I have installed win10 on ssd. When i want to turn power on, it happens all the time, red led is solid on, but the green led is flashing four time. I don’t have signal on my monitor, doesn’t want to boot up. Please, if somebody can help… thanks. I have Raspberry pi4B.

Probably a corrupter or incomplete image on the SD card.
I’d reinstall it, also you should consider joining the discord or telegram since this forum isn’t really used
