The Ubuntu dial boot tutorial says:
a GRUB boot partition 100 Mb -- formatted to filesystem type ext3
a logical partition for the / (root) folder of each planned Linux (or Mac) OS (at least 10 Gb each, but 20-50 Gb is better) -- formatted as ext3 (or ext4 if you are planning to use a newer Linux OS)
But how to format ext3
type? Windows XP doesn't offer this type. Only FAT32.
ext3
orext4
file systems so you can't format from Windows. However the installer can create the partitions it needs see Dual boot windows XP and Ubuntu 12.04 as suggested by Radu. – Warren Hill Jun 26 '13 at 14:14
