Yes, you should definitely use those. I've always included them in the few successful run throughs I've done involving Windows 7 with UEFI mode and have not had any issues like what you're describing.
So I've done just that but still couldn't get past "Starting WIndows", verbose file allowed me to see the two yellow lines again.
DO NOT remove vga.sys. While it is a way to get UEFI mode working, you have to do a lot more steps. In addition, if you need safe mode, check disk, or get a BSOD, you won't see those at all. All you'll get is a black screen.
Yeah this is too risky for me, I plan to keep this computer for a long time so I need something stable in the long run.
After doing some testing today, I've again confirmed that doing 1st part of installation (until reboot) in UEFI, then switching to CSM without installing UefiSeven patch for 2nd part(when HDD take over), allowed me to finish installation and successfully boot windows.
I could check that the system was in UEFI with bcdedit (path \windows\System32\winload.efi\), and I could create partition bigger than 2To.
But after rebooting, it get stuck at "Starting WIndows" with or without CSM.
Also I couldn't make recovery works, whatever I did (Tested with Boot keys in UEFI, BIOS, and even a restoration disc I created before rebooting.
Is there maybe some other options in BIOS I should look for? Or maybe the 2016 ISO could work?
Edit: Just saw there is a 1.30 version of the UEFISeven patch, I'll use it tomorrow and see if I have more luck.
Edit2: Well, that removed the first yellow error, but still stuck because of VGA.
Seems like a dead-end for me, I'll give up UEFI for now and try a MBR installation with CSM, I'll post in the other topic in case I encounter any issue.
Edit3: So might be a bit HS, but I think I should share what I found during my MBR installation.
After completing installation and first boot done, I was greeted by an endless "Windows is starting" upon restarting.
I found out that I needed to disable HD Audio in BIOS settings, and now it's rebooting without issue.
I don't think it would solve VGA error from UEFI installation, but we never know.
As for me I'm done with testing, i'll stay with what I have for now.
