I was thinking of :
100gb - windows 7
50- ubuntu
150
200
200
300
the last four for games, movies, music etc.,
No harm in doing so.
Have as many partitions as you want.
Better make the partitions using an xp cd
or else when u make the 5th partition during insallation it doesnt allow you.
and when you make the partition in disk management......all the disks would be converted to dynamic disks.........oh GOD why.
You can do so by using any partition tool.
Just after making 3 primary drives, do not create a primary drive but create a extended partition and then as many partitions as you want as logical partitions in the extended partition. This is called logical partition I suppose. Thats what the XP parition manager does after you create the first partition.
Primary partiton only good for OS or we can use for storing data too ?
Suppose 1TB HDD.
60GB Primary for Win7 OS.
900GB (Primary or Extended/Logical ?) for data.
And rest for ubuntu.
