Dual boot ubuntu 16.04 and win10 on friend's laptop

[Edwan Kael]

Hey guys, I've been looking everywhere for solution, this is actually for my friend's computer, not mine.
My current machine:
1. "Nettop" from 2009: running xubuntu 16.04, atom 330, 2GB DDR2, 500GB HDD.
2. Acer E5-574G: dual boot xubuntu 16.04 and win10, 6200u, 12GB ram, 240GB SSD.

1st one is of course not using an uefi bios, so install is really simple, just install and good to go
2nd one is using uefi, but still not hard at all, just put grubx64.efi as trusted in uefi menu

**Actual question start here:**
My friend's laptop (Acer Z1402-31ZJ)- i3-5005U,4GB RAM,1TB HDD
After installing Ubuntu 16.04, it boot directly to windows 10. I know that's normal, so I tell him to add grubx64.efi as trusted.
But this is the laptop eufi menu. I have no clue. Seriously. Thanks for the help in advance. Pictures are attached below.

The Ubuntu installation should've installed grub, I don't understand why it doesn't boot with grub and goes directly into Windows 10..

His laptop only have secure boot key management when secure boot was set to custom.

Sometimes windows over writes the boot because it assumes its the only operating system.

Anyway to prevent it from getting overwritten? The bios doesn't have many option, not even set supervisor password.

nope. You just have to reinstall grub again.

If the OS selection was not in UEFI mode when you installed the OS ubuntu may have automatically installed in BIOS mode... so after the install, when you changed it to UEFI it clearly won't appear.

 

I recommend you reinstall ubuntu, with the UEFI config as it is right now, or use a live CD to chroot into the installation and reinstall grub, but first option is just easier and quicker.

 

All this if you haven't been able to get it running still, sorry i took so long to respond I was away on holiday.

Ubuntu boots in UEFI mode, I'm 100% positive.

It's just that in order to boot into it, you have to set ubuntu to one time mode in EasyUEFI in order to make it the first in boot priority.

However, the next time it boots, it boot into windows again. There's isn't a way to make it permanent AFAIK.
