Resizing an NTFS partition
Note: Please ensure you have a backup before attempting this.
Most systems that are purchased already have Windows XP installed on it, and most people would prefer not wipe it off completely when doing an Arch Linux installation. Therefore, it is useful to resize the existing windows partition to make room for a Linux partition.
System Rescue CD is a good tool to have, and works seamlessly in most cases.
- Download the CD image (from http://www.sysresccd.org/Main_Page)
- Burn the image to a CD
- Boot from the CD
Once booted, run qt_parted and the rest should be fairly obvious.
If you already have Arch Linux installed on your system and simply want to resize an existing NTFS partition, you can use the parted and ntfsprogs packages to do it.
