hi there.. would anyone help me out to delete my linux partition with fdisk??

Hmmm, which fdisk, because only the linux fdisk will completely remove the linux partition(s), MS fdisk will not even see the diskspace allocated for it. Simply start a linux install, whatever version, and when you get to the partition section, delete all linux partitions, then exit the install. Then get back to the MS side and fdisk will now 'see' the additional, unused space. Hope this helps, good luck.

There's also some very handy partition removal utilities available which are quick.

Technically speaking fdisk can't do it. if you want i can give you a handy tool for doing it. email me at cruxtech@rediffmail.com
