Re: UEFI with GPT Partition style Tool in Linux

Small detail : the EFI partition is functionally similar to the MBR on Legacy systems, in the sense that it contains the bootloader. But it's different from /boot. You will always have a /boot and it does not need to be on a separate partition. In fact on a standard linux install (eg if you choose "...

Re: Not booting. Dell inspiron 15

+1 on secure boot and fast boot. Another thing you can try is to reinstall (you have nothing to lose), choose "erase the disk and install linux mint", and later in the process do not select "Install third-party software for graphics and Wi-Fi hardware, Flash, MP3 and other media."

Re: Grub how to boot linux mint 18.3 from grub prompt

You can have only one grub in command. At first you had grub installed on the external drive, so that one was in command. Then you installed it on the internal drive, so now that one is in command. You should still be able to boot the external drive from the internal grub. To do this, you need to ma...

Boot windows, get refind and install it using the windows instructions.

Dont forget to disable secure boot before all this, if you have not done it already.

Re: Secure Boot from hard drive - Dell Inspiron 15?

Hi, actually Mint does not claim to be compatible with secure boot, and usually advises to turn it off. A possible workaround is given in the User guide : https://linuxmint-installation-guide.readthedocs.io/en/latest/efi.html i.e. do not select "Install third-party software for graphics and Wi-Fi ha...

Re: Its possible from Grub2 on MBR disc start EFI boot on other drive?

A signed kernel (vmlinuz-...efi.signed) is necessary only if you boot in UEFI mode with secure boot active. And if you do so, you will only be able to boot kernels signed by the maintainer of your shim+grub. i.e. to boot a kernel from a non-ubuntu distro, you will need their shim+grub. Some distros ...

Re: /etc/fstab + Mounting Drive = Error

One thing that could have gone wrong is the option, it's "defaults" not "default". Also it's best practice to identify a device with it's UUID. /dev/sdb may refer to another drive, eg if you plug several drives at boot, you dont know in which order they will be recognised Finally if you place an ent...

Re: Assistance for switching to Linux from windows 10

Welcome to Mint, first thing is that you dont have to learn command line to run linux (especially Ubuntu-based distros like Mint). Many people rarely/never use command line, as happens with other OSes. Now if you do want to learn the internals, this could be useful : https://linuxjourney.com/ There ...

Re: Macbook Retina Iris Pro mid-2015 black screen after boot

Maybe the machine didnt suspend but hibernate. It's indeed very frequent that hibernate doesnt work and prevents you from rebooting. I have found however that if you boot to something else (eg a live USB), the shutdown and make a normal reboot you should be fine, because booting to the live USB woul...

Ruthan, you probably have a confusion with refit which is indeed dead and states on its website "2013-03-29: As you may have noticed, rEFIt is no longer actively maintained. Please check out rEFInd, a fork that is maintaned and under active development." With grub, there are indeed various indicatio...

Re: Its possible from Grub2 on MBR disc start EFI boot on other drive?

I'm not sure I understand all your text, but it looks like what you need is refind
This is a graphical boot manager that can boot EFI loaders as well as Legacy/BIOS ones (ie MBR drives).

Strange that shim is not present, but if you successfully disabled secure boot, you can make an entry directly for grub : the EFI\ubuntu\grubx64.efi that you found It doesnt matter what bootoption name you give, this is just for display (though of course it could be useful for future for you not to ...

Humm... It's getting harder.
Boot your live USB, open a terminal and report the output of each of the following commands :

+1 on disabling secure boot, that's the most probable culprit In the firmware interface (/BIOS), you may have an option to add a new boot entry, as in the following image : https://philipyip.files.wordpress.com/2016/07/1.png If so, try to set an entry for EFI\ubuntu\shimx64.efi on the EFI partition ...
