Greets, :-)

Recently I installed yellowdog linux and then uninstalled it.

After the uninstall the yellowdog boot loader remained (no problem) but it would not boot to a cdrom. :-(

I then installed ubuntu 7.04 to remedy the issue with the boot loader not booting to a cdrom.

The issue remained. :-(

Is there a distro that one can install that addresses potential issues with the boot loader after a uninstall?

I assume it is best to install the boot loader off the mbr, if so how difficult is this for an average linux user?

Mac Ibook, 1.42 GHz PPC G4, 60 gig, 512 ram...

Any input or information is appreciated. :--)

Well most of your problem, I know nothing about - i.e. no knowledge/experience with Mac's etc, but it's quite normal too install the bootloader to the MBR because otherwise it can be a bit of a nuisance to boot the installed OS, of course if you installed the distro to the entire hard drive, then it's concievable that you'd need to wipe the MBR seperately, though that'd probably be accomplished by installing a new distro over the top - dual boots often have the ability to "re-install the xxxx bootloader" i.e. when you boot a CD but go for a rescue option, thats when you have the choice of re-installing the original bootloader - I'm making the presumption that this would happen with a distro for Mac in a similar way that it does for PC based ones.

Might it be the case that something has altered in your BIOS ??? so that it needs amending to be able to boot from a cdrom again ???

Sorry if that's not very helpful, but it's all that I can think of right now.

Try KNOPPIX or Puppy Linux because those are designed for recovery/debugging.
