I've downloaded Gparted 0.12.1-1 and burned it to DVD. What would be my next step to accomplish what we want to do? Do I just stick the disk in the drive and see if it boots to Gparted? If it doesn't boot, do I change the bios to boot from CD and then try?
Exactly. The CD/DVD drive must be before the hard drive in the boot sequence.
Once Gparted is running, how do I proceed? Do I find the Fedora partition and just delete it and then then stretch the Windows partition to the full size of the disk? Is there anything I have to watch out for?
You can either delete the fedora partition and grow the xp partition to take the disk space, either just format it in some file system that xp is able to use and use it as a data partition (it will appear in xp with a new letter).
The second method is much easier and faster. The first one offers a single disk space.
It is very probable that there are 2 partitions for fedora: one for the system it self and another one for swap (1-2 GiB). This is usual in Linux systems, although it is possible to have a setup with no swap partition or with a swap file. In this case, you have to delete both. If there is any extended partition that contains them, you have to delete it, too.
To resize the xp partition (usually ntfs) be careful to select the option Nothing or No align in the Align box. Furthermore, don't touch the start of the partition. Just, drag the end of the partition to the right, to the end of the drive space. Trying to resize with an align option other than the actual one will break the boot process (it is possible to repair it with the xp install cd, however it is better to avoid the problem).
I'm not totally new at this stuff because I partitioned hard drives in DOS 3.3, but I've never tried Gparted and don't want to screw anything up.
The DOS3.3 fdisk was quite simple. It asked just for the % of the drive to give to each partitions. The unix fdisk was quite more complex. GParted offers graphical use for the various tools, although in some special cases we need to go back to the command line.
Don't try to stop a running operation. A broken resize can be harmful foe the data integrity.
It is safer and recommended to keep backup of any important file of the hard drive. In most of the cases there is no problem, however there is always chance that something happens: hardware failure, power break, bad setors, defective connections or cables... as well as file system problems, software bugs.
In case of dubt, you can post here a screenshot of GParted and the output of the command
sudo fdisk -l -u
(l is the lowercase L) from the terminal window, for additional advice.
The GParted log stays in RAM and goes away after shut down. So, to keep the content you have to press the Save details button at the end of the operations to save it in html format and then copy it from the RAM to an external medium (USB stick, floppy disk... ).
Look for "Saving GParted details" in the GParted live manual.
*** It is highly recommended to backup any important files before doing resize/move operations. ***
