SCCM OSD CREATING A STANDALONE TASK SEQUENCE MEDIA

Hi, Mujeeb, Today I have created a Stand Alone Media in USB and successfully deployed offline OSD image without Network on a Laptop but unable to login due to not accepting the Local Admin Password which we are using in our SCCM Infra Production, Please suggest the cause.

Stand alone Media is greyd out for me, how do I set the permissions.

is it possible to use stand alone media on a physical machine versus a VM? How to do load the .iso, is that even possible?
