Double boot, keeping 9.10 GRUB

[arashiko28]

Hello, there!
I'm installing 10.4 on a empty partition on my laptop, to test it, since last time it was a major headache. I want to keep the 9.10 GRUB to be the one that controls the boots and leave LL just for testings, is there a way I can do this?

Yes,and it would be a very smart decision. When installing 10.04, at the last installer screen before clicking Install click on Advanced. There you can tell it not to install a bootloader (grub2).

If you have only ubuntu (no current dual boot) don't be surprised that 9.10 will boot directly when you restart. It still doesn't know 10.04 is around. Once 9.10 boots up, just run

sudo update-grub

and it should detect 10.04 and from there on offer you grub boot menu at start to select an OS.

couldn't pass the partition assignment step on the installation. :S:S

Still want to try the upcoming 10.04, but keep having a couple of problems. Here's my partition table, with the unallocated space where i want to install 10.04 but can't pass from partition assignment for installation. :frown:

I also want to keep the 9.10 GRUB to be that that controls the boots, how do I do this? All I remember about GRUB has changed, not even the files are the same anymore.

where is menu.lst???

I have looked back and forth the /boot/grub/ for menu.lst and can't find it!

Unless you upgraded to 9.10 from an earlier Ubuntu distro and kept your previous grub, you will not have legacy grub (0.97) but will have grub2 which does not use menu.lst

As per the above reply, GRUB 2 does not use menu.lst.
Look here for more details:
