Jika Anda tidak ingin berpindah-pindah file boot , Anda dapat mencoba mengubah urutan boot secara manual:
Masuk ke ubuntu secara manual dan periksa urutan boot saat ini dan ID mereka menggunakan:
sudo efibootmgr -v
kemudian ubah urutan boot menggunakan -o dan ID's (dalam urutan boot dari kiri ke kanan):
sudo efibootmgr -o 0000,3000,0001,2001,2002,2003
Contoh :
1. Tampilkan pengaturan boot saat ini
$ sudo efibootmgr -v
BootCurrent: 0001
Timeout: 2 seconds
BootOrder: 0001,3000,0000,2001,2002,2003
Boot0000* ubuntu HD(2,GPT,c451cb3c-a684-45ac-9925-4046e57c40cb,0x145800,0x82000)/File(\EFI\ubuntu\shimx64.efi)
Boot0001* Windows Boot Manager HD(2,GPT,c451cb3c-a684-45ac-9925-4046e57c40cb,0x145800,0x82000)/File(\EFI\Microsoft\Boot\bootmgfw.efi)WINDOWS.........x...B.C.D.O.B.J.E.C.T.=.{.9.d.e.a.8.6.2.c.-.5.c.d.d.-.4.e.7.0.-.a.c.c.1.-.f.3.2.b.3.4.4.d.4.7.9.5.}....................

2. Ubah urutan boot (kami ingin memulai ubuntu terlebih dahulu, yang akan menampilkan menu boot saat startup):
Perhatikan bahwa percobaan pertama memberi kesalahan karena tidak dapat menemukan Boot2003 (drive floppydisk?), Seperti yang Anda lihat adalah diciptakan kembali setelah reboot sekalipun.
$ sudo efibootmgr -o 0000,3000,0001,2001,2002,2003
Invalid boot order entry value: 0000,3000,0001,2001,2002,2003
^
Boot entry 2003 does not exist
$ sudo efibootmgr -o 0000,3000,0001,2001,2002
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0000,3000,0001,2001,2002
Boot0000* ubuntu
Boot0001* Windows Boot Manager
Boot2001* USB Drive (UEFI)
Boot2002* Internal CD/DVD ROM Drive (UEFI)
Boot3000* Internal Hard Disk or Solid State Disk
Boot3001* Internal Hard Disk or Solid State Disk
Boot3002* Internal Hard Disk or Solid State Disk
Boot3003* Internal Hard Disk or Solid State Disk
3.Reboot. Menu boot seharusnya sekarang muncul. (2003 ditambahkan kembali secara otomatis):
$ sudo efibootmgr -v
BootCurrent: 0000
Timeout: 2 seconds
BootOrder: 0000,3000,0001,2001,2002,2003
Boot0000* ubuntu HD(2,GPT,c451cb3c-a684-45ac-9925-4046e57c40cb,0x145800,0x82000)/File(\EFI\ubuntu\shimx64.efi)
