Hi Steve Thanks for your reply. Here are the outputs for this Envy notebook - now running Zorin OS as this installs and has a "Grub repair" feature on its USB install stick - usually fixes all HP shenanigans. BootCurrent: 0000 Timeout: 5 seconds BootOrder: 0000,3000,0001,0002,2001,2002,2003 Boot0000* ubuntu HD(1,GPT,ca9d4c6c-f90a-408b-9a27-1559c1619904,0x800,0x100000)/File(\EFI\ubuntu\shimx64.efi)RC Boot0001* Network Adapter (IPv4 UEFI) PciRoot(0x0)/Pci(0x1c,0x6)/Pci(0x0,0x0)/MAC(a0481cc2def7,0)/IPv4(0.0.0.00.0.0.0,0,0)RC Boot0002* Network Adapter (IPv6 UEFI) PciRoot(0x0)/Pci(0x1c,0x6)/Pci(0x0,0x0)/MAC(a0481cc2def7,0)/IPv6([::]:<->[::]:,0,0)RC Boot2001* USB Drive (UEFI) RC Boot3000* Internal Hard Disk or Solid State Disk RC Boot3001* Internal Hard Disk or Solid State Disk RC Boot3002* Internal Hard Disk or Solid State Disk RC Boot3003* Internal Hard Disk or Solid State Disk RC Boot3004* Internal Hard Disk or Solid State Disk RC I ran your command on another HP Pavilion dv6 that also has grub failure using Ubuntu. It replied "EFI Variables are not installed on this system". I checked BIOS in detail on both notebooks - no mention of anything unusual. This second dv6 also had Grub install failure with Ubuntu and also Mint 19.3 - based on Ubuntu. It now dual boots Zorin OS and Mint 19.3. To accomplish this I installed Zorin OS first, used its Grub repair feature, installed Mint 19.3 for dual boot and Grub install failure occurred. I used Zorin OS Grub repair on its USB install pen drive to get Grub to work, now both OS are happy. *I agree that this is definitely intentional by HP to motivate consumers to buy another notebook - they hope one of theirs*. No way! Not Ever again Steve! Other anti-consumer behaviour - battery charge failures - proprietary 3-pin connection on this Envy. It is impossible to wire in any other 19 V supply - I tried this, it doesn't respond. I waited a week, it stopped playing silly games. I am quite certain given all this that HP Intentionally is motivating consumers to ditch older notebook and buy another. They especially target Ubuntu as I have described on several incidents, all based on Ubuntu. Thanks for your assistance Steve. Although I have a workaround there may be others who don't - If I can help others with HP shenanigans, no problem. Lastly, on an older Acer 5920 notebook - never a problem. I use this one to try lots of different OS, often. This behaviour is specific to HP. Ian On Tue, Jan 7, 2020 at 7:30 AM Steve Langasek
