Last year we already posted about creating a bootable USB stick. In the last post we used WinImage to create the bootable USB stick to boot ESXi. Some time ago I found a tool which makes it much easier to create a bootable ESXi USB Stick. I am going to use UNetbootin to create bootable USB stick. You can download it here.
2. Select Diskimage and browse to the ESXi iso installer
3. Select your USB Drive and press oke
4. Click YES
5. Now you’re ready to start the ESXi installation.
