In some cases it is interesting to make the complete installation in text mode. Sometimes I have found it impossible to work with mouse (life seems to move) during setting of a machine in a Blade (do not know if it will be for the browser configuration or Blade …).
Anyway in these situations it is better to install in text mode and ready. This can be forced in the first welcome screen during installation, if we get above “Install or upgrade an existing system” and press tab appears:
Then we added at the end:
vmlinuz initrd=initrd.img text
And press return and gotten.
