I'm using an ACER Predator G3-710 and just installed my Ubuntu alongside Windows 10 on a second SSD-Card that was previously empty. Everything went fine but after restarting my PC it always boots into windows immediately and won't show the Grub menu. I also can't find Ubuntu in my BIOS Boot settings.

Solved: I had to disable save boot in my BIOS settings and change the bootpath using this article.

By running this in my terminal

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Thanks for all the help! :)

  • What Ubuntu release are you using? Can you see "ubuntu" in the EFI menu (some key at power-up to allow selection of boot device or OS)? Did you try putting an EFI partition on the SSD-Card to allow booting that device (see bug https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396379 for your selection of bootloader location gets ignored). – ubfan1 Jan 15 '22 at 17:19

    Do you have an "unknown" UEFI setting? That is the "ubuntu' entry and you have to enable it in UEFI settings by setting trust on it. Acer Trust Settings - details, some now report that then secure boot has to be on to set trust: https://ubuntuforums.org/showthread.php?t=2297947&p=13369742#post13369742 Another Acer should be similar: https://ubuntuforums.org/showthread.php?t=2437702 & https://askubuntu.com/questions/1194761/how-to-install-nvidia-geforce-gtx-1050-ti-drivers-for-ubuntu-18-04-03-lts-on-ace – oldfred Jan 16 '22 at 01:35
  • @ubfan1 I can't find Ubuntu in the EFI menu. I believe I tried putting an EFI partition on the SSD-Card but I'll look over it again. TY – RFö Jan 16 '22 at 18:29
  • @oldfred Somehow I can't find "Select an UEFI file as trusted for executing:" in my BIOS – RFö Jan 16 '22 at 18:29
  • Many newer Acer require Control S and/or Secure Boot on to see additional settings. – oldfred Jan 17 '22 at 00:23
  • @oldfred I have Secure Boot on in my BIOS but what exactly do you mean with Control S? Sry I'm a complete noob. TY :) – RFö Jan 17 '22 at 16:29
  • See answer by this user who mentions it for ACHI settings. https://askubuntu.com/questions/1217061/installation-on-acer-swift-5-freezes-no-partitions-shown and this one: https://askubuntu.com/questions/1211911/cannot-install-ubuntu-on-acer-aspire-a515-54g-laptop-hard-drive-not-detected control + S – oldfred Jan 17 '22 at 21:51
  • @oldfred Control + S doesn't work on my Acer. I read that this is only possible on some of their laptops. – RFö Jan 18 '22 at 18:11
  • Do you have the latest UEFI from Acer. Many have had to update that, particularly older systems. Some had posted they had to downgrade UEFI, but then newer posts say upgrade did work. Acer Very latest UEFI/BIOS works, downgrade not required if no trust screens, you must now upgrade: http://ubuntuforums.org/showthread.php?t=2298380&p=13419141#post13419141 – oldfred Jan 18 '22 at 20:20
  • @oldfred It said "R02 BIOS only compatible with Intel 7th Gen Kabylake platform. Not upgrade from R01." in the description. Should I try an older version of R01 then? – RFö Jan 19 '22 at 21:44
