Installation of Ubuntu 18.04 Bug 13467

Is there a chance there will be an answer to this problem in the near future? At the moment, Ubuntu on my laptop (Acer) is just useless. I thought the computer could not install Ubuntu due to a bug in the BIOS. However, this does not seem to be the case. It seems that the laptop prevents the installation of GRUB in the wrong partition, causing a mess of the system.
It seems that this is a serious mistake that needs urgent attention!
