How the fuck do I do it? My PC refuses to fucking boot to the USB which I have Windows 7 on.
Been goodling for about an hour now, and apparently I need to disable uefi.
But my mobo don't allow me to, I just have UEFI or legacy + uefi. I currently have legacy + uefi activated but the only usb that shows up is uefi: usb cd/dvd and not the "normal" one.
Ain't nothing wrong with the usb, I've done this shit a thousand times, just not from 8 to 7.
I remember having problem last time I tried to install 7, can't remember what I did to fix it though.

If I just run the ISO or 7 directly inside windows 8 I get the following message upon highlighting any of the harddrives except for C: (Which FYI I don't want to install windows 7 on since 8 is already on there).

Code

windows cannot be installed to this disk. the selected disk has an mbr partition table. on efi systems, windows can only be installed to gpt disks.

I also tried running it from a CD, but that didn't work either. It still only "detects" the uefi cd/dvd, just like the usb cd/dvd.

mobo is z77a-s03

You need to install Windows 7 first then Windows 8 on a different partition. If you do otherwise, you will have to mess with boot options. Make to disable Secure Boot.

That means I have to wipe my C: drive completely, install Windows 7 and then 8 again <_<

Why though?
Why can't I simply install Windows 7 on another partition when I already have w8..

If you install Windows 7 64-bit and turn off legacy boot then your problem will be solved only 64-bit version of the Windows 7 support UEFI firmware.

How am I suppose to install windows 7 when I can't even boot onto the USB drive?

The reason you cant boot to USB because you enabled Legacy + UEFI mode and you try to boot from 32-bit Windows 7 bootable USB which does not support UEFI. If you want to boot to 32-bit Windows 7 bootable USB then only enable Legacy BIOS mode and disable SecureBoot features. If you want to dual boot 64-bit Windows 8 and 7 then enable UEFI and disable SecureBoot features to boot from 64-bit Windows 7 USB. If you still cannot boot from bootable USB then create new bootable USB with RUFUS software but make sure for 64-bit Windows 7 RUFUS creates UEFI bootable USB. You must install the older operating system first, and then install the more recent operating system. If you don't you can render your system inoperable. This can happen because earlier versions of Windows don't recognize the startup files used in more recent versions of Windows and can overwrite them.

Aight so I'll try to download the 64bit iso and try that.
Also I can't enable safe boot in the first place without activating "windows 8 features" which don't work either because it couldn't recognize my GPU.
I also don't have the option to have legacy only.

Sorry but i can't understand what you mean by you cannot enable safe boot what is safe boot?
What you mean by activating "windows 8 features" what features you cannot enable why safe boot affect activation.
Disabling UEFI mode will enable legacy BIOS mode also enabling Compatibility Support Module (CSM) will enable legacy BIOS compatibility.

Do you even know how modern BIOSes look & work?

Do you?
What makes you think i don't know how UEFI firmware works. Instead of insulting my knowlege of the modern PC technology why don't you share your knowlege and teach me what is modern BIOS firmware and how it works. It will be very funny if you have no clue about BIOS/UEFI firmware but you still thing i have no or less knowlege then you.

"What you mean by activating "windows 8 features"
It's a setting in the BIOS.
"Sorry but i can't understand what you mean by you cannot enable safe boot what is safe boot?"
You literally said safeboot in your post..

I have found 3 guides for you. Check it out.

Already checked all of those, I'll try to download the 64 bit iso.

Could you tell us, please, why you need to Windows OSes?

Because of compability stuffs. What does it matter doe?

I never ones in my posts mention anything about word "safeboot" before you. I said SecureBoot features. Only reason i mention "safeboot" because you were talking about safeboot which i thing you type it wrong i thing you were talking about [b]Secure Boot[/b.] Now there are god knows lots of settings you can configure in BIOS/UEFI firmware there is no way i or any person can know every settings for hardware in BIOS/UEFI. I newer heard or seen setting about "windows 8 features" in BIOS or UEFI firmware i have no idea what features UEFI or BIOS can configure for Windows 8 OS but when talking about "windows 8 features" its usually features like Metro interface or Start Screen lot more to name then all here.

You could run a VM for one of OSes. It will avoid doing dual boot.

But I won't be able to run certain things that need a lot of resources.

Alrighty then. But yeah I meant secure boot.
That setting only becomes available upon activating something called Windows 8 features or something. I'll try to snap a pic of it once I get home, it's weird and I don't get it.
Also I only have 2 options for uefi
1) UEFI only
2) Legacy + UEFI

If you want to install 32-bit version of Windows 7 then boot the laptop or PC in a BIOS-compatibility firmware mode by enabling "Legacy + UEFI" mode also disable Secure Boot. If you want to install and dual boot 64-bit version of Windows 8 OS and 64-bit version of Windows 7 OS then enable "UEFI" mode and disable Secure Boot. With RUFUS software create UEFI/GPT Windows 7 bootable USB drive.
