boot system(Windows 7) via USB3.0 connector

I have a USB flash drive on which the Windows. By connecting it to a PC and putting the BIOS to boot from this USB drive, I boot into Windows.
Now the question.
Is there a PCI or PCI-e Adapter with USB3.0 connector ,to be able boot system(Windows 7) from an external hard drive(or USB flash drive)?

Hi W1nn1e-

Thanks for posting with your question!

We do have a USB 3.0 PCIe card for PC’s with an available PCIe 1x “short” slot:…

As you know, the ability to boot from a USB device is a BIOS question, so whether the system is able to boot from this card may vary with BIOS support on the motherboard.

I hope this helps, please let me know if you’ve any other questions.

Best wishes-

You have not answered - the BIOS to detect my USB flash drive or not (through this adapter)?

Hi - most system BIOS will only recognize USB host controllers that are built in to the motherboard. They will not recognize USB host controllers plugged in VIA PCI.

So unless you have specific, different information from your motherboard maker, please assume it *will not* work.

Sorry for the bad news, but hope that helps avoid frustration. Thanks for asking ahead!
