Black Screen With White Dash On Boot

[OcusPocus]

Hello guys, every time i boot my PC the first thing that appears is a black screen with a white dash on the top left corner of my screen.

The PC works fine and everything, every drive is recognized by windows after boot and according to Kingston SSD Manager my SSD should be fine.

This happened recently after i did a fresh re-install of Windows 10 on my PC.

Can someone help me with this problem?

Let me be clear, i can boot into windows 10, every thing works fine, i've updated all my drivers, played games and everything with no problems, the only thing i want to know is why that screen appears, my PC used to boot a lot quicker before but now that screen is there for like 10 seconds and it's driving me crazy.

Do you have a flash drive or an external hard drive plugged into the computer?

My main drive (where windows is installed) is a 240GB SSD.
My two other drives are both from the company "Western Digital" one is 7200RPM 1TB HDD and the other one is a 5000RPM 500GB HDD, those are the only storage devices plugged into the computer. I've also tried booting with only the SSD connected (without the HDDs) and i still got the same thing.

When reinstalling windows, did you alter any boot priority settings?

When reinstalling windows, did you alter any boot priority settings?

In the BIOS, no. What i did was that i booted into my BIOS then i performed a "boot-override" straight to the USB and that sent me to the Windows installation.

Before chosing install location i formated all my drives, and then when i chose my SSD i got an error saying the disk has to be MBR, so i used the comandpromt from the flashdrive and went into "diskpart" where i chose the SSD, wrote clean, format and then converted it into MBR.

When i would later install i got an error message saying "0x80300024", so i unplugged all other disks and the installation worked.

Is the drive with the system on it, plugged into the same sata port used prior to the install?

Yes it is, all the drives are plugged in where they were before, i have not changed any SATA ports. Also in my BIOS the SSD is set as Boot priority #1.
