Linux Mint 18

I have just loaded Linux Mint 18 on an Acer all in on computer and it will not boot.  I have the BIOS set to UEFI on the boot and the security turned off.  When I try to reboot the computer I get the message - Start PXE over IPv4 - and it hangs for several minutes.  After a timeout it asks to have boot media put into the computer and the return key pressed.

It seems the install did no go well, pxe often is the last boot resource, trying to boot of the network.
Double check the boot uefi, to make sure it points to the drive and partition where you installed..
One option, change the boot to bios from uefi and see if it solves ......
Did you also install the OS via UEFI boot?

arnold - I have installed it twice and prior to installing Mint 18, I tried it with Mint 17 and Mint 17.1 with the same results.  I'm not familiar with how to check to see that the uefi is pointing to the right boot device.
rindi - I did a default install from the Linux Mint 18 DVD and had anything that was set to Legacy set to UEFI in the bios.  Hope that helps.
If you install while booting using BIOS, legacy and then changed to UEFi in reboot that is as ri di pointed out the issue. Uefi has no reference to where to boot which is why it falls through to Pxe boot which is the last resort when no......
Prior to booting from the install DVD I checked the bios and all settings were set to UEFI.  I then booted from the DVD, clicked the install icon on the desktop and installed the OS on the hard drive.  At the end of the install I clicked to reboot the system.  In a few seconds a message came up to remove the DVD and press a key.  I did that and after about 30 seconds the error message appeared.  Is that not proper? - Thanks.
Instead of installing from the DVD boot directly, you entered the liveCD, and then ran the  install.
If not mistaken, during the DVD bootup you have a direct install .

Or one of the options to update the disk boot, does not seem to have taken effect,or the uefi boot reference is not there for the new deployed OS.
Can you show how the disk is partitioned? is the partition table GPT? You did use the 64bit version of Mint?
rindi - I did use the 64 bit version and I will check the partition table and report back to you.
You have to turn off "secureboot" in the bios.
If that doesn't help try below.

After the install, when it tries to boot, hold the SHIFT key to force the boot menu to load...

Scroll to the boot option and press "E" to edit the line

Scroll down to the line containing "quiet splash" and replace that with "nomodeset" (don't add the quotes)

Press CTRL+X or F10 to boot
scott_silva - The SHIFT key does not put me into the boot menu.  On the Acer all in one if I use F12 it gives me a box with the heading "Please Select Boot Device."  In the box there is a selection box but the only selection available is "UEFI: IPv4 Realtek PCIe GBE Family Controler."  The next line says "Enter to select boot device" and the next line says "ESC to select default device."  Does that tell you anything?  Thanks scott_silva.
If I put the Mint 18 DVD in it shows up in the list of boot devices but the IPv4 Realtek and DVD are the only two that show up.  When I open the DVD door and look at it again the Realtek is the only one that shows up.
Oh, by the way scott-silva I have had the secureboot turned off during all of  this.
It means that you don't have any EFI boot media in the system. Can you post the partitioning of the disk?
Let me look
OK here is a screen shot.

That looks OK. I have just downloaded mint 18 and installed on a Hyper-V server in EFI mode and get the same partitioning. It boots without problems. Have you tried doing the installation again?
I have done it a couple of times.  I tried it on a HP all in one computer and it installed fine.  When you installed it on your computer, how did you set it up to install in t he EFI mode.  Is that done by setting the BIOS to UEFI rather than Legacy and turn off the secure boot?
Yes, the BIOS needs to be UEFI. Whether Secure boot needs to be off or can also be on I don't know. I have always had it off, but as far as I know Mint uses an officially signed kernel so it should also work with secureboot on.

I am also right now testing it on an ESXi server. There I originally had the same issue. Everything seemed to work, but the reboot didn't find the installation. I then first installed Xubuntu in efi mode, which worked, then booted again to the mint XFCE iso and installed it again to the disk that was setup by Xubuntu, and after that it worked.
Wow, lot of stuff.  I will be interested in hearing what you find out on the ESXi server.  I loaded Suse Leap 42.1 on the same all in one I have been trying to get Mint 18 on and it will load and boot but only if I use Legacy and the boot up screen is goofy.  It does boot however.  I think there is something going on in the BIOS of the Acer all-in-on.  The model number is ZC-700G.
It works fine on ESXi. Maybe you should first just try installing another distro, like Xubuntu, and the n Mint on top of that.
I'll give it a whirl and let you know.
Another thing you can check during the installation. Where you assign partitions at the bottom of the display there is also an option to to select where Grub should be installed.Select the small EFI partition there (usually /sda1).

You have an Acer All-in-One, but which one? I can't find a model identifier in the thread. Also, what BIOS version do you have?
tliotta - the model is ZC-700G.  The BIOS is R01-A4 and at the bottom of the BIOS screen it has a copyright notice for Acer, Inc so I am assuming the BIO is that of Acer, Inc.  Hope this helps.  Thanks
Sheesh... now I see the model just a couple comments back up. Sorry for being blind.

It's a relatively new model, and the 700G probably should have had Win10/Win8 pre-installed and it apparently would have been installed under UEFI rather than BIOS. AFAIK, that means that Linux also must now be installed under UEFI. (UEFI is technically a replacement for BIOS.)

Part 1:


I'd go through all related settings and attempt to get everything away from any "Legacy" values. If you have indeed done that, look one more time for luck. I'd save whatever changes that make the device appear to be completely at UEFI, power down for at least 30 seconds and then start fresh with an install. (Getting all capacitances discharged, etc., just avoids any slim chances of problems.)

I wouldn't quite expect that this next install would complete successfully. I'd only expect initial elements to run through early steps that prepare the environment. If it completes, well, fine. But I'd expect to need to run the complete a second and possibly even a third time.

It's hard to know how any "flash" types of memory that support startup or boot sectors of any HDD/SSD are currently set right now. By working to {try to} ensure each setting is proper, by expecting to go through steps multiple times to force proper settings a phase at a time, you increase your chances.

Part 2:


One thing that wasn't clear in the beginning is how the install DVD was created. Was the DVD .ISO UEFI-enabled? To tell the truth, I haven't needed a DVD for any Linux installs under UEFI nor am I likely to create any. Instead I'd create a USB stick install. I mention that because install media should (needs) to be created specifically for UEFI. AFAIK, simply burning the downloaded .ISO to DVD won't work well, if at all.

I'd probably use Rufus to create a UEFI-enabled USB install. I'd have to do some looking to see what would be done to create a UEFI-enabled install DVD for Linux Mint.
Thanks tliotta - I will try to create a USB stick to install from.  I looked at Rufus but the download appears to be an exe filer.  I did not see one for Linux.  Do I need to use a windows computer.  I would have to find a windows computer somewhere if it is necessary.
Have you tried my suggestions? Burning the iso file to a DVD should make the DVD boot properly into an EFI system. It just looks as if you haven't selected the correct grub installation destination.
I'm not sure rindi, where I make sure the DVD is booting properly into an EFI system.
