Bug Description
I installed many times first ubuntu then win 10 or vice versa.
Ubuntu 16.10 installation hangs when it tries to install grub.
I made the installation following last post in this topic http://
The problem is that you cannot put linux uefi boot manager to take over before windows boot manager.
I can boot linux by pressing F12 which brings up the laptop boot menu , where i am presented by the dialog to choose windows boot manager or linux.
If I don't press F12 computer boots windows 10.
I can see the boot order of EFi with
sudo efibootmgr
and I can see that windows boot manager is before linux.
sudo efibootmgr
BootCurrent: 0000
Timeout: 0 seconds
BootOrder: 0003,0000,
Boot0000* Linux
Boot0001* Unknown Device:
Boot0003* Windows Boot Manager
Boot2001* EFI USB Device
Boot2002* EFI DVD/CDROM
Boot2003* EFI Network
Now, when I try to change the order and put Linux boot loader to be first
with the command
sudo efibootmgr -o 0000,0003,
pc freezes same as it froze during installation when it tried to install grub.
I have also tested with latest efibootmgr on ubuntu 17.04 alpha
with same results.
The funny thing is that this laptop came with linpus pre installed that never booted. I contacted Acer Greece support and they told me to install only Windows 10.I thought I ve seen many things in computers and IT . I would never imagine that a laptop with original OS Linux would have such big problems with linux.
