The third and fourth are more practical tutorial on installation, but you've already got a working system, albeit one that's not working in quite the way you want. If you have time for just one, I'd go with the first, or possibly the second.

The Ubuntu community wiki entry on UEFI - This page is a bit disjointed, but is the most Ubuntu-specific introduction to EFI and its issues.

My page on installing Linux on EFI systems - This page is a more practical introduction to EFI-mode booting than Adam Williamson's blog.

A question and answers on the differences between BIOS and EFI booting on - This provides the basics of the preceding, but is more concise.

Adam Williamson's blog entry on how EFI works - This page describes the theory behind EFI-mode booting.

I suspect you're laboring under incorrect BIOS-mode mental models, which is leading you astray. You should first be aware that modern EFI-based computers boot in entirely different ways from older BIOS-based computers. I don't think my UEFI is buggy, it's quite advanced and more secure than other vendors

This probably implies it would be impossible for any app to modify UEFI settings when Secure Boot is disabled.

GRUB2 WINDOWS 10 BCD PASSWORD

I have to enter that password everytime I goto UEFI menu. Secure Boot toggle is ungreyed after setting Supervisor password in UEFI.

GRUB2 WINDOWS 10 BCD UPDATE

Update 4: I configured boot order from Windows bcdedit and now the boot order persists across boots. Update 3: I rebooted to Windows and it deleted GRUB boot entry and made itself default again.

How do I add Grub/Ubuntu bootloader entry to Windows Boot Manager? Does Windows Boot Manager support such configuration? I am in doubt now because when Windows Boot Manager was default, it deleted GRUB boot entry in EFI at every boot.ДЄnother thing worth noting, I did not disable fast startup in Windows probably because of it Ubuntu installer could not install GRUB (or it installed grub but Windows Boot Manager that loaded first because of fast startup, removed it at boot) I am now using GRUB (via shim with SecureBoot Enabled) as the default bootloader. Update 2: I followed 's blog and fixed grub not being shown in UEFI boot menu using efibootmgr. It came with UEFI firmware ('BIOS Version' in System Information) V1.1. System Information shows- BIOS Version : Insyde Corp V1.35, 30-11-2015 I have tried reinstalling without a /boot partition but still no luck.Д®dit: It's Acer V3-574G-54VY running on i5-5200U. If grub is present in /boot or /EFI/Ubuntu it should show up in boot menu. Update 1: UEFI boot menu (from F12 key) shows only one entry which is for Windows.

The GRUB screen is quite scary for my siblings who also use my laptop.

GRUB2 WINDOWS 10 BCD UPGRADE

I plan to upgrade to 18.04 LTS and/or update OS shipped kernel to mainline kernel.

I want to keep both Windows boot manager and GRUB but on separate partitions so that I can goto GRUB from Windows boot manager as I did in my old laptop. I can see option for adding a boot entry for another Windows OS but the same options are greyed out for linux OSes. EasyBCD say that because I have secure boot enabled some features are not supported. I rebooted into Windows and ran EasyBCD 2.3 (latest) to add a boot entry for grub in windows boot manager.Д«ut that option was greyed out. I thought this will install grub on /boot (It might have, I don't know) I installed Ubuntu Gnome 17.04 with the following partitioning- /boot ext4 1GB My new laptop came with Windows 10 pre-installed with UEFI. This enabled me to keep windows boot manager as well as grub. My old laptop used MBR scheme and I was able to install grub on Ubuntu's partition (not on MBR) and then added a boot entry for grub in Windows boot manager. If UEFI is enabled, only TRUSTED boot managers are loaded by UEFI and all others are ignored because of which only windows boots and we incorrectly think UEFI forgets boot entries.ДЄn alternative is to disable UEFI but why lower the security ourselves when there is a solution? The long story You can disable secure boot too if a password is set. You can then mark any third party boot manager as TRUSTED without signing the boot manager with RSA key (as shown in the gist and many other places). Installation steps are well explained in this gistД«ut Acer laptops (tested on 3 Acers) apparently forgets boot entries and only windows boot manager loads despite refind/grub is present in ESP.ДЄcer laptop's UEFI menu has two hidden settings that become available only when you set a password for the UEFI menu. It's not possible to add Grub boot entry in Windows Boot Manager.Д«ut something similar can be achieved using a third party boot manager like Rod Smith's rEFInd.
