Boot windows from pci-e x4 addon card

[kimitza]

Hello guys.
Like the title says, i have a question.
I have received at work a lenovo m75s-1 sff pc(ryzen 3 3200G pro, 16gigs of ram, 500Gb HDD). I have a m.2 sata 3 ssd, which i want to add. I bought a digitus m.2 ngff / nvme ssd pci express 3.0 (x4) add-on card , but i found out later the custom lenovo motherboard doesn't have a pci-e X4 slot, just a regular pci express, 2 pci-e x1 and 1 x16 port. I inserted the adapter in the x16 slot, all is ok, windows detects it, but can i make it bootable?
To answer further questions, i can't replace the HDD that came with, i can't add a regular nvme(due to aquisition restrictions). All i have is the m.2 sata ssd.
Thank you

As long as the board itself allows booting off PCI, it'll be fine.

There is no "PCI booting" involved anywhere here.

With that adapter, M.2 SATA SSD uses SATA cable to connect to motherboard's SATA controller.
There is nothing special to be supported or enabled. Treat it like any other conventional drive.

That depends on which slot was installed. The top is indeed SATA and can be treated like any conventional SATA drive. The bottom slot is wired for PCI-E and the motherboard needs to support booting from a PCI card to boot off that drive.

I plugged the card in the pci x16 grahics slot. Windows sees it as a smi disk drive. Now i'm trying a fresh install, because the previous migration did not worked. I mean, the migration was succesfull, but when i removed the old hdd, i got a bsod on boot. Maybe because it's an oem system? I saw the license encoded into the bios?

Clean install is best install.
