HP Pavilion 17 Notebook PC is a bit compicated with bootloaders. It has not option for choosing linux-bootloader grub, even if grub would be installed to the EFI-partition. A simple trick is to rename Windows's bootmgr.efi file from /EFI/Microsoft/Boot folder and copy "ubuntu's" grubx64.efi and grub.cfg files from /EFI/ubuntu folder and rename grubx64.efi as bootmgr.efi

After that grub-menu appears and you can boot into linux, where you need to run 

sudo update-grub

That makes in Pavilion 17 a grub-menu, which is far too long, so I edited the menu by hand and write-protect /boot/grub/grub.cfg file.

PS. I tried to repair bootloader using BootRepair-USB, but even it did not get the boot menu in Pavilion 17.

PS2. This happens if you do a dualboot, without dualboot, there should not be any hassle.


For getting to edit EFI-partition, you need to mount the partition first, which goes something like
