Hi Phillip Thanks for all your help. Unfortunately, what you suggested did not change anything. It is still booting straight into Windows unless I go via the F12 boot menu. So I have done some tests.
Here is the output of efibootmgr -v after running sudo efibootmgr -o 4,8,0 BootCurrent: 0004 Timeout: 6 seconds BootOrder: 0000,0004,0008,0003,0002,000A,0009,0001 Boot0000* Windows Boot Manager HD(2,1f4800,82000,c380ecc2-e19f-41f3-94ff-c1bb937d71dc)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.}....................

Some how it is happening automatically. I will reboot again now and take a snap of the F12 boot menu again and upload it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1469245 Title: Following install GRUB menu does not appear on startup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1469245/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
