Hey guys,

I am having some trouble with GRUB. My system is a custom built unit with an msi 7093 motherboard, 1gb ram and two internal hdd, 80 and 100 gb. Since i recieved the 80gb hdd i installed ubuntu on it and ran it alongside windows xp before and currently windows 7. I had decided that i needed extra space and that ubuntu was gonna go. I pulled out my trusty ubuntu cd and popped it in. i proceeded to go along with an installation. once I got to formatting and patitioning the hdd, i formatted the linux drive and made it fat32 and quit the intallation. I went to reload and grub gave me a error #15 or 17 dont remember for sure. i reloaded a few times and it changed to 21. I have tryed booting the windows cd but i keep on getting the grub error before it even loads up. I had tried reinstalling ubuntu to get grub there again but it doesnt recognise the fresh installation so i am forced to runn off of the live cd. How can I get the error to go away so i can get back to the windows boot loader?
