I strongly recommend you to visit this link to install ubuntu proprely :-
I know how to install the ubuntu os. Ive installed it as a guest operating system in windows vista. The only problem is that the sound card of my laptop is not working well with this os. How could I check which kernel of linux would support my sound card.
Name of sound card is IDT.(and I currently dont have an internet connection)
1. copy-paste the following command into the Terminal:

gksudo gedit /etc/modprobe.d/alsa-base.conf

2. and add these lines to the end of the /etc/modprobe.d/alsa-base.conf file:

# Keep snd-pcsp from beeing loaded as first soundcard
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=dell-m4-1
options snd-hda-intel enable_msi=1

3. Then navigate to System>Preferences>Sound and change everything to ALSA

4. copy-paste the following command into the Terminal:

gksudo gedit /etc/group

5. replace the following line (or something very similar to it):
