tails-amd64-4.13.iso won't work in UEFI Mode! (Dell Inspiron 3520) #626

Tails Version 4.13 does works perfect in Legacy BIOS Mode.

But it won't work in UEFI Mode.

I can't reproduce the problem. I test it and it works fine in my laptop (both Legacy BIOS and UEFI mode).

tails-4.13-amd64.iso
md5sum: 1121970d5891d89b4a1b05bccc3ac9d4

Does other ISO files work fine in the same envrioment? (e.g. Ubuntu)

ABOhiccups commented 3 years ago

I tested on Desktop PC. Tails does work in UEFI Mode through Ventoy.

The one I tested was Dell Inspiron 3520 Laptop and it won't work with Tails in UEFI Mode through Ventoy. That's weird!

Does other ISO files work fine in the Dell Inspiron 3520 in UEFI mode? (e.g. Ubuntu/CentOS)

ABOhiccups commented 3 years ago

Yes. I tested Boot-Repair-Disk, MemTest86, Parted Magic, Kaspersky Rescue Disk, Arch Linux, and Windows 10.

Both ISOs (except Tails) works perfect on Dell Inspiron 3520 in UEFI Mode.

That's really weird! You can test a tails 4.12/4.11 iso for comparison.

ABOhiccups commented 3 years ago

Tails 4.12 was tested. Same issue happened.

What about tails-amd64-4.13.img (USB image file) ?

ABOhiccups commented 3 years ago

It boots to Grub screen perfect. But its stuck at Plymouth Splash screen.

ventoy commented 3 years ago

This is expected. But at least it boot to grub screen, no similar error happened.

I think I found the problem.

You can do the following test.

Use a VirtualMachine(e.g. VMware/VirtualBox) and set to UEFI mode. Directly connect the tails-4.13-amd64.iso to the VM. Then you will find that it can NOT boot in UEFI mode.

That is to say, the tails ISO file does not support UEFI boot itself (in ISO mode). If you extract the whole ISO to a USB drive with fat32 partition, it can boot in UEFI mode but this is not ISO mode. The developer of tails miss some option to make it support UEFI mode when generating the ISO file. (You can test ubuntu.iso in the same way, you will find it can boot normally in UEFI mode).

Ventoy use a special way to do its best to boot these similar ISO files in UEFI mode, but this special method has some compatibility issues with some UEFI firmware. That's why it works in my laptop and your PC, but has problem with your Dell Inspiron 3520.

So the most fundamental reason is that tails ISO file does NOT support UEFI mode itself. I hope the developer of tails can add support in future releases.
