jean-michel.masereel Ubuntu uses grub2 and Mageia will not recognise it or add it to the menu. I don't know anything about xubuntu or burg. I find it best to use the following syntax when dual booting from legacy to grub2, this way kernel updates in Ubuntu are catered for :- title Ubuntu root (hdx,y) kernel /boot/grub/core.img As far as other "normal" linux distros using legacy there is no problem in beta1 that I have found (my Ubuntu installation uses legacy) menu.lst:- timeout 10 color black/cyan yellow/cyan gfxmenu (hd1,6)/boot/gfxmenu default 0 title linux kernel (hd1,6)/boot/vmlinuz BOOT_IMAGE=linux root=UUID=9d93628f-b81a-4e6d-a436-173697556020 resume=UUID=1097bb8c-3820-4b3a-b796-b417c9aa56d8 splash=silent vga=788 initrd (hd1,6)/boot/initrd.img title linux-nonfb kernel (hd1,6)/boot/vmlinuz BOOT_IMAGE=linux-nonfb root=UUID=9d93628f-b81a-4e6d-a436-173697556020 resume=UUID=1097bb8c-3820-4b3a-b796-b417c9aa56d8 initrd (hd1,6)/boot/initrd.img title failsafe kernel (hd1,6)/boot/vmlinuz BOOT_IMAGE=failsafe root=UUID=9d93628f-b81a-4e6d-a436-173697556020 failsafe initrd (hd1,6)/boot/initrd.img title Linux sda1 root (hd0,0) configfile /boot/grub/menu.lst title Mandriva Linux (Official) root (hd0,17) configfile /boot/grub/menu.lst title alt_Mandriva Linux (Official) root (hd0,15) configfile /boot/grub/menu.lst title Ubuntu 10.04.1 LTS root (hd0,11) configfile /boot/grub/menu.lst title Mandriva Linux (Cooker) root (hd0,21) configfile /boot/grub/menu.lst title PCLinuxOS (PCLinuxOS) root (hd0,20) configfile /boot/grub/menu.lst title alt2_Mandriva Linux (Official) root (hd0,9) configfile /boot/grub/menu.lst title alt3_Mandriva Linux (Official) root (hd0,4) configfile /boot/grub/menu.lst title alt_PCLinuxOS (PCLinuxOS) root (hd0,13) configfile /boot/grub/menu.lst title alt_Mandriva Linux (Cooker) root (hd0,12) configfile /boot/grub/menu.lst title Mageia (Cauldron) root (hd1,4) configfile /boot/grub/menu.lst CC:

zen25000 (In reply to comment #1) > Ubuntu uses grub2 and Mageia will not recognise it or add it to the menu. I thought that after an install the boot loader (or distrib?) detects the other distribs by another method than just read a menu.lst file!!? (for example by detecting vmlinuz or initrd files) What if I want to use lilo for example? Furthermore, I thought that grub tends to desapear for grub2 ??? I will try to install a mandriva in my virtual machine (of course after changing grub of mageia by grub2 of xubuntu) and see what hapens... ;-) (In reply to comment #2) >> Ubuntu uses grub2 and Mageia will not recognise it or add it to the menu. > > I thought that after an install the boot loader (or distrib?) detects the other > distribs by another method than just read a menu.lst file!!?

Yes I am sure you are correct, but in the case of grub it does not look for grub.cfg AFAIK so ignores grub2 installations. This has always been my experience in Mandriva and the (best IMHO) workaround is in my previous reply. > Furthermore, I thought that grub tends to desapear for grub2 ??? If you mean it will be replaced by grub2 then no, not in the immediate future at least. > I will try to install a mandriva in my virtual machine (of course after > changing grub of mageia by grub2 of xubuntu) and see what hapens... ;-) Not sure I understand exactly what you are going to do with grub2 and Mageia, but OK. ;-) First I want to explain that I've always used redhat/mandrake/mandriva distribs until 2 months ago when I wanted to test ubuntu... That's certainly the reason why I never experienced such problems :-) (In reply to comment #3) > (In reply to comment #2) > >> Ubuntu uses grub2 and Mageia will not recognise it or add it to the menu. > > > > I thought that after an install the boot loader (or distrib?) detects the other > > distribs by another method than just read a menu.lst file!!?

Ok, but since there is some ascending compatibility problems between grub and grub2, isn't it possible to be able to choose between both in the installation procedure?? > > > I will try to install a mandriva in my virtual machine (of course after > > changing grub of mageia by grub2 of xubuntu) and see what hapens... ;-) > > Not sure I understand exactly what you are going to do with grub2 and Mageia, > but OK. ;-) - I installed mageia beta1 : OK - I installed xubuntu : OK (it detects mageia and add it to grub2 menu) - I installed mandriva 2010 RC1 : NOt OK! : it only detects mageia (which is a good thing) but not ubuntu (certainly for the reason you explained previously) The worst thing is that mandriva destroyed my partition table and I couldn't add ubuntu in the menu.lst (it is in a partition that is detected on mandriva but not at boot time, and not on mageia!) I couldn't fix the problem, even with testdisk and the 3 installation DVDs, and it seems that the partition is lost. By luck, it was on a "testing virtual machine" !! ;-) So in conclusion, what I called a "bug" is not a bug of mageia, it's only a problem between grub and grub2, and was already present with mandriva2010. Thanks for your help. Continu your good, it will certainly make me comme back to the mandriva world and leave ubuntu :-D >Ok, but since there is some ascending compatibility problems between grub and >grub2, isn't it possible to be able to choose between both in the installation >procedure?? Not yet, although I think that may come in time. It is possible to install grub2 in Mageia (I am currently testing it) but a lot of work would be needed before this could be offered during installation. The goal of Mageia 1 is not to make any major changes! >it will certainly make me comme back >to the mandriva world ...and Mageia I hope! ;-) @Ahmad - please mark as invalid/closed CC:
