Recent update causes problems. HP laptop 15 won't boot to grub.

After a recent update my HP laptop 15 with Linux Mint 18 won't boot into the grub. I have to press ESC and go to bios and then pick uefi then pick the grub. Everything works fine after that. However then after I shut down I have to go through all that to boot up again. What should the TPM settings be ?

Was the update hardware or software? I have a similar issue with my first SSD. Although this system seems to be quirky about that relative to GPT and DOS partitioning schemes. At the moment I boot a usb to boot the SSD, even though grub is on the SSD (in the MBR, but GPT partitioned).

The update was the ones that come from Linux, that shows up in the Shield icon in the system tray.

Did you have to do anything with copying files in /boot/efi when you installed to get it to boot linux?

As at happens, I had a HP laptop with a Mint update waiting, so I just ran it - it did have a grub update, and popped a confirmation screen to add new (grub) components. Worked fine for me.

From a terminal run "sudo efibootmgr" and post the output (install efibootmgr in need).

Here is the results.

BootOrder: 0000,9998,9999
Boot0000* Windows Boot Manager
Boot0001* USB Drive (UEFI) - CD/DVD Drive
Boot0002* USB Drive (UEFI) - Hard Drive
Boot9998* Internal CD/DVD ROM Drive(UEFI)
Boot9999* USB Drive (UEFI)

Was this supposed to be a dual-boot with Windows, or did you delete Windows ?. It looks like the latter. You should have a ubuntu entry in there as well - yes (also) Mint uses that label.

I deliberately broke a laptop so it was similar to you - a simple "grub-install /dev/sda" fixed things. I was concerned it wouldn't handle the EFI partition properly, but it did. For some reason took 2 re-boots to get the touchpad working - may have been coincidence.

Yes I wiped out Win 10. The "Ubuntu" option comes up then the grub option. So you are saying to install grub again ? What would be the exact terminal input for that command ?

Ok, then you should simply add your grub entry to this list of boot loaders. You have a UEFI booting system, so a simple grub-install on /dev/sda will not work.

Just check the location of your grub boot loader on the EFI partition (mounted at /boot/efi/). It is usually

Code:

/boot/efi/ubuntu/grubx64.efi

Well, just verify that and register the UEFI binary (.efi file) into the list of UEFI boot loaders:

Code:

modprobe efivars
modprobe efivarfs
efibootmgr -c -g -d /dev/sda -p 2 -w -L "GRUB" -l '\EFI\ubuntu\grubx64.efi'

The above example assumes that the EFI partition is /dev/sda2, this is why you have "-d /dev/sda -p 2". Just replace with the parameters from your system.
