Harry, I was just checking documention on deleting the linux partition using FDISK. Apparently, you're supposed to delete only the Non-DOS partitions? I checked using FDISK and this is what I have:

Part---Status---Type--------MB---Sys
C: 1---A--------PRI DOS---2408---FAT32
2----------------Non-DOS---620
3----------------EXT DOS---1090

The EXT DOS partition contains logical DOS drives. when I displayed the logical drive info, it showed, 'No logical drive defined'.

FYI: Un-Doing Dual-Boot Using FDISK on Windows 98.
