Boot option problem - P8P67

[IlNerdChuck]

Hi, so in the past few weeks I had issues with windows on my P8P67, the problem was that sometimes the windows boot manager will currupt itself, forcing me to reinstall all. After 3 or 4 times I decided to throw windows and switch to pop os. I erased everything in my ssd an installed it. After like 5 days on startup a boot error appeared, "your windows boot/etc.. seems corrupted please insert a media to try the repair", I was really confused by a windows message on a Linux machine. So i started do diagnosis the problem:

1. I erased all partition in the ssd and HDD

2. Checked the boot options with attached only the keyboard (not even the mouse), and here I found something strange, I have 3 boot option, my ssd, HDD, and a generic storage usb, but I had nothing plugged in.

3 I unplugged the ssd and hhd, and it still appears like in the photo

4 I tried resetting the bios, nothing it is still there

 

So I don't know what it is, can it case the bootloader corrupting? I think maybe?(is a virus?), At this point I only want to discover what it is.

 

Upgraded to latest bios my P8P67, 

CPU 2600K

32 GB Vengeance

Nvidia GTX 970

750 cooler master PSu

240gb ssd

2tb hdd

You must have a USB drive, accessory, card reader or such connected...

Nothing, now that I think the only extra is the front usb, can they be? I try unplugging them after

Well yes if there's something plugged in them, or if the case includes a card reader connected there

Ok i unplugged the front usb and it has gone thanks didn't thought that a front usb(with nothing plugged) was recognized as a usb device
