Dual boot Ubuntus cause out of date grub/menu.lst

Bug #254752 reported by Daryl Lublink on 2008-08-04
This bug affects 1 person
Affects Status Importance Assigned to Milestone
grub (Ubuntu)

Bug Description

1. I installed Ubuntu Hardy 8.04 on sda1 and sda5(swap).
2. I installed Ubuntu Hardy 8.04 on sda6 and sda7(swap).
3. I updated Ubuntu sda1 to Intrepid
4. Grub is now controlled by sda6 and any time Ubuntu Intrepid updates it's kernel, it is no added to grub since grub/menu.lst is on sda6 instead of sda1.

Should ubuntu installer share the grub/menu.lst file?

There is insufficient information in bug #290140 to conclude these are the same bug. un-duping.

This is in fact NOT a duplicate issue. The issue I have raised is when dual booting different versions of ubuntu, each version creates it's own /boot directory + contents, and the MBR usually points to the OS that was installed second. When the first OS has an upgrade, it updates /boot/menu.lst on it's own partition and does not appear in Grub because Grub points to the second partition.

I do not know if this is a bug or wish list, but perhaps when installing a second version of ubuntu on the same machine it should offer to reuse /boot of the first installation ?

I can confirm this still is happening using grub2 in Lucid. If there is one version of Ubuntu on the hard drive, and a new partition is used for the 2nd installation, the grub contents will not update when the earlier installation is upgraded.

Changed in grub (Ubuntu):
status: New → Confirmed
