't boot.(It works with the code of grub 2.00) 

I type ls,there is only (memdisk) and nothing else. 

I've try to insmod every module,but it dosen't work. 

And then I found that if the module pata(or ehci/uhci/ohci) is buildin with
grub-mkimage,this will happen.

At last, I exclude modules like this,and it works:

/usr/local/grub2b2/bin/grub-mkimage -O x86_64-efi -o ORMLdr.efi -m memdisk
newc normal font fat ntfs iso9660 loopback part_gpt cpio font memdisk search
linux boot chain gfxterm efi_gop efi_uga
