Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Not a real problem so long as you know in advance - I've done enough of these installs to be prepared for these surprises.
After installing FC4 you might find that the Windows CD doesn't re-boot again properly -- you'll get the message System setup is inspecting your hardware and then it hangs.
Now normally this isn't a problem as dual booting from a hard disk is fine --but I needed to repair / reset the MBR (master Boot Record) which can be done from the Windows recovery console --which as you all know has to be started by booting the Windows installation CD.
This is ONLY A PROBLEM IF BOOTING FROM A WINDOWS INSTALLATION CD.
Anyway the only way I fixed this was to start a SUSE (or other Distro install) -- let it format the partitions again and then hit System Reset / reboot before continuing with the installation. --I didn't want to continue the installation but I had to destroy the /boot partition that FC4 created so I could boot from the CD.
This allowed the Windows CD to boot.
Incidentally the Windows 2000 CD doesn't need a password to start the recovery console and can access all the Windows XP files --nice security hole Microsoft .
Just a warning in case you find yourself in the same position.

yeah... that's the biggest security hole
actually those noobie hackers found out that when they have physical contact to comps they can throw it from the window(real window , not windows !) and the comp will make 3 flips and then automatically damage the computer.... PRO hackers heh?

I have been rescuing XP's MBR so often at one time that I didn't bother with the original CD but just pop a DOS bootable floppy into the drive, boot the PC up and type fdisk /mbr.
All M$ systems' booting code in the MBR are interchangeable. Do you still regard this a security hole?
Actully the reason why I used the Windows 2000CD was because the Windows XP one ASKED for the administrator password -- and even though it was MY laptop with me as the only user I hadn't a clue what the Admin password was --I don't even think there was one or theire may have been (it came with Windows already installed --I used the CD from another machine).
Windows 20000 Recovery console is a well known security gap hence the reason why people are keeping the original Windows 2000 CD's.
BTW as for recovering via a floppy --a lot of computers --especially laptops don't even have them any more.
(Sorry for the Windows stuff on a 'Nix forum --but I do know a lot of people dual boot and the recovery Console is a good tool for fixing things like MBR problems.)

It is true that Linux can see every hidden file and access a XP partition even if it is hidden.
It's not the WINDOWS NTFS partitions that are touched --it's the MBR or boot loader --after doing a FIXMBR you will still be able to boot into Windows --it will straight boot into Windows --you don't need to re-install Windows again after fixing MBR.
I have the same problem. After I installed fc4 on my labtop wondows will not boot and the cd wont boot either. When I try to boot from cd it says it is checking my hardware and then it hangs. Is there anyway to fix this problem without destroying my /boot directory; I think the problem stems from the fact that the /boot dir is first and only on the MBR.

Let's swap the situation, shall we?
Incidentally the Linux CD doesn't need a password to log in as root and can access all the files on the system --nice security hole *nix geeks.
Or if you prefer:
Incidentally the Mac OS/X doesn't need a password to log in as root and can access all the files on the system --nice security hole Apple.
Both are false; it is NOT a security hole. It is a feature.
Here's the deal:
The theory is that if a "hacker" has physical access to your box, you're SOL anyway. The ability to boot from a CD, be it Linux, Solaris, IRIX, OS/X, or yes, even Windows, and repair the system unhindered, is a FEATURE. If your data is so sensitive that you have to be worried about even a physical intrusion, you should:
1. Build an environmentally-controlled vault
2. Place your boxen in the vault
3. Encrypt the filesystems in question
4. Lock the vault
5. Throw away the combination to the vault. No, burn the combination and crush the ashes, then mix them with water
Now it's fairly secure, but not entirely unhackable.
A reasonable person would consider a machine with good network security in a locked room with solid walls to be reasonable security measures. To cripple the ability to boot from a CD to repair it as needed (or yes, to reset the root password if/when needed. I don't care WHO you are, if you work with computers long enough the time WILL come at least once where you need to reset a password) would not be an acceptable "feature"
