Checklist The default "Desktop" installer requires 384-800 MB of RAM (depending on your selected options.) If you have any problems, or if you're comfortable using a keyboard interface, try the alternate installer to install on computers with less RAM or a hard disk smaller than 4.3 GB. Check MD5SUM for the downloaded ISO - You will need to compare your MD5SUM with Ubuntu Hashes . Burn the CD OR create a bootable USB flash drive - using UNetbootin is highly recommended Check USB or CD Disc for Errors. When you boot the default installer, you will see the option to "Check Disc For Errors", otherwise, check for errors manually .
