I recently became interested in learning linux, so I installed redhat 9 on an old unused pc as the sole operating system, but it ran slow and I would like to try it on my current pc but as a dual boot with windows xp. this is my current setup:

p4 2.66 ghz
1 gig ram
2 hard drives (both ntfs, one with winXP installed)

now I have this extra (third) hard drive just lying around and I thought I could reformat it and devote that one entirely to my linux installation.

so here are my questions.
1) I don't want to screw up any of the stuff I currently have on the two existing drives. if I am using a third for the linux os what are the chances of me screwing the other two drives' existing data up (if any)?

2) will my redhat 9 gui installation install a thing that lets me choose my OS when i start up the computer?

3) what would happen if I then wanted to uninstall linux someday? would any of my windowsXP/other hard drives get screwed up? would the OS chooser screen go away if I go back to having just one OS?

1:Linux does't bother your other drives, especially if you have another hard drive
2:RH will install GRUB - a boot manager.. so you will be able to choose what OS you want to run
3:Linux is easy to uninstall.. you can format your hard just by doing "rm -rf /" and all your linux files will be "gone" (actually.. if you want to format your linux partition you can run cfdisk and format the Linux partition into an fat32 one)
Hope that helped
