Trying to boot up by a newly created usb installer - but upon boot up after hitting F12 - When i select to boot from San Disk - there is no option to boot from UEFI San Disk - So im getting the no boot disk error - am i doing something wrong when creating UISB installer - I followed all instructions carefully
