Boot issue after installation on Acer Swift 3 laptop (only with 64 bits version)

Hello all,

I bought an Acer Swift 3 recently and I tried to install Linux Mint 18.1 on it. I had boot issue after installation even if the UEFI and secure boot were activated or deactivated. It is very strange because I tried with both Mint 18.1 Cinnamon ‘’64bits’’ and Ubuntu 16.04.1 ‘’64bits’’ and I had the same issue. When the istallation finishes, it asks me to reboot and then it asks me to remove the USB drive and press enter. After I press enter, it the laptop restarts and I have a message that the are no bootable devices to be found. When I look in the laptop’s BIOS, I see that My SSD drive (liteon 256GB) is in the first position to boot. Even if I press F12 to get the Acer boot menu at start up, I see the SSD drive but when I select it I still get the error message. I booted back with the USB drive in a live session and started gparted. I see that there is a small EFI partition in fat32 and then the ext4 and swap partition.also i saw acer brand explainer video . What is strange about this laptop’s UEFI/BIOS is that I can’t deactivate secure boot alone and keep EUFI boot. The only way to deactivate secure boot is by deactivating the UEFI boot and go to legacy boot. So I tried installing the 64 bits versions of both Mint 18.1 and Ubuntu 16.04.1 in Lecacy boot but I had the same issue and there is a EFI partition created even if I istalled it on Legacy boot. I also tried to manually partitioned the drive in the installation process without the EFI partition like I was used to do with my old laptop. The problem is that the installer doesn’t let me do it and I have the message that I need to have the EFI partition (I can’t go fruther in the installation process after I get this message). In legacy mode I should be able to do only an EXT4 partiton and a swap? So I tried with 32 bits version of Mint 18.1 and everything worked fine. I only see my EXT4 and Swap partition in gparted and it boots up realy fast. The only problem is about the fact that using a 32 bits Linux on a brand new laptop isn’t realy interesting. Do someone knows what can be causing this issue. I’ve installed Linux Mint and other Linux distros on multiple laptops over the years and I never had to face this kind of issue.
