Hello everyone,
I'm running Linux Lite 5.4 on an HP machine with BIOS Legacy. I've converted my disk to GPT and created a proper EFI partition. I installed GRUB in UEFI mode via terminal (no Live session available), but my firmware does not detect the fallback `bootx64.efi` file. I'm still booting using Legacy mode via F9, and I can't use `efibootmgr` because EFI variables are unavailable in my current session.
What I'm looking for is a way to force UEFI boot using only terminal tools, without removing GRUB Legacy or risking an unbootable system. Ideally, I want to activate a UEFI path that my firmware will recognize, even if it requires copying files manually or testing alternate bootloaders.
System info:
- **Linux Lite Version**: 5.4 (Ubuntu 20.04 base)
- **Memory**: 1.8 GiB
- **Motherboard**: HP 80BF
- **Kernel**: 5.4.0-216-generic
- **Graphics Chip**: Intel HD Graphics (x5-E8000)
Any guidance, script, workaround, or documentation that could help me achieve UEFI boot without a Live USB would be greatly appreciated. Thanks in advance!
