[Bug 1813190] [NEW] ubuntu installation from usb crashes

[Hèctor Alòs i Font]

Public bug reported:

I understand very little about all this, so I can't help much. I'm
trying to install Ubuntu alongside with Windows. I reserved 50 GB from
the disk (seemingly there is just one physical disk) and I tried to
install Ubuntu from a USB. Everything goes fine until, as far as I
understand, the installer tries to install the grub-installer programme.
At this point the installer crashes. I've tried a second time, and I've
got the same error.
