A few distros can boot via flash drives. Xubuntu, Damn Small Linux, Puppy Linux are the few. Puppy Linux is recommended for newbies.
Since you have burned it to a CD, you have to boot via CD and installed it on a hard disk, not external ones. Windows don't support booting via external devices except the CD/DVD.
Your hard disk needs at least 3 partitions, one for Windows, one for Linux, one for Linux swap partition (aka virtual RAM in Linux). If you don't have at least 3, there are 3 options.
1st method:
1. Boot to XP CD.
2. Follow the prompts till you reach the partitioning.
3. Delete all partitions and create 3 or more new partitions.
4. Continue to install Windows.
5. Done, boot to Ubuntu CD.
6. When you reach the stage you need to partition, don't do anything to ext1. That's Windows.
7. Check all other partitions and tick Format and install.
2nd method:
1. Just boot to Ubuntu CD and use it. It won't be installed, take time to play with it.
3rd method:
1. Get a distro that supports booting from flash drives. Puppy Linux is recommended.
If i want to go by 2nd method to try Linux,how do i make the CD readable?
Coz when i downloaded the file,i just burned it to a cd using window burner.
But neither my pc or laptop could boot from the Ubuntu CD,when selected in the BOOT first menu.
