I've Ubuntu 14.04 Host machine with Virtualbox installed.
I've a SATA hard disc with windows 10 installed. I want to boot into the windows OS via a virtual machine created in my Ubuntu server.
parted -l
output is as below:
Model: ATA ST1000LM024 HN-M (scsi)
Disk /dev/sdc: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt

I've created the rawvmdk file using the following:
VBoxManage internalcommands createrawvmdk -filename "/media/wde/VirtualBox VMs/Lenovo_Org_Win10.vmdk" -rawdisk /dev/sdc -partitions 2,4,5,7
As per the askubuntu question, I mounted the EFI partition and created the ISO image as follows
mount -t vfat /dev/sdc2 /media/winhd/
grub-mkrescue -o boot.iso winhd/*
EFI drive has following things:
root@p:/media/winhd# ls
BOOT BOOTSECT.BAK EFI snapshots
root@p:/media/winhd# ls BOOT
boot.sdi
root@p:/media/winhd# ls EFI/
Boot Microsoft ubuntu
root@p:/media/winhd# ls EFI/Boot/
bkpbootx64.efi bootx64.efi
root@p:/media/winhd# ls EFI/Boot/b
bkpbootx64.efi bootx64.efi
root@p:/media/winhd# ls EFI/Microsoft/
Boot Recovery
root@p:/media/winhd# ls snapshots/
control_{00000000-0000-0000-0000-000000000000}.dat layout_{00000000-0000-0000-0000-000000000000}.dat snapshot_{00000000-0000-0000-0000-000000000000}.dat
root@phanuis1:/media/winhd#
I added the ISO image in CD of the VM, added vmdk file as the harddisc, and when tried to boot, I am getting a screen with following message:"Minimal Bash like line editing supported…" and grub command prompt is displayed!

I don't know why that happens, but you should be able to boot Windows by running these commands in order:
(hd0,2) here is the refferer to the EFI partition Also make sure to enable EFI boot, but from your Question I can see, that you probably do.
