A new UEFI boot record is created on each reboot - Ask Ubuntu


i dual boot ubuntu 16.04 , windows 10. bizzarely, on each reboot, new uefi boot record ubuntu gets created.

$ sudo efibootmgr -v bootcurrent: 0029 timeout: 1 seconds bootorder: 0028,0029,0000,0012 boot0000  windows boot manager  hd(2,gpt,afb0f7a3-8d09-4ccf-ad3b-553841c2f4dd,0x96800,0x82000)/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.}....g............... boot0012  uefi: (ntfs) seagate bup slim rd  pciroot(0x0)/pci(0x1d,0x0)/usb(1,0)/usb(1,0)/hd(4,mbr,0x4294967235,0xa2800800,0x46608000)..bo boot0028* ubuntu    pciroot(0x0)/pci(0x1f,0x2)/sata(3,65535,0)/hd(2,gpt,afb0f7a3-8d09-4ccf-ad3b-553841c2f4dd,0x96800,0x82000)..bo boot0029* ubuntu    hd(2,gpt,afb0f7a3-8d09-4ccf-ad3b-553841c2f4dd,0x96800,0x82000)/file(\efi\ubuntu\grubx64.efi)..bo

above, boot0028 record 1 used point grubx64.efi. on reboot, points pciroot/..., , new record (boot0029 in case) gets created. (the output of command above contained dozens of records 0028, manually removed record between 0012 , 0027 before posting here).

the boot order doesn't change machine attemps boot 0028, fails, goes uefi bios screen, , have reboot again boot.

what's going on , how can fixed?

$ grub-install --version grub-install (grub) 2.02~beta2-36ubuntu3.2 $ uname -r 4.4.0-38-generic
