Hello everyone.
Thank you for your attention.
I own a PC running Windows 10, and I installed Ubuntu on it. Now I want to reinstall Windows 10, but I'm facing difficulties.
I made a bootable USB from my MacOS laptop and formatted the drive to FAT and FAT32.
However, when I attempt to boot from the USB, I encounter this message:
"An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press any key to restart."
I added the USB to the boot order first, then changed it to "Legacy Only" and "UEFI Only," but nothing in my BIOS manual seems useful.
I don’t know what else I should try.
My BIOS model is B450 AORUS PRO, version F64a.
Anyone have suggestions or solutions? I’ve been dealing with this issue for several weeks.
I would begin by employing the bios tool to wipe your OS drive, followed by using a USB stick equipped with a W10 installer for the fresh installation. You might also have to reset the CMOS.
Hey, thanks for your answer. Do you know some tutorials for this? Because I have no idea about how to do it.
Ok, clear the CMOS is just remove the battery. But secure erase your OS drive, no idea.
Don't do it, your problem is the usb drive not being recognized, wiping your os drive will just make your PC not boot up into ubuntu either so it will be useless until you would be able to fix this.
If you followed a link to make the usb stick in macos then link that so we know what exactly you did, otherwise explain it as best you can.
If your bios is set for secure boot you have to also reset the keys for it to boot to a new secure medium.
If you are familiar with wine on macos run rufus and try making an usb with that.
Here is the tutorial:

This only functions if the USB is already ready to boot, which isn't the case for all devices. Treat a USB just like a hard drive and create an active partition on it for it to be usable. Consider trying other USB drives or following instructions on how to properly activate a USB drive. Begin with Windows Server Essentials

Proceed with caution if you choose the incorrect drive, as it may destroy your main operating system. The key command is 'create partition primary' to generate a bootable partition. Avoid using the sources folder; only proceed when the USB boots successfully. Also, I’m unsure whether the split file method will work.
Hi, thank you for your message. I understand you're trying to make a bootable USB from your MacOS laptop but are having trouble with the instructions.
For W10 you don't have to do much. Just use a Fat32 formatted USB stick and copy the Windows 10 ISO contents to it.
Note. I mentioned CONTENTS, not just the ISO file. It should be able to mount the ISO as a virtual disk on Mac or Linux.
It's not the same. You need to handle several steps. Initially, you can't simply copy the ISO file into the USB drive since it's too large (named ./sources/install.swm). You'll have to divide it into install.swm and install1.swm. After that, ensure the USB is recognized as a bootable device (this seems like a challenge for you). Creating a bootable USB on macOS isn't that straightforward either.
The issue is that there aren't many MacOs users here, I believe.
Most partition tools can make a primary partition on a USB drive, but I'm not sure which ones are available for MacOS.
