Windows boots correctly, but with repulsive blinking cursor after dell logo

Hi, I have a little issue with my windows pc.

When I boot my pc, after the dell logo, I get a black screen with a blinking cursor that only lasts for a few seconds, then the windows logo appears and the boots complete. The expected behavior is mostly the same but without the repulsive and seemingly temporary blank screen and blinking cursor.

I first noticed this issue when I switched from bios to uefi (I did this with the mbr2gpt tool and toggling uefi in the bios menu). I had intended to dual boot ubuntu, and the switch was supposed to be a prerequisite. I noticed decreased performance, longer boot time, constant jetting of the cooling fan and this supposed issue. I tried to switch back to bios with the easeus partitioning tool, i.e. I converted the now gpt drive back to mbr and toggled the legacy mode on the bios menu. These resolved most of the issues, except for the temporary black and blinking cursor screen. I created a usb recovery from another pc and made a clean install of windows, but for some reason, the problem still persists.

I have searched through and almost all solutions refer to a permanent blank screen, which is not the case for me.

The thing that bothers me the most is the added boot time (up to 5 secs). I don't see myself turning my pc often if this persists, unlike before where it's mostly negligible to turn it off.

I could make a screen recording of this if it's hard to picture with words. Thanks for your time.
