Trying (in vain, I might add) to install Slack alongside Ubuntu

Major noob trying to shoot for a dualboot ubuntu/slack setup. Not even quite sure how to form this post, lol. As far as I can tell, I did my partitions correctly. I didn't choose lilo (or elilo) for the bootloader. I'm basically clueless with grub, but I'm trying to make sense of the whole booting with grub scenario. I'm fairly certain whatever the problem is, is something I did or didn't. I just can't seem to figure out what that might be. I guess if worse comes to worse, I could just wipe my ubuntu and dedicate the whole drive to slack, but I really don't want to make that leap yet. Still too much of a noob for a dedicated slack drive, lol. The only thing I know for sure, is I get about 4 seconds into the boot process and then it just sits there. There are a couple slowpath warnings and one panic error but for all intents and purposes, I'm not sure what I'm looking at. I'm enclosing a couple pics that might help point out what I could be doing wrong. Then again, who knows? At any rate, I made this my last resort as it seems I'm not smart enough to figure this one out on my own :-/
