strange problem: OS13.2 won’t install on my TP X1 in UEFI mode. The process will freeze after loading the ramdisk (which is loaded successfully). I’ve read all the other posts on this (i.e., disabling apic, nomodeset etc). None of which makes any difference. Interestingly enough, I can’t even start the rescue system.
Now this could be a problem with my usb stick, however, when I enable legacy support in the Bios, the same stick boots up just fine. I also tried the live image, which works just great as long as I am not in UEFI mode. The minute I turn UEFI back on the systems hangs after loading the ram disk (live image, installer, or rescue system).
There is really nothing in the BIOS which should create this problem. So I imagine that either the BIOS prevent the kernel from starting because of a signature problem, or that that the EFI kernel on the USB stick is significantly different from the regular kernel.
Just for completeness, I tried another usb stick, and yes this is dual boor machiene with Windows 8 on it, the BIOS has been updated, secure boot is disabled, and 13.1 runs just fine on this machine.
So you select to boot the device to EFI mode?? This usually require pressings a key during boot (F10 or F12 maybe depends on the EFI BIOS) What happens what options do you have what did you select. Depending on the EFI BIOS (not all are equal) you will have to manually chose the boot mode no mater what the system is set to.
The BIOS is set to UEFI only, so the live system starts using efi mode. If I set the BIOS to “both” the live system will start in regular mode, and work just fine.
the boot process stalls right after loading the initial ramdisk (which loads ok). Afterwards, nothing happens et all. This will happen regardless whether you try to boot the live image, rescue system or the installer.
I am aware that this could be a video issue, so I used nomodeset apic=off etc. I wonder however why the video would behave differently in UEFI mode (its Intel graphic)
