That's OK i will try coming weekend but if I restore from a time machine back up can I do that only on the 85 GB partition? When I was trying to do a fresh Yosemite installation it was asking me to do it on the 35 GB windows volume. It can't see the Mac volume anymore. Further would a restore with a backup previous to the fix I did last week to enable the Windows partition not disrupt again windows?
