Help - macOS Sequoia reboots suddenly during installation with progress lost

[LordOfTheTeapots]

[ Sorry if this is in the wrong sub-forum, I am unsure which one was for asking for help, and this seemed like the one ]

Hello, I am trying to install macOS Sequioa on my laptop (bare-metal install, no VM) but during the installation process my laptop suddenly reboots, and starts up again. This means I lose all my progress in installing macOS.

I have done the following steps before this happens:

• Downloaded the vanilla image of macOS Sequoia (tried both 15.5 and 15.2) from the Vanilla Images page
• Used balenaEtcher to write to USB
• Replaced the EFI with the relevant modded OpenCore EFI (Notebook, Whiskey Lake) from the modded EFI page.
• Changed Laptop's BIOS config (SecureBoot off, Intel VT-d off)
• Plugged this USB into the Laptop and booted from it.
• Selected "Install macOS Sequoia"
• In the macOS Recovery Manager, erased my SSD and reformatted it to APFS
• Then selected the install button

The installation proceeds like normal, but when the progress bar is ~70% done, the system reboots and I have to start all over.

I have tried:

• Changing the version of macOS Sequoia
• Changing to macOS Sonoma
• Wiping partitions with GParted

In case it is relevant:

• CPU is Intel i7 8th gen (Whiskey Lake according to CPUID) - Compatitable with macOS Sequoia
• Laptop is Lenovo Thinkpad X1 Carbon

Any help would be much appreciated.

Following this tutorial, since I am very new to this:
