Right. So I got a virus on my Windows -> booted up on my Windows XP install disk to format the partition -> the CD told me to delete the partition first, which went WRONG and I deleted the whole thing I guess. Sigh. So now I have only the Windows part, which I found out when I realized my new Windows was 200 Gigs bigger than before. I know that I can't actually fetch the lost Mac partition back but how do I install the Mac OSX back into my computer? Is that possible? And also, if it is possible, would it run the same way as it did before, because now the partition process is the other way around (windows is the main partition and Mac is the one being installed later)? A reply would be so very appreciated. Thank you.
