I have tried several times to install Ubuntu using WUBI. I can't use a disc as I have a notebook computer and there is no optical drive.

The download and installation all seem to work well but whenever I try to boot Ubuntu at the Windows 7/Ubuntu menu, it comes up with this error screen.

Windows has failed to start. a recent hardware or software change might be the cause.   
To fix the problem:

1. Insert your Windows installation disc and restart your computer
2. Choose your language settings and then click "Next."
3. Click repair your computer.

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \ubuntu\winboot\wubildr.mbr
Status: 0xc000000F
Info: The selected entry could not be loaded because the application is missing or corrupt.

I have used both the C: and D: drivse to install Ubuntu several times each, it's always unsuccessful.

I use an ASUS x501a with Windows 7.

What do I do to fix this? I want to be able to dual-boot Windows 7 and Ubuntu.

This message indicates that the windows boot manager call to \ubuntu\winboot\wubildr.mbr failed. (It probably cannot find it). Why? Maybe you have disk encryption... Maybe some issue with the BIOS call... other?... Try installing from a USB stick instead (non-wubi). –  bcbc Oct 3 '12 at 6:53
Note it appears Wubi won't work on a full UEFI boot with GPT partition table pad.lv/694242 –  bcbc Oct 19 '12 at 19:36
