Can a PC show more ways to boot than actually exist?

1

I was running Windows 10 along with a small partition for Ubuntu on my Acer Aspire (V Nitro) VN7-592G with a Crucial SSD and a Toshiba HDD.

I didn't use this partition and erased it some time ago, I had still the option to boot to ''ubuntu'' in the F12 menu of my pc.

Today I installed Manjaro on the whole drive, creating a new partition table and all first, but the Ubuntu option is still there.

I even tried deleting it following How do I remove unneccessary boot device options? but it still shows.

How is that possible and how can I delete it?

If I get this correctly, you are trying to clean your hard drive completely? If yes, the simplest way is to use Diskpart. Do you have only a single drive? – Natsu Kage – 2020-01-30T19:31:27.413

1I have 2, I disconnected the second and the ubuntu tag shows, I swapped the drives with a blank one (no operating system installed on this second drive) and this tag still shows (even though ubuntu has never touched this drive). – user605734 MBS – 2020-01-30T19:38:01.223

Try using bootice: https://bootice.en.lo4d.com/windows This means reinstallation w10 though.

2What do you see with sudo efibootmgr? – lx07 – 2020-01-30T20:07:12.213

1when I execute sudo efibootmgr a list with the manjaro installation, ubuntu ¿?, and cd and usb boot options.

When I delete it and run the command again it doesn't show until I restart. – user605734 MBS – 2020-01-30T20:35:51.890

Yes, it is possible.

For example, I just installed CentOS 8 on a server using UEFI partitioning, then reformatted the drive to erase the OS. Despite that, that machine's boot menu still shows CentOS 8 .

The method to delete it depends on the BIOS options of your PC, which are accessed by pressing F2 during or shortly after the Power On Self Test ('POST'). Page 38 of your manual (linked in your question) suggests you select Boot from the categories listed on the left of the screen. Try deleting excess items from the list of OS to boot from listed there.
