dear, i am talking about choose the os boot option, i am talking about advanced start up option, like SAFE MODE, SAFE MODE WITH NETWORKING, ETC.

HI, I have tried with "Nosafemode" software, it is working perfectly, but i have some concerns with this software: 1. It has to be install every machine. 2. How can we deploy the software on more than 3000 clients. 3. For every client we have to block manually and set the password. 4. If System's OS goes down then how can we disable this software on particular machine. 5. Is this a recommanded software ?
