I have a 1 TB HDD with seven partitions, one ~600GB for Windows and one ~300GB for Xubuntu and a bunch of assorted system partitions taking the rest of the space. I recently overwrote my Xubuntu partition with a fresh install since I messed it up somehow, and this is where my problem starts. Before, GRUB would show up at boot asking me to boot into either Xubuntu or Windows. After the reinstall this does not happen anymore.
I've tried running
os-prober, but it just does nothing and outputs nothing.
update-grub shows my Linux partitions alright but doesn't mention Windows at all.
Here's my layout (

EDIT: I can mount my Windows partition and view the contents no problem.
