I recently tried to install Ubuntu 13.04 on my laptop (Lenovo IdeaPad S300 - rather standard stuff including Intel Core i3 and Intel HD3000 graphics - UEFI enabled).

The process goes fine, but at the very end of the installation, when the pop-up window says it's time to restart the computer, the screen just goes blank when I click "Restart" and the computer will not restart. I never experienced this before (install ok for 12.04 and 12.10).

I tried again several times, checked my iso, but the behaviour is always the same. When the screen is blank, if I force shutdown by keeping the power button pressed, the computer then boots normally and the installed system looks somewhat fine at first glance ... Is that a known behaviour?

Thanks for your help, Didier

When you say "the installed system looks somewhat fine at first glance," do you mean that it works normally in both Linux and Windows? What happens when you reboot or shutdown from the installed system? If I understand correctly, re-installing Linux won't help. If the installed system reboots fine, don't worry about the failure to reboot immediately after installation. If you have ongoing problems with rebooting, you may need to adjust the options passed to the kernel at boot time, but you'll need to post more details about the problem. –  Rod Smith Jul 9 '13 at 16:56
Hi! There is no Windows system alongside. And indeed, the linux system that was installed looks ok: I've not been using it for long but things seem to work, the computer can reboot or shutdown properly. I'm just a bit concerned because of the "forced" shutdown at the end of the installation process: isn't there any risk some file system errors occur if it wasn't properly unmounted ? Thanks for your help ! –  Didier Jul 10 '13 at 9:21
There is a risk of filesystem damage whenever the system is not shut down properly; but if it comes up OK after such an improper shutdown, I wouldn't worry too much about hidden problems. Although a hidden problem could be lurking, it probably is not. –  Rod Smith Jul 10 '13 at 13:51
Thanks for your valuable feedback. In case something shows up after some use, I'll update this threads. Cheers! –  Didier Jul 10 '13 at 15:15
