I installed the ubuntu 17.04 and windows 10 in the same hard disk with uefi enabled laptop, to start ubuntu i should go the bios and change the boot order every time, which is deffecult work.
Is there any way to start the ubuntu from windows 10, i read a post there was a dos command run execute the efi file from the efi partiton and start the ubuntu from windows dos, but i lost that post and didn't find it again. the EasyBCD is not working in the uefi secure enabled.

shams,

I can only refer you to these two comprehensive dual-booting guides:

Personally I would not touch EasyBCD.

Good luck! I have never managed.

The solution that I found:

1) go to store, buy Windows 8 for 32
2) partition with gparted live
3) install win 8
4) install Linux
...
Working

(after later override with freebsd)

Probably simply a default issue. I also haven't bothered to test EasyBCD with UEFI.
From Ubuntu terminal, run "efibootmgr" and post the output - this will show the EFI registered boot entries. Should be simple enough to get grub to show a dual-boot list.
When you boot Ubuntu, do you see Win10 listed as an option ?.

You can change the EFI boot order with the efibootmgr command with the -o option so posting the output of efibootmgr would be the first step necessary to get help.

Your output shows an EFI entry for ubuntu as well as showing that entry as first in boot order so there is some other problem. You mention EasyBCD in your initial post, did you install that on windows and try to use it? I don't think it works well with EFI. When you boot the computer and do not intervene in the boot process, what happens? Boot to windows?

Might be best to get more details. Boot Ubuntu and go to the site below and download and run boot repair, make sure you select the option to Create BootInfo Summary and do NOT try to make any repairs. Post the link you are given here and some one should be able to help.

It's interesting that you have an entry for Windows Boot Manager but it is not in the boot order. Who is the manufacturer of this computer?

If you mess with UEFI and not, cannot you damage the data on the harddisk?

I'm not sure what you mean by that statement, particularly the "and not" part. EFI commands modify files on the efi partition so using the commands without knowing what they do can cause damage. The most common problem is users trying to install and make changes and not understanding what they are doing thus corrupting the system. Using EFI is no more likely to cause damage to data on a disk than older MBR boot type commands. Of course, their is no limit to the ways users can mess things up.

You could try turning secure boot off.

I've been wrestling with the same issue, and have shelved trying to do a dual-boot. I'm not sure at this point that Linux Mint (or any distribution) is even compatible with The Dell Inspiron desktop I just purchased. I tried wiping Windows 10 off the thing and just installing Mint standalone as I always used to out of frustration with the dual boot attempt. The machine wouldn't make it through the install, asked for my username and password before the install fully completed. It then refused all typed inputs. Tried to start over and reinstall again, was warned with a banner on the screen that if I persisted, I would never be able to install another bios based system ever again, implying that the UEFI system would be overwritten or corrupted in some sense. I'm amazed at how convoluted all of this has become.

I had to get out the Windows rescue stick I had had just produced a couple of days earlier to get the system back. The whole thing leaves a bad taste in the mouth.

I've read that the newer versions of the major distributions are UEFI compliant. Maybe they are, but I haven't a clue how to make them work with this hardware.

The impression I got, which may be wrong, Is that this goofy UEFI stuff DEMANDS a Microsoft product be the primary OS, will 'tolerate' an old fashioned BIOS based second OS but not by itself, but as a dual boot it can be made to work only if you are a BCDedit expert, which almost no one is because Microsoft barely releases any documentation.

mlytle,

Either follow the advice in post #2 for a dual-boot, or alternatively, go into Setup (keep pressing F2 immediately after switching on) and change from UEFI to Legacy BIOS (or CSM).

You may or may not need to disable Fast Boot or Secure Boot.

It is probably a good idea to boot from a gparted disk and to format the partitions in advance.

http://gparted.org/livecd.php

Example

sda1 ............... root.. (/)...........30GB ....format as ext4
sda2................ swap.................2GB......do not format
sda3.................home (/home).........remainder of drive ....format as ext4

Beachboy2 Thanks for these tips, somehow I missed reading your earlier post. Looking over those two links, I see I was not checking to see if I had booted the Linux in UEFI mode, and was unfamiliar with the Gparted feature. I did manage to disable both Fast Boot and Secure Boot, got that right.

Do you have any opinion as to whether straight Ubuntu or Mint as a Ubuntu derivative is a better choice? Dell, from whom I bought this new desktop, seems to prefer straight Ubuntu, and I was wondering if the Grub2 implementation was better on that version. I've been reading a lot of this stuff over the last few days, I found some interesting explanations over on the site by the guy that has authored the Refind bootloader, but I'm hoping not to have to go that deep, but I suppose I will if I have to.

Some sites are telling people to format their USB sticks with the Win32 Disk Imager as it natively installs the stick as a FAT32 device, I get that from here:https://www.lifewire.com/create-uefi...nt-usb-2202084

I just used my old Mint distribution and it's native utility to create the bootable Mint stick that I used, but maybe doing that from the Linux side rather from the Windows side made a difference or caused a problem, I'm not sure.

It is all down to personal preference.

My preference is to use Linux Mint 18.2 MATE 64 bit, but Ubuntu 16.04.2 MATE 64 bit will work just as well.
