Hello Officer Radif!
Welcome to Microsoft QnA! Hope you are doing well!
Regarding your concern, as of now, there are no widespread issues reported with Windows 11 IoT, Windows Server 2022, or Windows Server 2025 (24H2). However, it is always recommended to check the official Microsoft documentation or forums for the latest updates on any potential issues. To create a multi-ISO bootable USB without third-party software, you can use the diskpart
tool in Windows to format the USB drive and manually copy the ISO contents for each OS into separate directories on the drive. However, note that this method will require additional configuration to enable proper booting for each ISO. For advanced setups, a dedicated bootloader may still be necessary.
