PLEASE READ THE LOG CAREFULLY....actually Wubi is trying to locate some particular file in ISO file (or any source like live-usb,etc) and when it could it gives this error...I too had this problem but after reading the log and comparing it with file in the ISO, I found vmlinuz was missing its file extension(in my case it ".efi"). Wubi was trying to locate "vmlinuz.efi" and it could find it as it was named as vmlinuz. I name renamed the file...every went well then suddenly I got another error and then again I studied the log,now it was a different error. Wubi tried to copy vmlinuz in my installation directory, which now was named as vmlinuz.efi, so I made a copied of "vmliunz.efi" file and renamed back to vmlinuz.
Eureka!! It was successful.
Steps to follow(this is strictly base on study of the log. I woould strongly recommend to read the log and verify every file Wubi is searching)
- files please go to your casper directory in your installation source
- make two copies of vmlinuz
- rename one of them to vmlinuz.efi and leave other as it is.
follow these steps and your are good to go.
If you still got issues please post the log-file too.
