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.
