2Have you tried to open your laptop up and go through the steps to reset its firmware settings (NVRAM/"CMOS"), just in case it's hitting some bugs while trying to find a nonexistent boot entry? What happens if you hold the usual keys while powering on the system (which will often bypass EFI "fast boot")?– grawity_u1686Commented Aug 27, 2023 at 14:45

1You could use TestDisk to recover the EFI partition.– harrymcCommented Aug 27, 2023 at 15:11

3EFI partition doesn't need to be 2GB, just the max size required for a distro plus 100MB for Windows. 512MB is what Arch recommends to cover all UEFI firmware implementations, so 627MB RAW would be the max required (the most I've seen a distro require is 768MB). Do you have CSM [Legacy] Mode enabled, as if no EFI boot options are detected, usually either UEFI firmware error screen shows or the EFI CLI shell appears (CSM Mode should never be enabled, as it' sole purpose was to support distros circa <2017 that didn't yet support EFI boot)– JW0914Commented Aug 27, 2023 at 15:42

It is vastly easier and safer to use virtual machines. These problems do not occur,– anonCommented Aug 27, 2023 at 15:49

“I suppose the menus were actually EFI executables that were in that first partition which get ran after the firmware startup, but since I deleted it, it can no longer access them.” - No, the EFI partition didn’t have executables. You absolutely should be able to reach the UEFI menus. Your idea of taking an IC out of your laptop and putting it I. Your desktop absolutely will not work– RamhoundCommented Aug 27, 2023 at 16:09

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
