Hello, I followed this method and now I can boot via USB, but when I boot it via SSD, which installed Clover, cannot boot. When I do that, the white apple and indicator appear, but after that it turned into a gray screen. My X201 has i5 560M, 8GB RAM, and 64GB SSD. I've already deleted the DSDT and SSDT's from ACPI/Patched.
Please tell me what I should do next...
