Question Windows 10 not sending signal to monitor when booting from SSD, but works flawlessly with HDD

[Srksi]

Long story in shortest: If I boot from SSD system will start fine, but I wont get any signal to monitor.
If I pick windows SSD instance from dual boot with HDD as boot device, system will load fine.
It all started when I wanted to install windows on my new SSD. Deleted old windows install on HDD, did proper install on ssd, but first second I set SSD as primary boot device, I dont get ANY monitor signal while system works fine in background. Found that way later after few hours when I gave up on installing windows to my ssd and went back to my hard drive, saw it actually created dual boot. Tried using integrated card just in case, but still same, its not case

What I usually do when I need reinstall the OS onto an SSD while the existing OS install is on an HDD, I tend to backup all mission critical data off the HDD, format the partition with the OS and relevant OS partitions using a bootable USB installer. Then I disconnect the HDD from the system, then install the OS with only the SSD hooked to the system.

Tnx, that option do passed through my mind few times, will try it when I calm and fix few even worse problems, but still, with my luck that wont be just boot clash, Im expert in attracting unsolvable problems... 🙁
