PC will only boot to BIOS

[Cracker_T]

In my view im like 90% sure that your USB bootable drive is not valid , i dont know what else it can be. If you have access to a Windows system you should try install the "Windows installer" on a good USB with "Create installation media for Windows" and if it doesnt work we can see from there. (or you can try to create an USB with Linux)

You were right. I didn't install win10 on the mac correctly. So far so good. Will update if I need help - thanks!

it's one or the other. you cannot enable CSM AND UEFI simultaneously


that's normal. CSM will list all drives whether they are actually "bootable" or not. In my experience, if you were to select a drive that has nothing but data on it, no OS, it would go the next drive in the boot order until it finds one with a bootable OS


exFAT?! you need the USB drive to install Windows to be either Fat32 or NTFS....I just don't remember which one off the top of my head. Regardless, if you made the USB install drive correctly it would have been formatted correctly by Windows Media Creation Tool.

You can have both , but it wont do anything if the media is not a valid boot drive and if you dont select "UEFI only" you may end up installing Windows in legacy mode.

He is trying to create the USB from MAC , i dont think Windows Media Creation Tool works on MAC and i think he is just not doing it right.

Edit: I liked the MSI CLICK BIOS that you could use from Windows , i had that on some older intel computer , you can make things fasters ( i still do my settings directly from BIOS but it was nice touch for people less familiar with bios) , i am not sure if it still exists and its only on intel boards or its just gone.

It does work on mac, the easiest way is to do it via exFAT. The harder way is MS-DOS using terminal. I was just being a mega noob.

So yea I'll back you up it is possible to make this in macOS since I did it when I didn't even have a PC, but exFAT is sure as shit not a compatible format to boot from on a PC for installing Windows. That's at least part of the problem. I've long lost that knowledge on what hoops I jumped through to get it to all work. I recall a program called "Brigadier" was needed, but google suggests it was for getting resources for installing Windows on an Apple system....I cannot remember what steps I took to make the install media....honestly that might mean there were no special hoops to jump through. I remember the install process being a bitch, not the creation of the USB media creation tool install drive, or even what I did on certain occasions, burned the ISO to a DVD lol. If you need any advice setting up the USB install drive and you HAVE to do it via macOS I recommend asking for help over on https://forums.macrumors.com/

otherwise just make it on a Windows system where everything about this process "just works" ......as an Apple user would say

ok lol I stand corrected! I think I had a wire crossed when I wrote that reply. Thinking out loud now..... a modern MB is going to be using a UEFI "BIOS" no matter what, right? CSM enables compatible system module which acts much like a compatibility layer for "legacy" BIOS prior to the introduction of UEFI. I've used CSM on my Z390 system due to at the time I was running Windows 10 on an 2009 Mac Pro so it was installed via MBR instead of GPT. I stuck that same exact drive in my Z390 system and needed CSM on in order to use it because of how I had to install Windows on an Apple system that was not UEFI. But turning on CSM doesn't "disable" UEFI, it just allows older non UEFI compliant stuff to work/boot....so yea, idk wtf I was thinking when I wrote that lol.

Please do correct me if I'm off on my understanding of this.

I have a H670 motherboard (same socket as the TC) and I couldn't enable UEFI until CSM was turned on.

What compounded the issue was even though my Alderlake CPU has integrated graphics you cannot turn CSM on if your only running integrated (you have to use a dedicated card which luckily I have). Intel disabled CSM unless you have a dedicated card
