The OEM drive ( Toshiba HDD 1tb ) was failing, pulled it out and put in a Samsung SSD 1tb. Plugged in my Win10 Boot USB and... nothing. F9 for boot options... empty. Tried Load BIOS defaults... nothing. TPM on/off... nothing. Secure Boot on/off... nothing. I tried all of those options about 4 times, you know just to make sure, nothing worked, all I got was the No Boot Device 3FO error. So I pulled the SSD and installed Win10x64 on the SSD using a second computer, just the initial install, not all the way to the desktop. Put the SSD back in the HP Pavilion x360 - 15t-dq100 CTO and pressed the power button, this is gotta work right? NOPE, same thing, No Boot Device found, please install operating system on drive. So just for fun I did the F2 system tests and the hard drive test is OK. ( so are all the others ). AND, I can't update the BIOS because the system also refuses to see any USB drives. So here I am, stuck with the OEM drive that is so bad Windows auto recovery can't fix it, not that I really want it to, that drive has thousands of "deleting index errors", free space errors, allocation table errors. And a nice new 1tb SSD that the system refuses to acknowledge. If anybody knows an actual fix for this please let me know.

( it's a 2021 version and out of warranty )

Do you still get a 3F0 when the no drives are connected and you try to boot?
