I need to reset my password. I have followed these steps:

How do I reset a lost Administrative(root) password?

However, then I go to "root" or "netroot" recovery options, it tells me:

Give root password for maintenance (or type Control-D to continue)

Clearly, I do not know the root password. If I type Control-D, I return to the list of options. From this page I read:

Under chapter 'The Other Way':

4. Highlight the line that begins kernel and press 'e' to edit

But in the grub configuration file I have no line that starts with 'kernel'. Only:

setparams 'Ubuntu...'
recordfail
set gxfpayload...
insmod part_msdos
insmod ext2
set root=...
search --no-floppy...
linux /boot/vmlinuz-2.6.38...
initrd /boot/initrd.img-2.6....

Those are all lines in my grub. Which line should I edit? Or is there another way to reset my password?
