On Server Exchange 2019 this does not work. The ISO file is 6 gb and this causes issues with ISO to USB programs like Rufus. Those at 4 gb like standard Server 2019 not a problem.
if only if it where that simple on an Hp server bios firmware does not allow unsecure boot
Thank you for helping me find the right solution for what should have been so easy. I have been struggling through multiple applications for hours trying to burn the WS2019.ISO to a USB. I have changed computers and forgotten about this application Rufus. What a great and simple tool. As it should have been! I’m an IT provider trying to load a Server for a client and I struggled with this for way too many wasted hours… I’m so mad at them and happy with you!
Thanks,
Mark
