When I tried to install Ubuntu from the live CD start menu, the screen became black with just a blinking cursor. I rebooted the PC and I chose the option acpi=off
. Then the installer started and Ubuntu installed whitout problems.
But when I reboot the PC now after the installation was complete the screen goes black again. I am new in the use of Ubuntu.

Please add
acpi=off
to the kernel command line -- it's just slightly different than doing it with the LiveCD:Press the Shift when booting up, to get the Grub menu. Use the arrow keys to navigate/highlight the entry you want (usually the first one).
Press e to edit that entry, which will show you the details:
Find the
linux
entry as shown above, use the arrow keys to get to it, and then press the End key to get to that line's end (which may be on the next line!). Enteracpi=off
as shown, and press Ctrl+X to boot.You can make this workaround permanent by:
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
toGRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
sudo update-grub
