BTW, this reviewer's experience installing a current version of Netrunner gives some idea of what I went through (scroll down to the section, "Installation - Prepare to suck", first paragraph). My experience wasn't nearly as bad as his, but the installer leaves a lot to be desired.

You can also write zeros to the whole drive, but that takes forever and doesn't accomplish anything more, IME.

I don't really understand the problem. But, to remove the master boot record simply do:

Code:
dd if=/dev/zero of=/dev/sda bs=446 count=1
...as root (under Linux) on said machine. Replace "/dev/sda/" with whatever your harddrive shows up as. It could be "/dev/hda" etc instead.

Make sure you type this exactly correctly. The "dd" command can very dangerous.

To remove the different partitions, use the "fdisk" command. This can also be very dangerous.

I accept no liability if these commands cause you problems, but these are the tools I use at least once a month to do what you are wishing to do.

That's not what he wants to do. He wants to remove one of four OSs and its partition, while leaving the other three intact, and updating the bootloader to remove the entry for the fourth. What I suggested is a way to do that; completely removing the bootloader is a good way to get yourself into endless trouble for no reason whatsoever.

Perhaps a more cautious variant on the theme I proposed is to, under Netscape 12, modify the grub config files to remove the entry for Netrunner 16, then run "update-grub", and reboot to verify that the booloader entry for Netrunner 16 no longer exists. Then its partition may be safely removed via however method (I would suggest a live disc).

Ah, thanks. I misunderstood the desire. Doing what I showed definitely won't achieve this....

Sounds like a plan. I'll try that method first. If you hear desperate wailing off in the distance, you'll know I screwed it up.
