Issue with Boot Camp with APFS drive

I'm trying to install Windows 10 on my mid-2017 MacBook Pro and only realized the implications of the APFS in the past few days. I can't seem to find a way to work around the issue. Last time I installed Windows on a Mac was on El Capitan (Windows XP).

Boot Camp tells me I don't have enough space in my drive to partition it (Requires 40GB). I have over 700 GB free on my system (within the synthesized APFS volume). When I try to create a partition manually using Disk Utility, The system shows that I have around 600 MB unused, and won't let me touch the APFS size.

I have deleted all the Time Machine snapshots in case that was the issue and it didn't change anything. I have an active Time Machine set up but I'm scared to delete my whole drive and recover it using TM. (I expect it would revert everything to how it is now, rendering the attempt useless)

I also tried almost everything in this thread: Issue with Boot Camp with APFS drive (probably everything except deleting the drive, which was ultimately the solution in this case)

Could anyone help please? I'd really appreciate it!

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.4)

I have a Time Machine backup of my laptop. I last updated it two nights ago, but wouldn’t restoring from a Time Machine backup also bring back these errors?

The TM backup should be restored after erasing the internal drive. It will layout the filesystem after the erase, which should not have the same errors.

And my computer, I bought it in June 2017. I’m pretty sure High Sierra wasn’t out back then, right? So it probably came with Sierra.

The simplest way to check is boot into Internet Recovery and click on Reinstall macOS, without actually installing it. It will show the version original shipping version.

It is expected to produce output. Can you boot into Internet Recovery and find the APFS disk (synthesized disk) and run

fsck -f -y /dev/disk1

If you run diskutil list, what is the disk number of the APFS disk?

Sorry for taking so long, I hadn’t seen your reply. I just ran fsck. I don’t really know what it is or what it does, but I looked up how to do it. I ran “reboot” after that. Should I try partitioning again now?

Actually I realized that I probably couldn’t unmount the disk while I was using it, so I erased it through the disk utility in recovery mode. Right now my computer is installing a fresh copy of High Sierra on the erased disk. I made sure to erase the whole disk, not just Macintosh HD or the APFS container. What I don’t know now is whether I should back up from Time Machine as soon as the install is done and the Set Up asks me if I want to restore it from a Backup, or whether I should take care of something before that.
