Multi-boot system, High Sierra upgrade stuck on filevault2 step, suspect Clover update issue.

TL/DR: Is there a way to update Clover from Windows 10 on a multi-boot system? (Forgive the formatting, not on mobile, just can't use the editor.)

I have a multi-boot system with Win 10. Two months ago, I decided to upgrade from Sierra to High Sierra. Before I did that, I decided it might be a good idea to upgrade Clover. Oops! My High Sierra upgrade is now stuck on the FileVault2 step. I've tried 'rescue' mode, but I can only restart the High Sierra upgrade from there. Time Machine won't let me go back to a working Sierra system. However, I can still boot into Windows 10. After a lot of googling, I learned of an problem where the clover updater would fail to install the correct drivers. The only solution I can find is to download the Clover ISO, unzip it and manually copy that file system into the UEFI/EFI file system. There _HAS_ to be a better way. Does anyone have any suggestions besides rebuilding the entire system from scratch and losing everything?

Thank you
