Hello,
The problem could be your bootable media. To test this, try another USB bootable media, and load fedora Workstation from getfedora.org on it for testing purposes. Use the fedora media writer GUI software from the same webpage to "burn" your usb. Then to be sure BIOS settings are correct enter your BIOS and on the "save and exit page" select the toggles for "Factory Defaults" BIOS parameters and "Optimize for OS" (secure boot mode should be active this way.) Then perform a cold shutdown, insert the USB while the machine is shutdown, and, finally, boot from the USB. If it boots and you are not interested in fedora distribution, you need to formulate your desired distribution's bootable media with these features:
A) Configured for UEFI booting mode, and gpt partition tables. For modern Lenovo computers, Legacy booting with mbr is no longer seamless, both during the very first boot up and then months later for operational issues. If the distribution can not be found with UEFI booting capability, it is too old and unsupported for practical use.
B) Security keys loaded for booting under Secure Boot security protocols. There are two workarounds, a) unset the secure boot toggle within BIOS, or b) learn how to self certify the media and manually insert security keys. I think both methods are equally secure.
Good Luck!

PS> I have been using linux for a couple of decades with experience with several distributions. AT&T Unix System V, Slackware, Solaris, Suse, Ubuntu, and now I use Fedora, but also Raspbian on some ARM boards. I see little practical difference between the various distributions, although the commands are a little different between the various flavors. The first distribution you succeed in booting and installing will do everything your "favorite" distribution will do.
