In summary, USB Boot and CD/DVD Boot have different processes for booting and installing software. With USB Boot, the computer can detect the presence of the USB and boot from it, while with CD/DVD Boot, a notification appears at the start to prompt the user to push a key. Additionally, in the case of USB Boot, the installation process can be accessed after logging in, similar to a hard drive, while with CD/DVD Boot, the installation can be done without logging in. This is normal behavior for both methods.

What are the differences between USB Boot and CD/DVD Boot. I am confused when booting from USB. My BİOS setting is set up for Legacy Mode and USB Boot but now something is different from CD/DVD boot. In DVD boot we restart PC it gives a notification at the start as push a key. Without logging in we can do the installation. But in USB case, I don't take any notification. After loggin in, under my computer I access to the setup file in the USB. The I start installation. Is this normal? Should it have been like in the case of DVD boot i.e not logging in?
