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.
Of course you need to partition your drive. If you already have installed Windows XP You need to make a new partition for win98 formated FAT32. WinXP use NTFS formatting.
When you boot from the install CD, indicate which partition you want Ubuntu installed on.
It is very easy to do this. The only thing you must remember is that you cannot install windows 98 from Windows XP environment. Either install 98 first and then XP or after installing XP reboot in DOS mode. The install will ask for the drive to install to when you do so?
If you have the windows install disc, you can insert it, restart your computer and press any key when it tells you to. This will boot from the DVD and enter the Windows Setup. From there, it will show you a list of partitions on your hard drive before you install windows. Choose the partition on which Vista is installed and click "Delete" under advanced options. The partition will be formatted. If you want to install a fresh copy of Windows Vista, you can do so now. If not, exit windows setup and install whatever OS you want to use. (Make sure you BACK UP your files before formatting - once you format the partition, you can NEVER get the files back.)
You have to create at least one more partition for Vista. If you install Vista on the partition where XP is installed Vista will delete XP. To avoid such problem you have to have one more partition. When you do that just start the Vista installation process from XP and choose just created partition for Vista.
False, it can be install on a few versions of FAT, but only up to 4GB.
It's highly recommended to install XP on NTFS partitions.
You have to delete the partition in which it is installed and create a new one to install the new vista.
If you install on the same partition where your current OS is, seven will move everything in the folder "Windows old", everything else will formatted (only on the same partition).
You must partiton your hard drive so you have two partitons(you MUST have the partition space be at LEAST the minimum requirement for the specific Operating System being installed in that partition). Once you partition your hard drive you can then install the two operating systems(one operating system per partition). Its recommended that you install the older OS before the latest OS.
Yes, you can. You will need to partition your hard drive because Linux has to be installed in a separate volume. I would install windows first and then Ubuntu.
Click the install as partition when installing Ubuntu.
