Hi, just reinstalled xp. Now I wanna partition my c: drive. Can I unallocate some space on c: drive partition so that I can install linux? When I right-click on Disk0 I see "convert to dynamic disk...".

If you repartition using windows you will lose all information on your drives. The only way to partition using windows XP that I know of is to use the Windows XP installation CD. Your best bet is to get a 3rd party partitioning program such as Partition Magic. It will allow you to resize and repartition your drive without losing any of the data on it. But you should ALWAYS have a backup of any important daya as things can go wrong. And the probability of something going wrong is proportional to the amount of grief that would result in the event that there is a problem. Michael J

Some linux distributions let you resize partitions anyway. For resizing NTFS, your best bet could be Mandrake Linux. Even if you don't want to use that, you could get a cheap CD of it just to do the resizing. Much cheaper than Partition Magic.

The question danty, that hasn't been asked, is in disk manager do you have available space? In other words does the present c: occupy the entire drive or just a section of it? If there is space available then you highlite that space and create a partition. If you have no space then it means you have to resize your present c: partition. Disk manager can not resize c: so you have to buy or get a product that can. See suggestions above. Always wise to plan out your partitioning before you start installing. It avoids this and future partitioning/drive letter enumeration issues.
