Its a live usb with 4gb persistent.
I am able to add that parameter in nano by-
sudo nano /etc/default/grub
But the desired effect of
pci=nomsi doest occur after rebooting and after typing this command-
It doesnt have "pci=nomsi" at the end of "quite splash"
Which means system dosent booted with that parameter.
All i want is to make "pci=nomsi" permanent.
for more clarification- Previous question
