Fedora Core gone

As I thought, Partition Magic would not let me resize the Linux ext2 partition. I took one look at the Linux command line tool for resizing partitions, GNU Parted, and decided that deleting the partition and reinstalling Fedora Core 3 Linux would be my best option. Then Partition Magic gave an error when I tried to delete the Linux partition Error 510: "The version of the file system is not supported". Great. The Partition Magic support site says:
"Norton PartitionMagic 8.0 and PartitionMagic 8.0 may not work with Linux Ext3 partitions when the dir_index file system attribute is enabled. Recent Linux releases from Red Hat and Fedora set the dir_index file system attribute by default. To prevent the error, disable the dir_index attribute, perform the partition modification, then re-enable the attribute.
To disable the dir_index attribute
1. Boot into Linux single-user mode."

Okay, now I first had to figure out how to "Boot into Linux single-user mode"
A quick web search picked up the answer "How To Boot Linux (Red Hat Fedora) Into Single User Mode Using Grub".

A few minutes later the linux partition was gone - I had to re-format it in Partition Magic before I could delete it, but it worked.

Now I need to reinstall Fedora Core 3 Linux.
