SuSE Linux: Versions since 7.0
You want to run Linux and Windows XP on the same computer.
Simply install Linux on the free hard disk and configure the boot loader.
First, make room for Linux. Computers with preinstalled Windows XP usually employ the NTFS file system Version 2. Unfortunately, there is no documentation available about this file system at the moment, so Linux currently cannot read or write in NTFS. Resizing the partition with YaST2's Windows resizer is not possible.
Use either a commercial partitioning program or reformat the disk. After this, you can install SuSE Linux and subsequently Windows XP.
Computers with preinstalled XP may have a separate partition containing recovery data. This partition must not be deleted!
