I tried to install Linux on my second computer.  I deleted my
partitions and created a new partition.  I had a completely clean 1
gigabyte hard drive with only one partition, a primary DOS partition.
I installed Linux Mandrake from a CDROM disk that was in a Linux
magazine that I purchased.  

I could not do anything properly because I did not know how to use
UNIX commands.  I decided to get rid of linux and reinstall win 98.  I
tried to delete the partitions using FDISK from my win 98 startup
disk.  I couldn't do it.

My win 98 startup disk indicated that my hard drive was partitioned
into a Primary and extended DOS Partition.  When I try to delete the
extended partition I get a message "cannot delete extended partition
while logical drives exist."  When I try to delete the logical drives
I get two  messages.  The first says "no logical drives defined", the
second message says "all logical drives deleted in extended 
DOS partition".  I go back to trying to delete the extended partition
and I get the same old message,  "cannot delete extended partition
while logical drives exist."  

Any ideas?  All help will be appreciated.  Thank you,  Richard
