Hi Im a Digital Forensics student in first year and we are to get familiar with linux and Backtrack. I have used Ubootin and installed the Backtrack 4 R version iso on a 4GB memory stick.

I changed the root bootup settings in BIOS and managed to get to the menus screen for back track but whatever version i choose i always get the same errors when it tries to load. Something along the lines of I/O error in memory buffer 1,2,3,4 etc and keeps repeating.

Any advice would be helpful Is it because I shopuld have used an 8GB Usb stick?
