Trying to install the latest version available of Ubuntu here with Wubi UEFI but facing the following problem.

It seems like the root cause of the issue is because I have no "device" variable in mine Windows Boot Manager

You are right. As I wrote in https://github.com/hakuna-m/wubiuefi/issues/3#issuecomment-205018636

IMHO it is better, if you set the EFI partition for your Windows as the documentation of Microsoft says.

In your case, you can use on Windows command prompt as admin:

mountvol s: /s
bcdedit /set {bootmgr} device partition=s:

After that, your device entry should be changed from unknown to partition=s:

If you unmount your partition with mountvol s: /d

the device entry should be changed from partition=s: to a Windows disk/partition name/number, something like partition=\Device\HarddiskVolume1

Thank you @hakuna-m . I will give it a try later today and update the issue with the results afterwards.
