Windows 7 installation error

[AliAsif1]

Hi guyz as i try to install windows 7 it gives me an error saying "Setup was unable to use the existing system partition because it does not contain the required free space."
I tried installing from a bootable disc and also from the HDD but it gave me the same error and i also tried isntalling two different versions of W7 but the same error
I want to dual boot Xp and windows 7 it allows me to updrage but i want to dual boot
It gives me the same error while installing on any "Partition" i,ve like more than 100 GB space on every drive
Plz help if anybody can

You have a mess there. It would be better to start over with all of your data backed up, then boot the installer to delete all partitions and create new as you wish before Clean Reinstall - Factory OEM Windows 7
which steps are the same for retail.

XP is expired so I'd leave it behind or virtualize it in Win7. If you must have it then install it first so that Win7 will configure the Dual Boot when installed second. Dual Boot Installation with Windows 7 and XP
