Re: [SOLVED] Trouble with GRUB re-installation - antenor - 11-20-2015
Hello Wirezfree,
please let me speak by what I gained from this recent experience I had which by gold_finger 's guidance had a happy ending!
Install Mint 's GRUB on its / partition and Lite 's one on the MBR. This way you are going to avoid GRUB conflicts.
And yes, it is always good to have swap memory partition, your friend might won't need it but it is better to have it than miss
it, since he doesn't have a problem with his drive 's space.
But no, you won't have to create two separate swap partitions, one will work for both Linux OS.

@antenor,
If I read gold_finger correctly boot loader should be disk#1 mbr, and not / of OS otherwise I would need to use EasyBCD.

@Wirezfree,
antenor is correct on both counts: only one Swap needed and will be used by both Mint and LL; and install Mint's grub to its Root partition and LL's grub to MBR of whatever drive is set to boot the computer (I'm assuming that will be /dev/sda).
If friend doesn't use hibernation, then you could get away with no Swap, but might not be bad idea to have a small 1-2GB Swap just in case it's ever needed. For hibernation make one Swap slightly larger than 16GB.
If installing Mint first, you can install grub to MBR so that you're able to boot into new install and check it before installing LL. But be sure to then install LL's grub to MBR (overwriting Mint's) afterwards to make sure LL is in charge of booting. If you install Mint after LL, then make sure you direct boot loader to its root partition. Then log into LL and update grub to add Mint to boot menu:
Code:
sudo update-grubLL's grub code was altered a bit to make dual boots with Windows easier, (I think), but causes errors and won't boot LL when trying to multi-boot with other Linux distros if their grub is in charge of booting. So, when multi-booting with other distros always make sure LL's grub is the one installed to the MBR and controlling the boot process to avoid having to manually edit grub files to boot LL.
Just to clear up any remaining confusion, if no grub is put on the MBR that would mean Windows boot loader remains in charge of booting. In that case, Windows would not "see" the Linux distro(s) installed and you wouldn't be able to boot into them. That's when you would need a tool like EasyBCD installed on Windows. Grub on the MBR will recognize Windows and boot it, but Windows boot loader won't do that with Linux.

Hello Wirezfree,
I am sorry for not telling you the whole story but I guessed you would catch the clue
by reading what gold_finger answered me.
Given there is Windows 7 installed on the machine, you install Lite beside it, putting
GRUB on MBR, so you will have a dual boot install with Lite first on the booting list as
I already wrote you before and Windows second.
Afterwards you install Mint putting its GRUB on its / and NOT on MBR. You open up your
terminal giving the command sudo update-grub
and that 's it. You got the triple booting machine you wanted.

Thanks both for the clarifications and further details, much appreciated.
Now I need to get on and do it... I will post back

I use this same method and it works ! After installing another OS, boot to LinuxLite and- sudo update-grub
Just remember if you want to triple boot, quad boot, etc.-> to always install grub to the root ( / ) of the drive you installed to. (linux)
I am booting 7 OS's using this method and multiple Hdd's.
I have multiple hdd's with win7,xp, 8 and linux (several versions) and use LinuxLite grub as the main bootloader.
If you break the boot, there is a guide here to get it setup again.
* side note- you must have windows installed FIRST to any HDD in order to have no issues. It's A nightmare if you reverse the order.

Hello Wirezfree,
I am sorry for once again for not having given you all the details. I wrote you that after Mint 's
installation and having put its GRUB on its / you open up a terminal.
technomancer is absolutely right on what he pointed out, you have to restart your machine and
after booting in LITE - not any other OS - you open up a terminal and update its GRUB so it covers
the freshly installed Mint as well.
However, what technomancer and me are doing here is giving you just a practical way for the
triple booting system you want. It is actually gold_finger 's answers you have to study to really
benefit yourself by his knowledge, because HE IS THE MAN!!!

@technomancer
Thanks again for the further details, very much appreciated.
@antenor,
No problems, small and subtle choices can make all the difference
Re: [SOLVED] Trouble with GRUB re-installation - antenor - 11-20-2015
So go for it man,
you have all the tools, if a newbie like me did it you surely can too!
Re: [SOLVED] Trouble with GRUB re-installation - technomancer - 11-21-2015
Not a problem. 8)
If you need any help multibooting let me know. Legacy though ! LOL
-As for UEFI, antenor covered that. gold_finger is definitely the person to ask about UEFI, or just follow his guides.
