>>I believe you have a Windows 10 PC, so it might be much, much simpler to get yourself some recent software for drawing.<<
I could do that but I've worked with CorelDraw for many years, and learning something like LibreDraw and OpenOffice Draw to the point where I become as proficient as I am with CorelDraw would take several months. So... I've given up on loading XP on the Vista drive because it would entail downloading a lot of drivers, and only God knows what else might be packed into those drivers.
Now I'm in the process of reinstalling, or rather recovering my Vista installation.
>>Do you have a Windows XP product key?<<
I thought I did, but I'm having problems locating it right now. I do have a DVD with what I need to do a Reinstallation operation, and I used that to do a Reinstallation of Vista on the C: drive. In 2018 I also made a set of 3 DVDs that are labeled "Recovery".
I'll try those next to see if I can get an absolutely clean install of Vista.
