Hello Zack_The_ThinkPad_Guy,
Welcome to the Microsoft Community!
I understand that you want to create a Windows 98 SE boot disk without a 3.5-inch floppy drive.
First I need to explain to you that Microsoft has discontinued support for Windows 98 Second Edition (SE). Windows 98 SE was released in 1999 and after a period of support cycle, Microsoft officially discontinued support for it on July 11, 2006. This means that Microsoft is no longer releasing security updates or technical support for Windows 98 SE, so using this operating system may face security risks and compatibility issues. Upgrading to a more modern operating system is recommended to ensure system security and performance.
In addition, without a 3.5-inch floppy drive, if you can run virtualization software (such as VMware), you can simulate a Windows 98 SE environment in a virtual machine and create a boot disk in it.
Since virtual machine-related issues are beyond the scope of community support, if you want to learn more about virtual machines, you can go to the virtual machine module Azure Virtual Machines - Microsoft Q&A in our advanced forum, suggest specific scenarios by clicking "Ask a question", and share your thoughts, where virtual machine technology experts can provide possible solutions.
Thank you for your understanding and wish you all the best!
Best Regards ,
