Error Invalid Parameter

Good afternoon


Before loading the grub I get the error that I attached, but after a few seconds, the grub was loaded correctly, how could I fix this error?




Thank you.

Use the instructions here https://www.linuxbabe.com/command-li...otmgr-examples to remove 0001
Then, if you wish, you can also change the boot order

Good morning
Sorry for having created two topics, I did it because in the other topic it was because the grub was not visible and it´s now solved.
I already executed the efibootmgr command before opening the topic, I deleted the entry and it,s solved but when I start Windows again I get the error again.

No problem

Try and remove the offending text only from the efi entries, where I have marked in red.
May work or may reproduce itself again?

Good night

Now I only had one Ubuntu entry, I deleted it and the other operating system booted.
I have accessed the BIOS and selected Ubuntu to boot as the first option, and when I restarted, the same error appeared again. I add the output of the efibootmgr command:

BootCurrent: 0001

Create a new entry for Ubuntu without File(.䥗䑎坏S)
Delete the existing 0001

Hello
I followed the steps but the same thing happens, as soon as I load Windows 11, I get that error before loading the grub with the list of Operating Systems.

I don't know if I should leave it like that.

Either, Windows is causing this or it is your firmware.
If you remove the offending entry and reboot a few times into Ubuntu, do you see the same error?
Do you have the latest UEFI firmware for your PC?

Good afternoon

When I delete said entry and start in Ubuntu I don't get the error, but as soon as I log in the first time in Windows after deleting the entry, I get the error every time.

The firmware is up to date.

Greetings.

Is this an HP system?
HP does not seem to accept changes from efibootmgr which grub uses to change boot order on install or update. It seems to auto reset to Windows.

Those with HP and a few others say to change boot order in UEFI settings (not one time boot menu).
