Install the efibootmgr package. It allows you to rearrange the efi boot order.

You should be able to just use efibootmgr to change boot order to make 0000 first.
sudo efibootmgr -v
http://linux.dell.com/cgi-bin/gitweb/gitweb.cgi?p=efibootmgr.git;a=blob_plain;f=README; hb=HEAD
See this setting
-o | --bootorder XXXX,YYYY,ZZZZ,... explicitly set BootOrder (hex)

You have to type in all the devices with the correct hex numbers as shown by the -v command, just in your prefered order.

Is the bootmgr not found a UEFI/BIOS error? Then you have a buggy UEFI that has been manually modifed to only boot Windows but description. The f12 must bypass that bit of code so you can boot.
Vendors violated UEFI specs - http://hwe.ubuntu.com/docs/ubuntu-bios-uefi-requirements.pdf
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.
They debugged this one to see details:
Lenovo ThinkCentre M92p only boots Windows or Redhat.

(http://mjg59.dreamwidth.org/20187.html?thread=774619) Rename will occure if Boot-Repair sees Windows kernel issues, but may not always be required.
buggy-kernel detected. Do you want to activate [Backup and rename Windows EFI files]?
Rename option now under advance choices - updated Boot-Repair so that by default it will put grub/shim in EFI/BOOT/bootx64.efi only
http://ubuntuforums.org/showthread.php?t=1769482&p=12740984#post12740984
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.

i dont think its modified to work with windows only becouse ubuntu or any other linux os that is 32 bit is working fine

If you install any 32 bit versions those only install in BIOS boot mode, not UEFI. So they would work. But some UEFI are modified to only boot Windows.
