Evening all
Well the testing of LMDE went seriously wrong on Sunday.
Having been in the situation where I formatted and partitioned the wrong
drive in the past I made doubly sure that I knew where all the drivers were.
Internal SSD SDA
SDA1 root, SDA2 Home, SDA3 swap
External USB SSD SDB
SDB1 backup
External USB Disk SDC
SDC1 Root, SDC2, Home, SDC3 swap
Memory stick SDD
Single partion from which I was installing LMDE from
So based on the above I was happy I knew where everything was and what
was going where
So the short story being at some stage the USB Memory stick became SDB,
my backup drive became SDC and the external drive became SDD. Now for
the strange part I found LMDE installed on both SDB & SDC (as they
should of been), I only installed LMDE once and I did not remove the
memory stick until I had completed the install. The install wiped and
partitioned of my SDB (which became SDC) drive wiping out over 18months
of backups.
I have got the drives back to where they should be, had to re-install
grub as I unplugged the external SDC drive and wiped SDB of the LMDE
install. I did consider having a play and trying to find out which LMDE
was booting but by that time I was to peeved at losing my backups to care.
Finally when I rebooted after reinstalling grub (via a live distro on a
USB stick) it still had an entry for LMDE on the grub screen so I still
need to resolve that issue.
That will teach me to play around with a system that was working
fine.............

So I turned everything off, unplugged the USB Harddrive, started the
laptop up, came up with the welcome to Grub screen then gave the
option of the disto on the internal hard disk or the distro on the
external, I choose the internal install and it loaded without an issue.
So I have done a little checking, I have looked at /boot/grub/grub.cfg
and there is no "menuentry" for the LINUX MINT DEBIAN EDITION (LMDE),
there are 3 entries for the Linux Mint XFCE edition and it waits about
4 seconds before booting into Linux Mint XFCE. But having said that if
I check /etc/default/grub the GRUB_TIMEOUT=0 which means it is
automatic load, which would be right as previously before installing
LMDE and setting it to install grub on SDA Linux Mint loaded with out
any sign for grub which would be right for GRUB_TIMEOUT=0 from what I
understand.
I did try running grub-emu which is supposed to display the menu list
which said that the file could not be found (bear in mind that dev/sdc
where LMDE was installed, is currently unplugged)
The version of grub installed is 2.06-2ubuntu7.2 which is the same
reported installed in Synaptic (apt gui) on Linux Mint XFCE which is
the installed distro on the laptop ssd, I was testing, Linux Mint
Debian Edition (LMDE) which was installed on the external disk
So it looks like there is some Grub installed else where but is not
stopping me from booting the installed Linux Mint XFCE

Hi Tim,
So how do I confirm if I did install grub onto dev/sda for the
installed day to day distro.
My guess:
- Turn everything off.
- Unplug the external USB drive.
- Turn the PC on.
- Expect GRUB to appear, offering your old installation.
- Select it.
- See if it boots it successfully.
Once I have that information how do I go about updating Grub so I can
remove the distro I was testing and just leave the day to day distro
please.
That may depend on the style of GRUB installation set up by the
distribution. If you have a /boot/grub/grub.cfg then that will have
‘menuentry { ... }’ entries matching what you see.
