Reboot before installer GUI shows up

For whatever reason, while the installer is loading, the computer just does a complete reboot.

First, my specs:

  • Intel 6200U (Skylake)
  • HD 520 Graphics
  • Unknown SSD, but I remember it being a generic Lenovo M.2 SATA drive
  • Intel WiFi (confirmed working with itlwifi)
  • RealTek RTL8211 Ethernet (through USB)
  • Lenovo ThinkPad Yoga 260

Now, this configuration has worked perfectly dozens of times before as I was testing some things to get the installer to run, but now all of a sudden it doesn't work.

It's worth mentioning that this rebooting also occurred in the successful installs when doing any of the following: - Erasing a disk - Formatting a disk - Checking a disk - Partitioning a disk - Searching the web

I can't help but feel that this issue, the aforementioned reboots, and my various issues getting the GUI to run are all somehow related. I'm getting a sneaking suspicion that it has to do with either my USB hardware, my network hardware, or my sound hardware.

This first happened when I noticed some AppleALCU.kext errors were causing other issues like the installer sometimes never getting to the GUI phase at all, and such decided to remove it and add it later. Unfortunately this caused these symptoms to start up, and even after adding AppleALCU.kext back, same symptoms.

Tried with and without -v and -igfxvesa.

Interestingly, sometimes it will get to the loading-bar phase, then immediately reboot after a few seconds.

Resetting NVRAM does not help.

Unsure what's going on and would appreciate help.

I'm unfortunately not able to post my OC directory nor my logs due to some unfortunate and unforeseen issues (unrelated to this whole debacle).

Would like to know if anyone has any suggestions meanwhile I try and get the EFI Dir and log.
