Public bug reported:
I'm trying to install Ubuntu as dualboot to Windows 10. But every time,
grub fails to install. At the end of the installation, there's the error
"Grub installation failed. This is a fatal error. " I tried the
following things:
secure boot is disabled
fast boot ist disabled
win is installed in EFI mode so of course I'm installing Ubuntu in
EFi mode too
Some more infos: It's a 64 Bit acer Laptop with UEFI, with an AMD Radeon
E2-9000e and a Radeon R2 graphic card and 4GB RAM DDR4 if that matters.
During the installation, I select something else, create a 245.7GB /
partition, a 4.2GB swap partition and around 200MB for EFI boot. After
the first time, the installation always says that ubuntu is already
installed, I guess that means only the grub installation failed, but
Ubuntu was installed. I googled a bit, but did not find anything that
worked.
By the way, the installation USB is probably not a problem, just tested
it on another PC and it worked instantly. I also tried both the "install
Ubuntu" option and the "try Ubuntu" and then installing it.
Does anyone know how to fix this?
