It'll be: /boot/grub/menu.lst

you have looked in the right place for menu.lst, there are still a few options that i know of:

- you possibly have a newer version of grub and that one works different, i have modified mine once and successfully so assuming you make back ups of the files you will modify (as a root) go to /boot/grub/grub.cfg
now i am not a command line specialist but i think, assuming you are running gnome, this is a way to edit with root privileges:

sudo gedit /boot/grub/grub.cfg

you will be prompted for your password. if you are running kde then replace 'gedit' with 'kate'.

i copied a stanza from the bottom to the top so it would appear on top of the list when my system boots, and it works. here's a copy of the stanza for your perusal, the line up the top is like a reference where in the file i did this:

Quote:
### BEGIN /etc/grub.d/10_linux ###
menuentry "Ubuntu 9.04, kernel 2.6.28-18-generic (on /dev/sda6)" {
insmod ext2
set root=(hd0,6)
search --no-floppy --fs-uuid --set 16bbaa72-376b-43aa-bf84-029d7f5548b2
linux /boot/vmlinuz-2.6.28-18-generic root=UUID=16bbaa72-376b-43aa-bf84-029d7f5548b2 ro quiet splash
initrd /boot/initrd.img-2.6.28-18-generic
}

that is one way i know, the other way i stumbled across after i did this but it looked promising, you need to install a program named 'startupmanager', it is a gui based solution. you should be able to install that when using your grub superdisk to get into your system.

I found the thread i mentioned much earlier in this thread about my problem with clones, it is worth a read, it also addresses the problem with UUID's

well i had a quick look at the site but that doesn't look anywhere near the startupmanager i was referring to. the one i mean can be found in your package manager (in the repositories and assuming you have enabled all the repositories in your package manager, possibly called synaptic but not sure, were you using Mint?) it is in the 'universe' repositories.

and yes that is a linux version, ubuntu linux in this case.

...to clarify for me: Aren't the first 446 bytes the MBR and the next 68 bytes the partition table; or is the entire 512 bytes (including the partition table) considered the MBR?

Edit: Just realized the question I asked was about a post quite a ways back in this thread. Didn't mean to confuse or sidetrack anyone, but still curious.

Master Boot record = 512 bytes
448 bytes contain the primary boot code (stage1 boot loader)
The remaining 64 bytes contain partition table.

hope i am correct.
