Error on boot of dual boot HP455 - start_image returned invalid parameter

Good morning all.

The laptop is an HPP455 G2 with a 1TB SSD partitioned to include a separate Data partition. Secure boot is disabled. I have installed a dual boot Windows 10 and Ubuntu 21.04 system and (with some difficulty) had it working well.

Expected behaviour: On switch on or restart the system boots into the Ubuntu dual boot screen, allowing user to select Ubuntu or Windows; if no selection within ten seconds boots into Ubuntu.

Observed behaviour: On switch on or restart the system fails to boot with the error messages as below; looping through the initial post screen and into the error message. Selecting "Esc" at the post screen allows selection of efi boot options; the third of which is "ubuntu" - this takes me to the dual boot screen after which boot proceeds into the selected (or default) OS as expected.

On first installing the SDD I installed Windows then Ubuntu. Since the system did not boot properly I used 'Boot-Repair' Advanced options and followed the directions to "change the default boot entry of your Windows bootloader ... boot into Windows then type the following in an admin command prompt: bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi . The system then booted normally into the standard Ubuntu dual boot screen. It has been ok for the past three months or so.

Today I did a restart and I was unable to boot as normal, however could enter the EFI boot options screen and select Ubuntu, which then went to the dual boot screen from where boot is normal into Ubuntu or Windows.

I again used Boot-Repair Advanced options and again followed the directions to "change the default boot entry of your Windows bootloader ... boot into Windows then type the following in an admin command prompt: bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi . This did not sort the problem out.

Full details of error message:

  Failed to open \efi\ubuntu\S - Invalid Parameter

  Failed to load image \efi\ubuntu\S: - Invalid Parameter

  start_image() returned Invalid Parameter

The Boot repair log is at: https://paste.ubuntu.com/p/YcSFTnxjVZ/

I would be grateful for any advice.

Bas S.

I have the same issue. The only current solution is installing LTS 20.04.02. I found out that doesn't have this issue of corrupting the bootloader. Photo -> corrupted bootloader

I also made a thread on Overclock.net about this: https://www.overclock.net/threads/issues-with-21-04-corrupt-grub2-bootloader.1792799/

Thanks Bas, I'm going to report this as a bug. For now it is easy enough to use F9 on start up. Really helpful comments from you, thanks.

I personally installed windows and then ubuntu and turned on autoboot, secure boot is on and works fine. I did the same steps as yours and our systems are similar I think I would suggest you to enable secure boot and autoboot otherwise I have nothing else in mind sorry

If you don't have important files in Ubuntu, you can try to install version 19 or 20.04. The grub area I installed on Pardus was not working (pardus is a linux distribution looks like lubuntu), I reinstalled Pardus, sometimes such problems can occur, I can't comment further :(

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
