"acpi=off" somehow broke my computer boot?

Hi, I recently tried to boot my Arch Linux with this kernel parameter to try fix a unrelated problem I had, but now when I boot my computer, the boot logo (for me it's the Dell Logo) flashes really fast and I get a black screen, grub is running in the background cause I can still select which OS to boot into with Grub by changing grub entry with Up/Down arrows. I tried getting into my bios, but I'm still getting a blackscreen and I have to shutdown manually. After a while, Grub selects the first entry and it boots up on my Arch where everything is normal.

EDIT: Since it's quite hard to explain exactly what is going I made a video here, BIOS is completely inaccessible and Grub is not showing at all. As you can see I can still boot fine on Arch so if I can provide any logs that would be useful to fix this big issue I would gladly comply.

What is going on? Everything happened after a tried booting once with "acpi=off".

Unlikely (ie, "no")
Is this a notebook? Try to attach an external monitor, ensure it supports 1280x1024 and try all avaliable outputs (dvi, vga, hdmi, dp - whatever is wired out from the device)

I've plugged my laptop with HDMI and I get no signal on the monitor when booting with the HDMI input selected.

Edit: Read your post more carefully, I see. Okay well, agreed this sounds very unlikely. Still curious, what was the "unrelated problem" you had, and what did you read that made you think turning off ACPI would be the solution? As far as I understand, that is mostly just a temporary hack to get around something, when there might be a better alternative.

Turning off acpi entirely is just gonna break things (temporarily)

@LordDrakota, is this a dualboot system? In case: did you get a windows update recently (and did that update your BIOS/UEFI)?
Does the notebooks handbook give any advise on how to reset the BIOS? (sometimes removing the battery for a longer time does, but since batteries are nowadays often soldered (and glued) there might be other ways (special key combination at boot etc.)
