How do I safely uninstall knoppix from HD?
 

I put Knoppix on a laptop alongside Win7 and Ubuntu. I tried to password protect grub to make knoppix secure, but to no avail.

How do I remove Knoppix without affecting the other OSes? The grub bootloader was installed by Ubuntu, so can I just wipe the Knoppix partition and update grub to remove the entry?

Much obliged.

Yes and yes, if your bootloader is grub you can simply remove the entry. You can then reformat the partition or do whatever you would like with it.

You also can use your Windows 7 dvd to fix the loader.

To remove linux you delete the partition(s) and expand your windows 7 using storage mmc in windows.

Do i remove the entry first or format first?.....or does it not matter?

Remove the entry from GRUB first!

Since I'm a noob, I think I'd better also ask advice on the proper way of removing the entry from grub. Is it only the boot/grub/menu.lst that I must edit? If so, which parts? I believe this is the one of the files I attempted to alter when I tried putting passwords on the Knoppix entry which royally messed up Grub :/

Now you're adding a new dimension to the problem. If you have a recent version of Ubuntu and use its Grub bootloader to boot all your systems, there will be no menu.lst file but a grub.cfg file which you edit. If you installed Knoppix after Ubuntu and use the Knoppix bootloader with a menu.lst file to boot the different operating systems you need to install Grub2 from Ubuntu to the mbr before you format the Knoppix partition or your systems will be unbootable. So which systems Grub are you using?

Bump. ?

You need to have a bootable windows 7 cd/dvd or usb now before it is too late. Make a backup on windows now. Might as well make a password reset disk too.

Ubuntu was the last OS I installed, so it would be Grub2 from that OS that's running the show. Anyway, I bit the bullet and deleted the Knoppix partition and reinstalled both windows and Ubuntu. Now, for security measures.....

Also, I apologize for the delay in response...been a busy bee
