Comment 2 for bug 1853717

It is a Toshiba Satellite C850-D - 102

I also got a report of Ubiquity install.py crash

When upgrade from 19.04 failed, at restart I still had access to grub menu and Ubuntu Recovery (message of End Kernel panic). After the fresh reinstall from Live CD failed (I got graphical warning and made this report) I have no more grub :

error : file '/boot/grub/i386-pc/normal.mod' not found
Entering rescue mode...
grub rescue>

There is a windows 7 version installed on the unique SSD (sda), and live CD of Ubuntu 19.10, as well as previously Ubuntu 19.04 in dual boot with W7, worked fine.
