Does every distro need grub on multiboot system?
I have 5 hard drives and 4 os's (mint, debian, ubuntu, windows 7). Does every distro need grub installed to work properly?

No, you can put one grub in the MBR and use it for all distros and windows 7.
You'll need to run this command from which ever distribution you installed grub from.
It should find the other Os's and you should be set to go.
you may want to consider Refind boot manager found here: http://www.rodsbooks.com/refind/
It will scan all disks then you will be able boot any Os's it finds.
Good Luck.

Code: Select all
sudo update-grub

Re: Does every distro need grub on multiboot system?
If using UEFI machine to multiboot, no distro actually needs Grub installed. As above, use "refind" boot loader and learn how to use "efibootmgr" tool included in most good systems. If you really stuff up, you can go to UEFI "Bios" and set boot order in there to recover.administrollaattori wrote: ⤴Fri Feb 23, 2018 4:06 pmNo. One grub, grub4dos or LILO is enough. With EFI-computers you can use rEFInd also.

Thank you. That's what I did. grub on first disk (sda), and had to specify "ubiquity --no-bootloader" for sdb ,sdc. I ran "sudo update-grub" from sda, and it found everything.
Thank you. sorry, I should have been more specific. no UEFI.greywolf wrote: ⤴Fri Feb 23, 2018 5:38 pmIf using UEFI machine to multiboot, no distro actually needs Grub installed.

Re: Does every distro need grub on multiboot system?
you can also install the grub loader into the /root partition of each installed system,
and then just use the Last Installed System to install to the MBR of SDa - to control the whole machine.
or you can just use the easy way, like I'm inclined to do:
- install each system & let it install grub to the MBR of SDa - on each installation,
so, again, just use the Last Installed System to install to the MBR of SDa - to control the whole machine
works for me.
if you do wish to use the windows system, as well:

will allow multi-control from that Boot Menu, too
this was one way to multi-boot a multi-system:

just providing for several operating systems, was enough for me, though.
