Both my Bluetooth and Wifi adapters don't work - not in device manager

Hi everyone!

I wanted to run a separate version of Windows 10 from a USB drive, so I went and set that up.  During the process, it wiped my boot record on my primary SSD instannation of Windows.  After some trial and error (using diskpart and fixboot), I was able to get back into my primary Windows installation.

However now, my Bluetooth and Wifi adaptors dont' work.  They are completely missing from Device Manager, as if they are not installed.  I took a look around my BIOS to see if they were disabled (couldn't find anything there), I also used the HP Support Assitant to ensure all WLAN and Bluetooth drivers (and a few others) are up to date.

As far as Windows is concerned, I don't have Bluetooth or Wifi at all.  I put my phones SIM card into my laptop and am browsing using my Mobile Adaptor just to write this post.

Any ideas on what I can check?  I don't think I have a genuine hardware issue but it's possible.  I haven't moved the laptop around or anything like that, this all started when I tried to setup a separate Windows instance.

FYI it did boot into the separate Windows instance and did update the Intel XMM WWAN driver (the Mobile/Celluar/SIM based modem) drivers which I thought was weird.  Maybe it has caused an issue?  I can't see how given it's a separate Windows instance though.

Also, in my Device Manager, I have one item with an issue, an 'Other Devices' 'PCI Serial Port'.  I wonder if this is my Bluetooth/Wifi combo PCI slot or something?  No idea.  Have tried updating the driver on that with no luck, as well as running 'Scan for hardware changes' again with no luck.

I have also tried using the BIOS and HP Hardware Scanning tools with no luck.  No issues found.  Also the HP Hardware Scanner and Connection Optimizer don't seem to work at all.

Help!  I'm out of ideas!

Just for fun I decided to install Ubuntu to see if it could detect the Wifi / Bluetooth.  It said no adapters present.

Assuming the latest Ubuntu could actually detect and have drivers for the HP hardware, then I'm starting to think it's a hardware issue.

I bought a set of mini screwdrivers, think I should try opening and re-seating the card?  My laptop is under warranty but I'm in a country where HP doesn't provide support and also can't live without the laptop (need it for work).
