ext4 on Ubuntu Jaunty x64

Are you wanting to get rid of that Windows partition? If so, then just install Jaunty to it using only a / ext4 partition. If it's just for testing Jaunty out, then there is no need to separate a 30GB partition into various partitions.

I would imagine that Jaunty will recognize Hardy and adjust the /boot/grub/menu.lst file accordingly. However, the MBR will be written to your new partition. If you want to avoid that, then just decline that GRUB be installed during the Jaunty install. Once finished, boot into your Hardy install and edit the menu.lst manually.

 

Hi chronomatic,

The 30 GB part. is not needed (previously used to store Acronis backups from
my Windows XP drive). However, I think I will take Arup's advice as I don't want
to get into a situation where I can't boot XP, and also because I am not a Linux geek
Furthermore I won't be able to mount Hardy(ext3) or I suppose
XP(ntfs) from within an ext4 Jaunty partition.

Regards

 

I will do it as you outlined above. When adding the new menu entry
(title Ubuntu Jaunty
root hd1,4
chainloader +1)
is it necessary to run update-grub command ?
Is there such a thing as chainloader +2..3..4 etc. ?

PS. Have you tried Remastersys Grub Restore ? I have this in my System>
Admin menu.
Apologies for all the questions - maybe there should be a Beginners sub-section
added to the forum ?

 

You shouldn't need the chainloader entry. You would need something like:

Code:

title Ubuntu Jaunty
root hd1,4
kernel /vmlinuz-2.6.28.xxxxxx root=/dev/sda4
initrd /initrd-2.6.28.xxxx.img

Basically what you have plus the kernel and initrd lines. You can find out the proper versions of these by looking inside /boot on your Jaunty install. Also be sure that root=/dev/sda4 is changed to whatever device your Jaunty / partition is on.

No, I haven't. I don't use Ubuntu (Fedora here)

 

That sounds easy enough - and when there is a kernel update for either distro,
the kernel will be updated for the distro I am booted into ?
After editing the menu.lst is it necessary to run 'update-grub' ?

Thanks for your explanation.
Regards.

Edit: I think I would have to manually update the Hardy menu.lst 'stanza' for Jaunty when the Jaunty kernel gets updated.
the chainloader would solve this minor inconvenience ?

 

Ocky,

Now that I think about it, I would just let Jaunty install Grub to the MBR. It should auto-detect Hardy and will probably set both of them up automatically.

 

Forgot to place brackets in previous post .. root (hd1,4)
I have decided to use chainloader - it will be easy for me to remove the
Jaunty stanzas and reformat that partition when the need arises.

So far I am still not sure whether I need to run update-grub from terminal
after adding the Jaunty chainloader stanza to Hardy's menu.lst. ?

Do I place the Jaunty chainloader stanza just above the END DEBIAN AUTOMAGIC KERNELS LIST ?****

Oh yes.. I think the swap partition will be shared between the 2 Ubuntus. ?

**** No, should go below.

 

The new version supports ext4. BTW: SGD is now also included in the Parted Magic ISO but I'm not sure if it's already the newest version.
