Black screen after GRUB, can't install. UEFI
I installed it via legacy mode. I could not get it to install via UEFI.
However, I patched the install once booted, thus enabling it to be booted in UEFI, by doing this:
Converting Ubuntu into UEFI mode
Note: Do not follow this procedure if your computer is already booting correctly. Use this procedure only if you believe you've accidentally installed Ubuntu in BIOS/CSM/legacy mode and you want it to boot in UEFI/UEFI mode.
- Start Boot-Repair, click on "Advanced options", go to the "GRUB location" tab.
- If you do not see a "Separate /boot/efi partition" line, this means that your PC does not have any UEFI partition. In this case, exit Boot-Repair, then create an UEFI partition (see the "Creating an UEFI partition" paragraph above).
- If you see a "Separate /boot/efi partition" line, tick it then click the "Apply" button.
- Set up your BIOS so that it boots the HDD in UEFI mode (see the ""Set up the BIOS in UEFI or Legacy mode" paragraph above).

I know there are tons of threads like this and I've tried everything i can think of that has been given as an answer in those threads.
The problem: I select the USB flash drive as my boot device, and it loads a GRUB menu, that says something like "Try Ubuntu without installing" "Install Ubuntu" "OEM Installation". I click any one of them, and I just get a black screen. I can control alt delete to restart, so my PC is not hanging.
If i change UEFI mode to Legacy in the BIOS, then it SKIPS the GRUB menu and goes straight to a graphical ubuntu installer.
I need to install as UEFI as my Windows 8 installation is as such. I can't boot it if it's set to legacy.
Note that Secure Boot and UEFI are different in my bios, I can disable secure boot without disabling UEFI. However, i still get the black screen.
Things I've tried:
1) nvidia.modeset = 0 2) GRUB_GFXMODE = 1024x768x32 3) GRUB_GFXMODE=vga=vesa 4) vga=vesa 5) A different monitor via hdmi 6) A different monitor via vga 7) Different formats of my flash drive EDIT: Some more things i've tried 8) Confirmed md5 is correct 9) Downloaded Linux Secure Remix 12.10, no difference. 10) Tried drm_kms_helper.poll = 0 11) Tried acpi_osi=Linux 12) Tried acpi_backlight=vendor
Nothing works yet.
NONE of these work, I still get the black screen.
My laptop is a MSI GE-70 with the following specs: Intel i7 3630QM Nvidia GTX-660M with Optimus GDDR5 8GB DDR3 RAM OS: Windows 8 installed as UEFI.
I believe this NOT to be a duplicate since I have tried EVERYTHING i can find, and nothing seems to work.
Does anyone have any idea what it could be?

MarkoB about 11 yearsDisk Utility shows my drive as GPT. Althought I had "Legacy Support" enabled in BIOS, I was still able to select UEFI boot device option when starting Ubuntu setup from CD-ROM drive. So HP BIOS is not strictly either UEFI or Legacy like some other manufacturers seem to have

Martin Thornton over 8 yearsThat wasn't a problem for the questioner. The BIOS is before GRUB.
