Updates change bootloader

Today updates (around 250) changed my bootloader. Before I had 4 operating system, now OpenMandriva Lx 4 only.
Anyone had same problem?
More info on bug 2450.

run
sudo update-grub2
reboot

Thanks for suggestion that I already done but I’d like to know if I’m alone with this kind of bug.

Today it happened again after updating kernel. This is an old bug that sometime come back then I don’t think is related to this problem.

Anyway I’ll delay next updates.
