[Bug 1995200] [NEW] unable to install GRUB during Ubuntu install

[Íñigo]

Public bug reported:

The PC is a dual system, Ubuntu 22.04 and Win10.
In an Ubuntu update, Ubuntu was damaged, so I did a reinstall.
I chose "something else" during the install, and chose the bootloader to install in sdc4 and root (/) in sdc6, formatting sdc6. This would be to install identically as before.
However, the system was unable to install GRUB in sdc4,stopped the installation and indicated the error.
