Fedora30 installed on USB pendrive, seems to took control over my BIOS-UEFI

Notebook Ultrabook Samsung NP530U3C

this notebook was working just fine, booting normally,
and with the UEFI/BIOS (A Phoenix one) with no problems.
Every time I wanted to enter the bios setup, I reset the computer,
then F2 while the bios logo was on screen, and done.

Yesterday, I decided to install Fedora30 in one of my pendrives.
(yes, in a pendrive, just like if it were a normal drive)
So, I used two pendrives… in the first one, I’ve put the Fedora30 ISO
(and, for that matter, it was booting and working perfectly in LIVE mode)
and the second one, was the target for the instalation.
The idea was installing and using the Fedora on that second pendrive,
booting from it, and, at any time, remove the pendrive,
and boot from the SSD inside like before;
this way, leaving the Notebook ‘untouched’. So… didn’t work.

The installation process went well, and the system is working perfectly even now
(I’m writing this from this same Notebook, with this Fedora30 system working perfectly)

The problem is when I remove the pendrive and reboot the notebook…
When the BIOS logo appear, I press F2, but there is no way to enter the bios setup…
F4 is recovery: nothing either. I tried F1 to F12, quicky, slow, no matter what,…
it’s impossible to enter the bios setup or alike… and always end up in a menu that seems to be
part of the BIOS program, that it’s has an Entry with the name Fedora, but, obviously, cant boot, cause the pendrive is not connected. Every time I connect the pendrive, the system boots correctly and it’s working, but without the pendrive, it’s impossible…

This is what I see when trying to boot without the pendrive with this instalation:

I don’t think that I’d overwrote the boot sector or bootloader in the SSD inside,
but even in that case, the problem is not that the computer it’s not booting… the problem is that I can’t access the bios configuration, and it’s only booting from the pendrive with this installation… I can’t boot with other pendrives with CentOS ISO, for example, or any other distro… the BIOS seems to be always waiting for the fedora USB that has this instalation, and I can do nothing to change that. I don’t understand what happened…
Fedora touched my BIOS/UEFI and take control over it?
I took another pendrive, and cloned over it the MBR and the ESP partition from the pendrive with this instalation, and in that case, it boots… I think that I can problably figure it out a way to put another distro on that pen, mantaining those first sectors from this installation, but that it’s not the point… the point is: Suppose I lose this pendrive with this installation… my notebook is a brick, cause is only booting that (it’s problably looking for a specific UUID and ESP partition) and I can’t enter the bios to change it… so, I know that probably I can do something from this system with efibootmgr or something like that… but suppose I cant access to this pen anymore… is then my notebook a brick? what Fedora did? Why I can’t accesses my BIOS anymore?

here is the fdisk output (
sda is a ssd inside, that has and old linux instalation…
doesn’t matter right now.
sdb is a pendrive with the current linux instalation.

I’v also removed the BIOS battery for at least three hours, but same.

If you need some additional information, just tell me

This is probably the most problematic issue. Because in the BIOS you can set preferred boot devices, and change/delete the Secure Boot settings (which most likely gives you this boot menu).

Maybe you should try using an external keyboard, as suggested here: https://superuser.com/questions/656956/i-can-t-access-the-bios-setup-using-f2-key-on-samsung-np270e5v-laptop?rq=1
