install arch in a windows/ubuntu laptop

I have installed arch using:
https://wiki.archlinux.org/index.php/In … tion_image

now I am lost in order to boot arch.

I think I have to install arch-grub in arch partition and then add in ubuntu-grub an entry to jump to arch-grub; or maybe first start arch-grub and then ubuntu grub (i don't mind); but I am lost at how to make this and I don't want to make my computer unbootable.

Any hint is welcome.

There's a "hint" about grub at the bottom of the page you linked to - there are also dedicated wiki pages for both grub and grub2.

Re: install arch in a windows/ubuntu laptop

If you already have Ubuntu installed download and burn RescaTux from http://www.supergrubdisk.org/rescatux/ because even if you get the boot installation wrong in Arch (I certainly have!) it will allow you to boot into Ubuntu. From there you can run (syntax might be slightly wrong here cos its from memory):

sudo install-grub /dev/sda0
sudo update-grub2

It's something similar to the above anyway, and re-installs the Ubuntu Grub2, then updates Grub which will find your Arch installation, and Windows as well. You could use SuperGrub2 disc instead but RescaTux is really good at getting you into your Ubuntu system.

Re: install arch in a windows/ubuntu laptop

I ended with only arch and it wasn't bootable.

I with a liveCD and https://help.ubuntu.com/community/Grub2#ChRoot I recovered ubuntu, and as RichAustin said

sudo install-grub /dev/sda0
sudo update-grub2

worked. Now ubuntu and arch works, thanks.

Re: install arch in a windows/ubuntu laptop

Mmmmm... arch don't work now; I says it cannot find /dev/sda7 (arch partition).

I think I just make "pacman -Syu --force" in arch (--force because if not it was giving errors).

My problem seams related to https://bbs.archlinux.org/viewtopic.php?id=136511 ; I will post later if I managed to make it working.

By the way, ubuntu grub just detects one Arch boot entry. If arch kernel is updated, shouldn't there be more entries? I was hoping that installing ubuntu-grub in MBR and arch-grub in /dev/sda7 whould allow me to have 2 grubs, and when running arch jump from ubuntu-grub to arch-grub. I think I am missing something here.
