IFL boot on UEFI system - no display

Post by dnlathrop »

I am trying to boot IFL on a new machine using UEFI. The GRUB screen appears offering a choice in video resolution. After that, two lines appear (echoed by GRUB) then the screen goes dark and nothing more is seen.

I found an entry in the Knowledge Base describing this problem with a solution (setting a kernal boot parameter acpi=off) but that did not fix the problem. In fact, it made things slightly worse. Without this parameter I could restart the system with Ctrl-Alt-Delete. With this parameter, the system hangs and has to be powered down.

Does anyone have any suggestions?

In case it matters, the machine is an Intel NUC8 and IFL was burned onto a USB stick from an .iso file. I tried burning MBR (legacy & UEFI) and GPT versions - both fail in the same way.

I can boot IFL and see screen output and the desktop in legacy mode.

Are you trying to boot the USB stick? Why not create it using makedisk.exe that comes with IFL?

you may need to use one of the other video resolutions or you may need the
x64 version of the IFL boot disk.

I have the image/restore collection that requires IFW be installed before the IFL bootdisk can be made. That is what I did. I created an .iso file then wrote it to a USB stick. Did I misunderstand your suggestion?

I tried every video resolution offered on the screen. I believe I have the 64-bit version. I made the .iso file from IFW-64 bit.

Incidentally, I also tried using an older version of IFL (version 3.07 I think). The newer version I am trying to run on the NUC 8 is 3.29. The older version runs successfully on an older NUC (NUC7) that boots via UEFI but it shows a dark screen on the NUC8.

The IFL x64 version is a separate download from your account (it's not included with IFW).

I downloaded the zip file for IFL GUI 64-bit and used makedisk to write a bootable USB stick. I wrote to the USB using MBR with EFI partition and tried again. It did not help.

I tried booting with different screen resolutions, with no additional boot parameters and with acpi=off. All attempts resulted in a blank screen after the initial "Loading" text immediately following the GRUB menu.

I tried two other tests with the same USB stick:
(1) booting on the NUC8 in legacy mode, which worked OK
(2) booting on a NUC7 in UEFI mode, which also worked OK

So I it appeared there was a problem with NUC8 hardware. I flashed the BIOS and that fixed the problem. IFL booted with the highest screen resolution offered and without setting any kernel boot parameters.
