I have 4 partitions. 160GB, 40GB each. 1 FAT32 and 3 NTFS. I have Win XP on one of the partitions - FAT32. I want to install another OS but i want it on a 10GB partition. can i resize the other partitions? and how? i know how to partition and install multiple os on it ... read it somewhere...but i have Win XP already....dont wanna loose that. I want to try another 2 OS but I want to assign like 10 GB per OS and the rest of the space as a space for storage...you know easier access to files whenever i switch between the OS. I'm trying ubuntu. Not sure if that makes a difference. Is this possible or i'll HAVE to do a clean installion??
