Hi,

I'm assuming you're booting off a UEFI-based system and that you lost
the menu entry stored in NVRAM corresponding to "Fedora".

You can recover your boot menu entry by searching some of the logs that
Anaconda creates during installation.  Try booting once again with the
USB stick; mount your root filesystem say in /mnt and try this:

grep efibootmgr /mnt/var/log/anaconda/storage.log

There you'll see the command that was used by Anaconda to "register" the
boot menu entry.  Something like this:

efibootmgr -c -w -L Fedora -d ...

Run that same command until the end (...shimx64.efi) Confirm the entry
was created by simply typing efibootmgr.

Let us know if that works.

What I forgot to say, was that this is a F26 system,

so I can't find an efibootmgr string.

What I can see is  stuff related to my /dev/sda

and then there's blocks of info for what I assume are the 3 parts of the LVM (swap/root/home)

Here is a subset of the info that might be relevant:

I hope you can help from that.
