Moving a Wubi install to a different Windows 'drive'

Question

I was wanting to move my wubi install from drive E: to C: as to have a working backup location that is not on the drive which I will be migrating to a regular install. (I want to make the E: drive a Linux partition.)

I read moved ubuntu folder from C: to D: drive how to correct UUID entries and How to convert Wubi install into regular install? for migration at another time.

And, I tried to figure out were my grub.cfg file is. The only thing I found was an empty grub directory, and did the following. By going into Windows renaming the Ubuntu folder to Ubuntu-test and tried to reboot into Ubuntu. What I got was an error message with a File: \ubuntu\winboot\wubildr.mbr with the status: 0xc000000f. I rebooted again and went back to Windows and renamed the folder back to Ubuntu. Back to the same Ubuntu with all of my settings and configurations.

I also copied all the files and folders in E:\ubuntu to C:\ubuntu before this renaming and un-renaming above. So the question is: What do need to do in order to move this to C:?

On XP it runs C:\wubildr.mbr. On Windows Vista/7/8 it runs \ubuntu\winboot\wubildr.mbr on the drive you installed on. So moving the Ubuntu folder to a different partition will give you a wubildr.mbr is missing or corrupt message like you saw.

You can just edit the BCD store directly by going to a command prompt (CMD.exe, making sure you select Run as administrator) and then changing the Ubuntu entry:

bcdedit /set {uuid} device partition=C:

(You have to figure out what the uuid is, by first running bcdedit and copying the one that shows for your Wubi entry. e.g.

C:\Windows\system32>bcdedit

path                    \ubuntu\winboot\wubildr.mbr
description             Ubuntu

C:\windows\system32>bcdedit /set {1476af63-e5bc-11de-b180-0024543ae029} device partition=C:

Any BCD changes have to made while running Windows or booting to a Windows repair prompt.

That all looks like it needs to be done in Windows. Can it be done in Ubuntu also? — user160140, May 31 '13 at 07:17
Had a small problem, which took me a few days to figure out. I was starting to do the second thing stated above, the migrate, which meant that I needed to make the E: drive a linux drive. After using Gparted, I found out that I did not have my Grub correct and had to use Windows to find https://answers.launchpad.net/wubi/+question/186778 which fix the problem. I think the line "sudo update-grub" is what I did not do or needed to do in the first place before I even started on the migrate. Is this correct? — user160140, Jun 04 '13 at 01:02
