adding a hard disk after instalation (newbie assistance)

brief synopsis:

i pluged a new hdd in as my secondary master and lilo flips out, giving me L 99 99 99... crap on boot

long synopsis:

i installed slackware onto /dev/hdb1. windows is on /dev/hda1. i'm using nt loader to boot into /dev/hdb1. i duplicated the /dev/hdb1 superblock using dd command into lilo.boot file on my /dev/hda1. everything works fine. i pluged a new hdd in as my secondary master and lilo flips out giving me L 99 99 99... crap on boot. i unplug the hdd.. it works fine . i never even get to the dmseg screen so i know its nothing wrong with detecting the hdd.. its just lilo flipping out.. i went into liloconfig but i dont thing there is anything there that will help me. i tryed reduplicating the superblock but i get the same crap

any assistance will be appreciated

thanks

boot using a boot folppy and post your "lilo.conf" file contents and the harddisk partition info.

partition info

/dev/hda1 - dos - 19564 MB
/dev/hdb1 - root - 7570 MB
/dev/hdb2 - swap - 552 MB
/dev/hdc1 - data
/dev/hdd1 - iso9660

lilo.conf

lilo is flipping at boot=/dev/hdb1

you changed the hard disk right. you said you were booting with nt bootloader. do you want to do that. that is an extra step you can avoid. install lilo on to hda MBR. if you want to restore the windows MBR latte you can do that using the windows cd.

change the line boot=/dev/hdb1

make it boot=/dev/hda

save the file and run "lilo" in the command prompt.

all the best

thanks for the comment.. but my way works fine... the config is great and i can boot from it (as a matter of fact i did just that to get the lilo.conf file you requested). the only problem is when i add my third hard disk to sec-ide master (/dev/hdc1) lilo flips

just as referance i'm not even sure it is lilo... i get into nt loader and it boots to windows fine with that drive in but when i go into linux to load lilo it flips..
