ubuntu 22.04.3 failed ton install Grub on any drive

[Chris]

I was reinstalling Ubuntu, the installer did fine (I chose "install ubuntu 22.04.3 aside 22.04.2"), but the installer could not set up Grub on ant drive.

My startup drive (128 Go SSD) is mounted as sdb, my data drive (320 Go HDDD) is mounted as sda.

I'm gonna try again and if it fails, erase the SSD.
