This article is the best that can be found on the internet.

I am writing to inform people that if they miss an important step the installation will not be completed.

The step is:

Now your /dev/sda2 will be offered to be install partition, ‘Select’ and then select ‘Format’ and then select file system ‘resierfs’.

This step is a must. You must format your partition before proceeding otherwise you'll encounter error in the installation process.

Good luck to everybody and thank you very much for the article it saved me much time.
