Hello, and thanks in advance,


Although I have done some programming (only part-time, long ago, and in obsolete languages)... Currently I'm just a busy user (NOT an IT technician) and don't have the time to fully learn/understand all the concepts in "the GNU GRUB manual".

Anyone generous enough to just answer my question (below), with a bare minimum of assumptions and background explanation? Thank you VERY much. It's GREATLY appreciated.

For many years my single-disk stand-alone Ubuntu 10.4 worked =fine=, after I've tweaked it to identify hard disk drives by device specs (/dev/sda#), instead of by UUID. (Could go into an explanation of why, but it's solid and this email is too long already.)

Now installing latest Mint on a new box, and dusting off my old "disable UUID" configuration notes-to-self.

I am still fine with making all the necessary relevant edits to:
... and then running update-grub2


BUT: I'm rusty, and really need some help on =exactly= what lines to comment out of (or edit within)...
    and (?)
... to identify drives by device specs instead of UUID.

These files are 9.8kB, were created 11 Apr 2014 at 20:51 EST, and came with the Mint 17 install ISO.

My best guesses are, on each of the above two files:

  Comment out the section on GRUB_ENABLE_CRYPTODISK (am not using)

  Comment out:
    the two lines starting with   if fs_uuid=
    their then lines (and the subsequent then code),
    their else lines (but NOT the subsequent code),
    and their fi lines.

Correct guesses?

Notes: Will do this on a "scratch monkey" at first. All data very well backed up, and off-site.

Help.  Thanks!
