Okay, I followed the instructions linux.com (I can't post the link yet)(the title is: Dual-booting Windows and Linux the easy way (Linux.com videos)) and now when I try to install SuSE 9.3 on the new partitions I created, it says that I can't. The installation wants to remove my first partition (WinXP) and says that I can't select "just the middle" partitions (the ones I created using GPartEd).

1st Partition: 22gb (roughly) NTFS
2nd Partition: 5gb ext3 Primary Partition
3rd Partition: 1gb Linux Swap Partition
4th Partition: 10gb (roughly) ext3 Primary Partition

the installation asks where you want to install the new system and you can choose normally. It will ask you to format the partitions where you intend to install it. You need one partition with a root label "/", one swap all others are optional like "/home" as a third.
As far as i remember you can move thru the list of partitions with the cursor arrow, then "delete" partition, then create a new one (with label "/") with reiserfs format (or ext3), and so on with the 3 partitions.
Anyway YASt wont do any partitioning until you have pressed the "confirm" button after the configuration. So give it another try.

Select Advanced Partitioning to get the partitioning program. Then you can select your new partition and select the mount point for it. It would have been better if you hadn't partitioned them and do it in the installation program.
There may be some options used when the partition is formatted, such as ACLs if you use reiserfs.

I removed the extra partitions and let SuSE install it to the detected empty space. Too many packages failed to install though and I couldn't get SuSE online so I installed Ubuntu. Which now I've got another problem. Gonna start another thread for it though.
