I am on elementary OS 5.1.7 and trying to install elementary OS 6 beta 2. I used Etcher to create my live USB. However, when booting up from the live USB, I am only getting a blank screen.I am on AMD A8-7680 Radeon R7. This is what running lspci inside the eOS beta gives me:

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wani [Radeon R5/R6/R7 Graphics] (rev e2) (prog-if 00 [VGA controller]) Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Radeon R7 Graphics Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at d0000000 (64-bit, prefetchable) [size=256M] Memory at e0000000 (64-bit, prefetchable) [size=8M] I/O ports at f000 [size=256] Memory at feb00000 (32-bit, non-prefetchable) [size=256K] Expansion ROM at 000c0000 [disabled] [size=128K] Capabilities: <access denied> Kernel modules: amdgpu

I tried putting nomodeset to the grub config before booting up, and it does start. However, the graphics is big and low quality. It also shows this error before showing the display:

*ERROR* VGACON disables amdgpu kernel modesetting.

I searched for this error and tried setting these boot options:

amdgpu.dc=0 amdgpu.si_support=1 amdgpu.cik_support=1 radeon.cik_support=0 radeon.si_support=0

But it does nothing. The screen just shows my motherboard's splash screen (not the eOS splash screen).

EDIT: It turns out it was a borked up Windows 10 boot loader that was not removed when I deleted it was the culprit. I ended up wiping my hard drive clean and starting over.
