upgrading Ubuntu 11.10 to 12.04 LTS

Does the system have a make and model?
What video chip do you use?
Do you use proprietary video drivers?
Thanks

Thank you for looking into my query.
The system is Dell make, model Dimension-2400; the processor is Intel Celeron CPU 2.40 GHz.

Kindly advise how to get the required information, if possible.

Would this require resetting the kernel boot options. In which case the current frozen restatr has to be aborted.
Kindly advise, if possible.

Hello,

Usually when the restart comes, the upgrade should be completed. I guess something else creates this problem with frozen startup.

Abort the current frozen startup and try one more (reboot).

Also check the
nomodeset option as @actionparsnip said. Just for login and then uninstall the proprietary drivers and install them again.

Thanks actionparsnip, that solved my question.
