Grub2 bootloader doesn't displays correctly when using a system password in BIOS

bi flag

i have a Dell Inspiron 5447 with GRUB 2.04 installed as my bootloader, it works fine when not using a system password in BIOS, but when i activate it, the grub options disappears and i get a black screen with a "-" showing up instead of the menu

What other changes have you made in UEFI (BIOS isn't used since a decade ago)? Namely, after enabling the password have you checked the boot order is still the same? Or if by any chance a previously disabled Secure Boot has been enabled?

Nope, the boot order is the same, the grub shows up normally when i disable the system password, but when i enable it, i get just a black screen with a "_", i think this image will help to explain what i mean: https://imgur.com/a/sYgLbn8 When i disable the system password, instead of this "-", the grub menu options shows up again; also: when i press enter in the black screen with the "-" my linux boots up, i think the password prompt from my uefi is somehow interfering with grub

No need for the image, description was enough and it's a well know situation :) I'm afraid I'm out of ideas though, other then up`dating UEFI as this is probably a quirk with a potential to affect different OSes so it's something that should be a priority to solve in newer versions.

alright, well thanks for helping me i think i will have to leave system password disabled for now

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.
