Lost my Win 10 partition after upgrading to macOS High Sierra

Hi!


I recently upgraded to macOS High Sierra (10.13.1) on my main Macintosh partition, and since then my Windows 10 partition does not show up anymore when I press the alt-key when booting. It now only shows the Mac partition instead of both.


Unfortunately I was so stupid and didn't do a back-up before upgrading, because I never encountered any problems before.


I found some similar questions here and apparently it is due to a switch to the APFS format, but I'm not an expert and really do not understand much about these things. I urgently need my Windows 10 partition, because I have software that I need for work on it. Is there any way to get it back without a clean install, considering that I didn't do a back-up before?


This is my system:

iMac Retina 5k 27", late 2014

4 GHz Intel Core i7

32 GB 1600 MHz DDR3

1 TB SSD drive and my partition split in bootcamp was 800 GB macOS / 200 GB Win 10


I really hope that I will not lose the data on my Windows 10 partition :/


Thanks in advance for any help or suggestions!

iMac with Retina 5K display, macOS High Sierra (10.13.1)
