It's a HP250 G5, I set it up myself and seem to have ended up with Windows 7 instead of 10- I really don't get on with 10 but everybody tells me that it's the future and that I should bite the bullet and go for 10. Fuck. 
At the moment busy following the installation leaflet and as suggested have backed up my personal files (the only ones I can think of are a couple of thousand photos I downloaded off an SD card, I should have deleted them all if I had known that it was going to take so long-a couple of hours- that can't be right, two whole effing hours??) The instructions were available in the Win 7: Select>Start>HP>Help and Support>User Guides
At last the screen says it's all backed up.
Anyway, worry #1 is that a few minutes ago I noticed a suggestion in the first paragraph (how could I have missed that?) that "to take full advantage of the Win 10 features I should have enabled UEFI: Unified Extensible Firmware Interface Native Boot mode in the BIOS settings before installing Win 10.
* Am I too late to do so?
* Would it be better if I started again and did so even though I've backed up already?
The next hurdle is where it says to insert the Windows 10 operating system media into the the available optical drive (that would be the DVD drawer, right?) Well, I have two DVDs: Application and Driver Recovery DVD, and the other: oh, there are two in this envelope actually, they are System Recovery DVD, dics 1 & 2.
* Do I go for the Application and Recovery DVD? Or perhaps one or both of the other two discs?
Look, I'm trying hard not to feel stupid here, but if I don't know then I don't know, right? I feel sick.
