装linux顺着install CD指令就行，双启动

It is 10+ pages instruction, so post your question/problem after you read linux online document. Major steps are:
1 disk partitions
2 select software component, such as Work Station, etc
3 Create root acount
4 Set boot loader

If you want to dual boot, configure lilo to boot either to linux partition and XP partition.

Install Linux and XP in seperate disk so that one doesn't corrupt the other during installation.
