Hi i have a Western Digital Caviar 500G 7200rpm HDD(16Mb Cache) and intend to divide it up to 3 or 4 partitions and put a different OS on each partition using GRUB2. However somebody said that a single hard might not be able to have that many partitions that a computer can boot from. Can anybody please tell me if I can have up to 4 bootable partitions using grub? much appreciated
