I'm attempting to install Ubuntu on my laptop to dual boot with Windows 7.
I have a single 320GB hard drive with the following breakdown:
sda1 (fat16) 41.1 MB (not sure what this one is for) sda2 (ntfs) 104.9 MB (not sure what this one is for either) sda3 (ntfs) 64.4 GB (Windows 7 is installed here) sda4 (ntfs) 220.0 GB (Separate partition where I keep photos, music, etc...) free space 35.5 GB ("unusable" ???)
I was planning to install Ubuntu on those 35.5 GB of space, but when attempting to do so it says that the space is "unusable". It won't let me format or do anything else with it.
What can I do?
