In this HP it is possible to find menu where you choose current boot option with devices and partitions, but no possibility to change priority and then there's BIOS menu where you can change priority between devices, but no partitions mentioned.

In my UEFI computer, I only had an option for "OS boot manager", "Internal DVD/CD drive", etc. OS boot manager only boots windows. The only way to boot ubuntu is by using the "one-time boot option". Is there a way to make my computer boot ubuntu as a priority, and then windows?

If you have secure boot turned on, then UEFI menu will only show secure boot options. Then only if Ubuntu is installed in secure boot mode would it be an option.
But if secure boot is off, it should give more options.
But some systems have defective UEFI. First try UEFI/BIOS update to see if vendor fixed it. And then complain to vendor that their UEFI is not per UEFI standards.
PDF file:
Vendors violated UEFI specs - http://hwe.ubuntu.com/docs/ubuntu-bi...quirements.pdf
You may be able to go in with command line tool to directly edit UEFI variables with efibootmgr.Firmware should not enforce any boot policy other than the mechanism specified in Section 3 of the
UEFI 2.3.1 specification [UEFI 2.3.1]. Specifically, firmware should not modify boot behaviour de-
pending on the Description field of the EFI_LOAD_OPTION descriptor.
This was to delete a specific entry, but commands exist for just about anything.
# from live CD and use efibootmgr
sudo efibootmgr -v
The "-v" option displays all the entries so you can confirm you're deleting the right one, and then you use the combination of "-b ####" (to specify the entry) and "-B" (to delete it). Examples #5 is delete:

You should be able to change boot order.
Example 3 uses their example, just change to your devices.
http://linux.dell.com/cgi-bin/gitweb...README;hb=HEAD
efibootmgr -o 3,4
Yours should be ?
sudo efibootmgr -o 0,1
And then see if boot order has changed and then if booting changes.
sudo efibootmgr -v

I do not know what the 3d setting is, perhaps the changes confused current setting? Or now you have a 3D computer?

Is secure boot on or off? If on then setting may default to something else.
It seems like it is now skipping the Ubuntu entry and going to Windows. And for some reason going into repair mode.
Perhaps you have one of the buggy UEFI. Is it the current version from the vendor?
Then you may need to use the rename function in Boot-Repair. That makes the shim file be the Windows efi file. Then from grub you boot the backup Windows file to get to Windows.
Boot-Repair automates the rename, but you can do manually.

So this time installed 12.10, then booted again from liveCD, made backup of (efi part)/EFI/microsoft/boot and copied all files from /EFI/ubuntu into it. Then renamed /EFI/microsoft/boot/shimx64.efi to bootmgfw.efi. And it works
available as a "Rename Windows EFI files" option in the Advanced Options for the few UEFI that are modified to only Boot Windows efi file.
To perform this, just run Boot-Repair --> Adv options --> tick "Backup and rename EFI files" --> Apply
To undo & to rename files to their original names, you just need to tick the "Restore EFI backups" option of Boot-Repair.
A user disabled secure boot, and unchecked it in boot-repair. It now bypasses Grub and goes straight in to Windows.
Other buggy UEFI, now older:
Some Toshiba's will not boot.
they managed to leave the signing key out of the database that's used to validate binaries
Lenovo ThinkCentre M92p only boots Windows or Redhat.

@Jonathan Precise It may be firmware does not like being told what to do by efibootmgr!?
Try installing rEFInd which is much more reliable.

The difference between knowledge and wisdom is knowing what to do or just doing it. I know nothing and get little done.
