I want to run Windows 10 and Ubuntu 16.0.4 as dual boot with Windows being encrypted by BitLocker and Ubuntu with LUKS. I have been able to achieve this on BIOS using following:

How can I install Ubuntu encrypted with LUKS with dual-boot?
But, somehow it does not work with UEFI with respect to Ubuntu. I am facing issues with GRUB I suppose. Initially I faced the issue of EFI Partition not found as guides are for BIOS-based solution. But, then I created efi directory in /mnt/boot and mounted it against the EFI partition where Windows Boot Manager is installed. After that I specified the Windows Boot Manager (EFI Partition) when running grub-install command and everything went fine without any errors. But, when I reboot, I am given initramfs prompt. So, quite not sure how to troubleshoot it.
Steps that are not in the guide and I have done are below:
mount /dev/mapper/ubu-root /mnt
mount /dev/sda1 /mnt/boot
mkdir -p /mnt/boot/efi
mount /dev/sda2 (Windows Boot Manager) /mnt/boot/efi
cd /mnt
mount --rbind /dev dev
mount --rbind /sys sys
mount --rbind /run run
mount --bind /proc proc
chroot . /bin/bash -l
blkid (to note down the UUID of /dev/sda6 (luks volume))
vi /etc/crypttab
sda6-crypt /dev/sda6 OR UUID none luks,discard
:wq
update-initramfs -u
grub-install --recheck /dev/sda2
grub-mkconfig -o /boot/grub/grub.cfg
exit
cd
umount -l /mnt
sync
exit
exit
Any help would be appreciated?
