cant allocate unallocated 243GB HD disk space

Specs: Windows XP
I am currently having problems allocating my unallocated space to my hard drive. I currently have a C: drive with 12.55 GB capacity and a D: drive as another partition. There are two other partitions Grub being the bootloader for linux and then the linux partition. The next area it shows that there is 243.61 GB of unallocated space that I cant seem to make a new partition or assign a drive letter. Ive been trying a lot of different methods, but no success at this point. If anyone could help me solve this issue it would be greatly appreciated!

I assume, the 4 already existing partitions are all of type primary.
That's a problem, because the MBR (Master Boot Record) can only have 4 partition entries.
To add more partitions, one of these 4 partitions must be of the type "Extended Partition".
In an extended partition, you can create other logical partitions, at maximum 24 logical partitions.

So you have to delete one of the primary partitions and then create an extended partition, where you can add additional partitions you need.

But keep in mind, when deleting a partition, all data on this partition is lost.
So you need to backup or image this partition before deleting it.

The original poster should always write the last response !!!
Let us know, if the problem is solved !!!

You might want to post the disk size and the size of each partition so we are sure of what you are saying.

Also, space can only be moved from or to adjacent partitions.
