uninstall help

[Jake]

Hi,
I just installed Debian 2.2 version but I want to unstall and then reinstall
it.I want to uninstall it because:
1) I have win-98 on it with two partitions of 2.6 GB which I might not able
to access once LiLo is booted.Can u help me with that?
2) I am not able to configure my network in the Linux /Debian
So I thought I will have to reinstall it setting some options for me to go
to DOS -WIn 98 if I want.
Can you please help me I really need help.
Thank you,
Charles
