Thanks for the suggestion.
I don't think the partition is mounted, but maybe you can help me debug.
I've attached the contents of /etc/mtab, and I don't see the Windows partition in here, and there's also nothing in /mnt/.
However, there is a weird line in /etc/mtab:
vmware-vmblock /run/vmblock-fuse fuse.vmware-vmblock rw,nosuid,nodev,default_permissions,allow_other 0 0
Do you know what this is? Can you tell if the Windows partition is mounted in some way I missed?
Thanks!
