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!]]>

I'm trying to run a Live System version of Linux Lite off a USB on a work Lenovo thinkpad x13 which is running Windows 11 and is bootlocker protected with TPM2.0.

I can boot it by turning off Safe Boot but then it's a pain as when i try to boot the windows partition it asks for a BitLocker recovery key.

I can also boot it with Secure Boot by enabling "Allow Microsoft 3rd Party UEFI CA" in the Lenovo Bios, but for some reason that still triggers Bitlocker recovery when booting into Windows?

Has anyone found a solution for this? Why should bitlocker care that 3rd party is enabled, it's still a certified secure boot? Is it to do with the TPM? I would love to just be able to boot off the USB without going into the BIOS everytime. Thanks in advance!]]>

i did a sudo apt-get dist-upgrade and it ended up messing up grub. so i can only get into the system with a recovery usb.  Because if i try to boot regularly i will end up at grub resucue.

this is the code i get when i try to run sudo apt-get grub-efi:

I only want to inform you that my Linux Lite 6.6 is very slow when booting. Compared with Windows 10, the time that I must wait is more or less double the time compared with Windows 10.

But the apps are quicker in Linux Lite 6.6 than in Windows 10! In Windows 10 it was really very slow or 10x of time!

I only want to give my feedback about this situation with the Secure Boot and know if this is happening with anyone here!

This Linux Lite 6.6 is used every day by my mother and is now adapted to Linux Lite 6.6 because Windows 10 was very slow, taking 15 minutes to open the browser Google Chrome.

In conclusion, I'm very satisfied with this Linux Lite 6.6 and my mother too!

Congratulations to the people who do this distribution!

Thank you very much!

Best Regards!]]>

After the install was done, booting the machine doesn't automatically start LL.  It just stops with a blinking cursor.  No other OS on the machine.

If I press F11 at boot for the boot menu, it doesn't show the grub menu I am used to but there is an option to boot Ubuntu.  If I select this, then LL will boot ok.

So my questions are why doesn't LL start automatically and how can I get the grub menu to display automatically at boot with this UEFI stuff?]]>
