Sagar_R's questions

I need a reliable application which will make usb pen drives bootable. Recently, I tried creating a bootable lubuntu-13-04-alternate usb on a ubuntu 12.10 system but ended up with 'boot error' when trying to boot. I tried startup disk creator as well as unetbootin. This is not the first time I am experiencing this, rather the above two utilities have always had high failure rates in my experience. Universal-usb-installer, YUMI, LiLi have worked great whenever I tried them, but all of them are windows only! So I have two questions:

1. What is the method to reliably create a bootable usb in ubuntu?
2. Why does windows have some of the best bootable usb creators while linux dosent?

I have 12.04 running on Intel dual core with Nvidia 8400 GS. I had installed the post-relase updates for Nvidia, but encountered some problems, so removed [deactivated] them through "Aditional drivers".

After restarting, when I went to install the recommended version current drivers through "Additional drivers", I get the following error:

Sorry, installation of this driver failed.

Please have a look at the log file for details: /var/log/jockey.log
