MacBook – Installing Windows 10 on Early 2011 MacBook Pro (VirtualBox method)

Apologies if the etiquette of posting is incorrect, I'm brand new to the site despite lurking for years and couldn't seem to comment on the guide I mention below.

I've been trying to set up Win10 on my Early 2011 MBP, using various methods and receiving even more error messages/setbacks.

As an intro to the problem, I'm trying to use a method that doesn't involve using my internal Superdrive as I've discovered it's seemingly broken over the years and so it's unusable. Now this causes me Legacy/EFI problems I'm learning, to install via USB that is, even after fixing my MBR/GPT partition tables Windows will cancel after the install. I've tried to bypass by following this guide: No bootable device USB 2.0 MacBook Pro mid 2014

I've tried the above guide multiple times and have come across varying factors in the guide.

The most common one I'm facing (and my current problem), is when it comes to listing the volumes in diskpart – the FAT32 32GB partition titled BOOTCAMP I've set aside for Windows isn't listed in the volumes. This isn't always the case, sometimes it's shown – sometimes it isn't.

The only variable I can think of as to why it now won't show is because I've switched Windows 10 ISOs.

The reason I did this is because yesterday the install process probably went the furthest it did. All the files managed to xcopy to the virtual drive, then back onto the C drive – and even showed in the Mac boot screen (which occasionally doesn't happen) – but upon loading the screen instantly went blue and said there was a problem with my boot files and Windows needed to repair.

So I downloaded the newest .ISO from Microsoft yesterday. But now, as a result, the BOOTCAMP partition I've set aside never seems to show up in diskpart.

This has probably been the bane of my existence for the past 2-3 days – so any help is massively appreciated. Thanks.
