Can't boot to USB/CD Gigabyte 78LMT-USB3

[LETTER]

Tried unpacking and putting on a flash drive, didn't want to boot.
Figured no UEFI, time to look up a fix, got syslinux & grub packages and added to flash drive, still didn't boot.
Decided to yolo it and burn it to a disk and try to boot there, didn't work.
Went to steam repo and got SteamOSDVD, burned to disk, still won't boot.

Any ideas on how to fix this?

How did you burn the SteamOSDVD to a disk?

You'd need to use something like imgburn and burn it as an image, instead of dumping the iso on the disk as a file. I dunno if that's what you did, though.

Some burning tools are also not very good at doing that.

I used IMGBurn to burn iso to disk which came out as:

That's a hybrid EFI dual bios board. Yuck. Same as me but AMD socket (roughly). Let us know how and on what OS you made the DVD or zip. The zip archive process is generally just extracting the contents of it to a freshly formatted FAT32 drive.

See:

Win 10, and Did zip process by extracting to a formatted FAT32 8GB flash drive, just auto booted into windows.

(Tried again using a video I found on YT to install for UEFI systems by moving Syslinux Win32 & mbr files to syslinux folder on root drive and moving grub packages.deb into a grub folder)

Did zip process on CD by unpacking all contents to a folder going into that folder and packing them into an ISO then burning to CD, auto booted into windows.

Downloaded SteamOSDVD and burned to CD via IMGBurn and it auto booted into windows again.

Un-sure of what to do at this point, had the same thing happen to me when I tried making a hackintosh on this PC.

Hmm, looks good, that disk should work.

The system will automatically boot from the hard disk, though, you'll have to change the boot order in the bios to change that.

I did, it's currently set to CDROM / USB-HDD / USB-ZIP.
It just auto boots to windows and skips the CD completely, and not giving me any messages about it at all.
Kinda like the CD doesn't exist.

EDIT:
Tried it on an old PC like a really old 2002 PC and it'll load the disk??
GG modern technology?

ohh, nice

Fixed, apparently if there's an OS on the system it won't boot, the other PC didn't have one so it booted to CD. Unplugging then booting and plugging back in once booted fixed it.

Currently have a new issue however, I'm on a Philips HDTV (1920x1080) and it has an over scan issue that I fixed with nVidia control panel (Resize desktop), any way to fix this within SteamOS without dropping to a funky 1360x786 res?

Could you post the output you get when running the xrandr command from the terminal on the desktop?

@TinMan It's fine, I'm happy my pc rebooted before I responded to that lol.

@Shark WIthin BPM it's fixed because I can scale the resolution during setup, however on desktop mode it over scans. I tried running term on Desktop but it won't open. I'll try again now that it's fully setup.

Hopefully I'm reading this correctly :)

Was wanting to leave out the giant jumbled mess of resolutions but I figured it was going to be wanted and wanted to get it over with incase it was lol. Basically, parts of the image are off screen, with the resized version I have on windows I think it's like 1863x768/1080/1368? something like that.
