Removing HDD with Linux

I have Linux Mandrake 8.0 on a 6 GB HDD. I also use Win98SE on a separate 20 GB HDD. How on earth do I remove the Linux HDD, put a different HDD instead and boot up Win98SE?

I've tried this by removing the 6GB HDD, putting a 4 GB HDD instead and booting. It won't boot. LILO won't load.

I used a Win98 bootdisk to get to DOS, then tried to go to Win, but it started with a blue-screen-of-death and a nice VFAT error message and locked up.

This is no biggie problem, but I'd like to use the 4 GB HDD as a "removable" HDD for tranportation and such.

Thanks in advance.

AMD Athlon 1 GHz
MSI K7T Pro 2 (VIA KT 133)
512 MB Ram (133 MHz)
20 (Seagate) + 6 (Maxtor) GB HDD
SB Live! 1024
Win98SE/ Mandrake Linux 8.0

Here you go. First make a boot disc from linux with lilo on it. Then go to winblows then make a boot disc on it and then boot with it then run type at the A prompt: fdisk /mbr
Then when ever you need to run linux just boot up with linux boot disc. If yuo dont use boot disc from linux, your winblows disc will boot up normaly under winblows. Don't know about your BSOD troubles, sorry. Now if you want to get rid of linux completely (please don't give up) just do as I said, and then boot with windows boot disc, then type at A prompt: fdisk
then choose "Change current disc" then reformat it to a "Primary partition". Then set it to "Active", then you can boot into win, then format it to FAT and you are all set to go and all your BSOD fun ;-)

OK, fdisk /mbr wont hurt a thing. All it does is set the master boot record (mbr) to use windows and niot any other boot manager. Well, let me boot into linux and find the exact proggie to make a linux boot disc. I'm a relative noob to linux, but I have had lots of experience in installing it and messing around with a hard drive :-)
