I left my computer downloading all the night and I did download 35 GB of movies (legal ...). I restarted the computed in the morning then I booted in my encrypted Windows partition for my work.

I have left my computer downloading 35GB of files and when I restarted in the morning, I booted Windows. When I tried to access Ubuntu, it failed to boot and in low-graphic mode told me that it won't boot because the partition is full. I tried rescue and it reported 0 MB free.

I also cannot delete files with sudo rm as all are impossible due to a read-only file system. I can mount it in Windows but there is a "write protection" there, also.

Should I try a live USB?
