Hello,
My system have several partitions :
/dev/sda1 : root partition for a Debian testing 64 bits
/dev/sda2 : /boot partition
/dev/sda3 : root partition for a Debian testing 32 bits
/dev/sda6 : home partition
/dev/sda7 : opt partition
When I run update-grub2 from the 64 bits version, the 32 bits version entries
are not bootable.
They all point to /dev/sda1 partition, while 32 bits root is sda3.
The problem is the same, but inversed, if I run update-grub2 from the 32 bits
version.
Does `sudo linux-boot-prober /dev/sda3' on the 64bit one or `sudo
linux-boot-prober /dev/sda1' on the other one get it right?
It should read the correct value for root= parameter from the grub.cfg
on the device you give it.
On the 64bit :

But /dev/sda3 is the 32bit root.
The results of this command gives root as
UUID=cfe65d23-6e74-407b-af61-a80d40eff118 but it is not correct :

I will try this command on /dev/sda1 at midday.
