I share the feeling, Jon. Unfortunately, the only constant in life is
change.
On the bright side, look at what the GRUB2 site says:

For me, at least, "rescue mode" {haven't needed it, but I think it's a
good idea], "boot LiveCD ISO images directly from hard drive" [have
needed it and hated the alternatives], and "non-x86 platform support"
[think about the every growing number of SOCs you want to play with]
make the change palatable.
Of course, these new features probably amount to a big whatever for a
lot of EMC2 users who are in this game to make chips fly and not to keep
learning new software tricks.

Should be a law against it. However, it should be possible to install the old grub over the newfangled thingy, using grub-install [1]. That at least should provide time to become a late adopter. At least in the case of "upstart", it still supports the /etc/rc?.d and /etc/init.d directories. Legacy comaptibility is a boon for legacy skillsets. I'm on your side.

Re: [Emc-users] linux dual boot
9.10 does use grub2, but the correct answer was given by micges. Use Synaptic and search for "linux" in Name only (not Name and Description). Uninstall all but the newest linux-image*** and linux-headers*** packages. You want to leave linux-generic, linux-headers-generic (if it's installed), and linux-image-generic so it will continue to get kernel updates. This will also clear up a lot of disk space.

Thanks everyone - Richard got the right answer - its Grub2. Unfortunately, it seems to be more difficult to set up than the web pages suggest - e.g. Startup Manager which I have just installed, only has half the options the webpage says it should have!!

Re: [Emc-users] linux dual boot
9.10 probably installed Grub2 which has no menu.lst. (I think upgrades to 9.10 retain Grub legacy, new installs use Grub2 - quite different) There is a useful starting point here: https://help.ubuntu.com/community/Grub2 Richard Andrew wrote: > On my ubuntu it's here: > > /boot/grub/menu.lst > > > On Saturday 06 Mar 2010, Ian W.

Re: [Emc-users] linux dual boot
As you upgrade Linux, it installs new (hopefully bugfixed) versions of the kernel. But it doesn't automatically remove the older versions of the kernel, for in case the new version doesn't work. Once you're happy that the new version of the kernel boots & works, you can remove the older versions, and they'll disapear from the grub boot menu. -- Sebastian Kuzminsky never be discouraged just let your nerdy flourish -Original Message- From: "Ian W.
