[newbie] HELP PLEASE - PartitionMagic error

[Sam Junge]

As I've mentioned before, I've been having problems with PartitionMagic. I installed PartitionMagic, then mandrake linux 7, then decided to delete the linux partition. No longer does my computer load lilo, or list linux as a partition, but PartitionMagic still loads as a dos program when the computer starts up and tells me "That linux partition could not be deleted. The operating system partition being deleted was not found." The only option it gives me is to click ok, which shuts down the computer and repeats the process.     I tried going to my other computer and doing a sys a:, and also putting fdisk from my other computer onto the disk. I then put this disk in the computer that wouldn't load windows, and it gave me an a prompt. I tried typing fdisk /mbr, but it didn't make a difference for the next time i booted the computer. What can I do?     Please give me a detailed enough anwser because I've tried to solve this problem numerous ways.
