Greetings,How do you burn Tar files to CD, so that i'm able to boot up from cd.thanks ...

Multi-session CDs or DVDs allow you to use the disc several times. You burn some files, take a break, then burn more files on the disc’s remaining space. You can burn several sessions onto the disc.

Using one of these programs will allow you to check and modify the contents of the file before you burn it to a disc.
