I have the same problem as well. I am on Windows XP SP3 on my office PC, but can't boot off the CD due to BIOS password restrictions and a hard-disk-first boot order.

When I ran the wubi.exe executable from the Live CD, it got to the point where it tries to install the boot manager (which is supposed to help me boot a Live CD using some clever trick), but it fails with the same error as above. I attach the log file wubi-11.10-rev241.log.

When I ran a standalone version of Wubi with the CD still in the drive, I got the same error, but with a slightly smaller log file (wubi-11.10-rev245.log)

These errors are very confusing and means that - in order to get help - they either have to be able to read and understand the Wubi log file, or post it somewhere for someone to read.

These problems are caused by coding bugs. Wubi needs to exit when it encounters the 'salient' error e.g. "ISO is the wrong size". Rather than setting the attributes to "None" and then continuing to try something new. It eventually is encountering some code that expects the attribute to be set, and throws the exceptions. At least this is my analysis.

These new confusing messages were introduced in 11.10 - probably when the preinstalled image install was introduced.

PS here is a link to a partial log file where the latest message I added was taken from:

I just wanted to clarify this. The message: 'WindowsBackend' object has no attribute 'iso_path' occurs when installing Wubi and there is something wrong with the CD.

The message: 'WindowsBackend' object has no attribute 'cd_path' occurs when using the CD boot helper (to use Wubi to help boot a live CD).

These are two separate tasks, so probably should have two separate bugs. I have a one line fix for the first, but it's still unsatisfactory because it still goes on to fail with the end message being that it "Could not download the metalink therefore the CD etc. " If it is going to 'keep going' with the install after finding a bad CD, fine, but if it's always going to fail then it should do so with the relevant message i.e. bad md5sum or size mismatch etc. So I'll investigate that some more. When I've got something I'll create another bug and attach my results there.

The CD boot helper is used less commonly. It's easy enough to fix the meaningless error message by making sure the attribute is defined, but I haven't got it to complete successfully after that so there's a little more to the puzzle.

I've just tested this fix on the current daily...
1. burn cd from latest precise-desktop- i386.iso
2. boot into windows, insert the CD
3. select 1st option "Demo and full installation", then option 3 "Help me to boot from CD"
4. Everything runs - only confusing bit is that it Ejects the CD at the end and instructs to reboot to complete. This is true for a normal Wubi install, but not for the CD boot helper, which requires the CD in the drive.
5. Reboot, select Ubuntu (running on XP, not sure if Vista/7 will auto boot into Ubuntu)
6. Another confusing bit: it gives the 5 second countdown with the message "Completing the install, press ESC for more options". This is appropriate for the normal Wubi install, not the CD boot helper.
7. It boots from CD, direct to the live desktop.

So, in summary. The fix restores the previous functionality of the cd boot helper.
(The confusing bits are already reported in bug 759352 )
