I attempted to dual boot my computer into XP and RedHAT 7.2. When I partition my hard drive, I choose the RedHAT to be on another primary partition and another logical partition for the swap files. I used PartitionMagic to do the job. When I apply the changes and my computer rebooted it started to partition it. When it was finished, it rebooted again. And an error message saying "Error loading OS," I already have XP on my computer by the way. I thought I had to install the Linux, so I inserted the cd for installation. The installation was smooth. Then I rebooted my computer. The XP wont boot only the Linux. I forgot to add Linux in my XPs boot manager. They say the MBR of the hard drive for XP was overwritten by Linux. Is that true? How can I make my XP boot again without reformatting it?
