Setup my new drive with a fresh upgrade of W10 (fresh install of W7, then upgrade to W10 through windows update).
Then i found that my car diag kit doesn't work with W10. :(

I shrank the W10 partition by 40gig and installed W7 in the new space.
Then i found that my car diag kit doesn't work with W7 either. :eek:

I installed XP over the W7 install and now i can't boot to the W10 partition.

Any pointers to fix the dual boot?

Cheers.
 
You're not going to like it...

I've had this exact problem today after Win Update killed my Win 7 installation.
I had a triple-boot of Vista/Win 7/10. So I reinstalled Win 7 and let it upgrade to 10 so that I had two Win 10 installs (one is for work).

Stupidly I disconnected the drive with my existing Win 10 (as I was worried about corrupting it), and when the new install finished it hadn't written the existing Win 10 into it's boot ini.

Resetting the new install didn't work and running a windows repair didn't work.

Long story short: I had to reinstall Win 7 again. Then upgrade to Win 10 again, to let it create a new boot file from scratch (making sure that all my drives were connected).

Tl/dr: You need to reinstall Win 10 to repair your boot file, and it will detect your XP install.

Just go back to Windows 10 and install XP inside a VM such as virtualbox

Depends if the car diagnostic kit can be passed through to XP or not. Probably not. Goody idea though, it just does not work with hardware.

Assuming the car diagnostic kit is hardware of course...
 
Yeah, hardware piece, the software won't even install under 7 & 10, let alone run.

Ended up having to dump my data to a handful of USB sticks then wiping the drive and installing everything again. XP in its own partition first, then W7 in the second partition, upgraded to w10.
