I have a 320GB HDD on my laptop. It has two partitions C:, which has windows 7 installed on it and D:, which is free to use. Both have 150GB total space. I used windows disk management to make another partition out of D. I am in the wizard now and have been asked what file system type to use for the new volume, exFAT or NTFS? Which is ok to use for Ubuntu? I have been using wubi for a while and want to have a proper installation of Ubuntu alongside windows.
