Single Disk Dual Boot Windows 10 on Acer F5

Premise: I tried to read all other posts of people having issues with dual boot and tried all solutions I could find and none worked so far.

System Description: An old Acer F5, one SSD, initially with Windows 10 installed.

What I did: Download Fedora 43 Workstation, burn the USB stick with the image, shrink one of the windows partition to free up space, install Fedora 43 using the available space on the disk.
The installation is successful with no error.

The problem: Windows always starts automatically at every start up, no prompt appears to ask which OS I want to start.

What I tried so far:

  1. Check the windows boot order, Linux doesn’t appear anywhere
  2. load again the Fedora live with the USB stick, run sudo efibootmgr, realize that Fedora is present in the boot list but not in the boot order
  3. run sudo efibootmgr --bootorder XXXX,YYYY... and correct boot order, set Fedora first
    before:

    after:
  4. Restart the system, but windows still starts automatically
  5. Run again Fedora live, run sudo efibootmgr and I see that the boot order is back to what was initially
  6. I also tried to re-install grub via the Fedora live but it also didn’t have success and I also checked if the fedora boot is found in the efi partition and it is found. Sorry for not pasting here the commands run and the result, but I cannot find again the command I used and didn’t take any picture at that time …

Additional info:
during the installation the following partitions were used:

Don’t be surprised if you see ubuntu too in the boot list. After trying everything with Fedora I thought maybe it works with another Linux distribution. So I tried to same with Linux Mint and still had the exact same issue. So now I’m back to Fedora since it’s my preferred choice.

I will really appreciate if someone can help me!

Try going into the BIOS and setting up what to boot in the BIOS.

If I go into the bios at the start up to check the boot order I don’t see the option Fedora…

I wonder if you need to mark the Fedora EFI file as “trusted for execution” as per this Arch wiki guide?
