Wubi

Error Message whilst installing Ubuntu 11.10

Asked by Matt Port

I get this error message whenever I try and install the boot helper for ubuntu using wubi:

       "an error occured:

       'WindowsBackend' object has no attribute 'cd_path'

       For more infromation, please see log file............"

I looked at the log file and it said this:

            Traceback (most recent call last):
            File "\lib\wubi\application.py", line 58, in run
            File "\lib\wubi\application.py", line 130, in select_task
            File "\lib\wubi\application.py", line 205, in run_cd_menu
            File "\lib\wubi\application.py", line 122, in select_task
            File "\lib\wubi\application.py", line 228, in run_cd_boot
            File "\lib\wubi\backends\common\tasklist.py", line 197, in __call__
            File "\lib\wubi\backends\common\backend.py", line 537, in use_cd
            AttributeError: 'WindowsBackend' object has no attribute 'cd_path'

I don't know what to do and wonder if anyone else has had the problem - i get the same whether i try to use a USB or a CD-R, any suggestions??

Did you MD5 test the ISO you downloaded?
Have you tried mounting the ISO using magicdisk or daemontools?

I have done an MD5 check and it came out fine... also, what would be the
benefit of mounting it with either of those programs?

Mounting it means you don't need a CD or USB stick, the data can just be read and wubi can be used from there

Remove the CD and USB from the computer. Download wubi.exe and place in same folder as the desktop CD ISO you downloaded. Run wubi from there.

Usually the problem is from a bad CD (bad burn).
You can't run wubi from a USB unless it's a very small partition (~ < 840 MB)

I have already answered for a similar question but I repeat my answer here.
This error is not a CD burn error because when I used the CD on my old laptop running under Windows XP it worked fine.
The error comes from WINDOWS 7 which is loaded even when a CD is put in the CD/DVD drive. It is one more attempt from Microsoft to force you to stay on WINDOWS !!
So when you restart your computer press the F12 Key and maintain it pressed until you get the boot set up menu where you can choose to boot from the cd.
After that I was able to install UBUBTU 11.10 next to WINDOWS 7.
