Installer crashed with error in grubinstaller

As you may have noticed it let me add the other file afterwards.

Hi,
Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug was put incomplete because it does not have enough data. First, what version of Ubuntu are you installing? Have you used the CD or DVD image? Thank you very much.

Massimo by looking at the log files its possible to determine the version of Ubuntu being installed.

I was installing Mint 11 DVD via USB that was setup from unetbootin. It was being installed on a Samsung notebook model NP-QX410-J01US that was just purchased yesterday.

It failed at the same point 3 times, the 3rd time I posted the bug report. I have used this USB drive to install on a Toshiba notebook successfully.

@Brian: thanks for the suggestion.
@George: searching in Ubuntu BUG, this bug is the same of #765270, but your ubiquity is not of Ubuntu 11.04 (from which it derives), but it is Linux Mint 11 “Katya". However I am going to mark it duplicate the bug above. Many thanks.

Please do not reopen this bug. I'll unduplicate bug 817912 and handle it separately; it is in fact slightly different.

Sorry, I meant to post the above to bug 765270 ...
