if Disk Management can help you, then you have to try third party partition manager like partitionguru to extend system partition.
you would have to buy something like partition magic from norton it allows you to non-destructively manipulate the partitions in your computer, unlike windows own partition system that runs from the windows installer.
Data safety in the event of winders screwing up. If you have all your photos etc on a partition with windows installed on another, you can reinstall windows in the event of a serious error without losing your files.
Your question isn't exactly clear. If you want to install Ubuntu natively onto a partition, you must format the partition or make a new one. It is quite possible to resize the XP partition and make a new one without losing data on the XP partition. Ubuntu already includes the tools to do this.
Partition Magic can do it if you don't mind shelling out a few bucks. Windows can do it with convert.exe but you'll need to read the instructions at the link below.
If you have Windows you already have ntfs. Windows doesn't use ext4 at all without IFS drivers.
Use partition magic software to split the existing partition into multiple partitions without losing of affecting the data
There are several partitioning software packages available. I have used "partition magic", but that is not necessarily an endorsment, since it's an older application and I'm not sure it works on the newer drives.
Yes you can, and it is as simple as partitioning your hard drive and using partition magic and boot magic
The ability to partition hard drives can provide a range of benefits. But removing a hard drive partition can be difficult if you don't know what you are doing. With a few simple steps, this article will show you how easy it is to remove a hard drive partition without losing information or potentially damaging your drive or OS installation.
Most operating systems can only be removed by formatting the hard drive, and then installing the operating system that you desire. The drawback to this is that you will lose everything that is on that partition of the hard drive. Example : if you have a computer with Windows Vista but you want to put Windows XP on the computer you have to wipe (format) the hard drive in order to load Windows XP. This means saving all your documents to a CD or another hard drive or another partition. If you want to upgrade to a newer operating system then this can be done without losing your information, but some programs may need to be reloaded. Hope this helps. ----
If you don't mind losing all of your files then yes, it is ok.
A new hard drive generally comes without a valid partition table nor file system. Assuming you have the new hard drive cabled and configured correctly (using the jumper diagrams on the label), you then have to prepare it for a file system.The first thing you'd need to do is partition the new hard drive. Since Windows XP, Windows comes with both FDisk and a disk manager. You can use those. Once you install the partition table, you may need to format the partition(s) you created. If you use FDisk, you will certainly need to format as a separate step. FDisk is really only suitable for new drives or drives you want to completely erase, since it cannot change partition sizes once they are created without losing data.Or if you prefer, you can use a third-party partition manager. The modern partition managers can automatically do some of the necessary steps for you. So all you have to do is tell it you want a certain size partition or to use the entire space and it will make sure you have a valid partition table, that you have a FAT32 or NTFS file system, and have the correct type of partitions.One thing to keep in mind is that if you ever want to boot off of the new drive, the partition table type has to be set to Active. If the active flag is missing, any operating system that is installed on that drive will not boot. So if you can access the drive but not boot from it, then you likely forgot to configure the drive as Active. That is easy to fix and even FDisk can do that without any loss of data. Nearly every partition tool available has this option.
