1. I used USB Writer since it's a good tool as well as being simple and effective
2. Just your standard 2GB USB.
3. No
4. Using the Wiki for reference but I can basically do it mostly from memory.
5. Yes I am booting in UEFI mode. This just happens randomly when I'm in the live environment.
Doing an Arch install from memory...
Impressive!
1. When you say during the boot process - do you mean the live image boot, or the hard disk boot?
2. Did you verify you're in UEFI with the efivar -l command?3. Are you sure you have a good arch image? have you tried booting on a different machine, if not I might recommend a new image.
4. I would suggest starting again and following the wiki, since you didn't follow the wiki, I have no idea how to gauge what could have went wrong...
I can tell you from experience, the solution is not enabling the nomodeset flag... That just deals with the display settings and you don't even have a terminal yet, let alone xorg...
