Well today i faced the challenege of building a computer and swapping some parts between two. at one time i had windows and linux on one harddrive and got rid of it all with the windows boot cd to install it. well i had two hard drives now one with linux one with windows. i took the linux out(master) and put it in another computer to reformat it to windows and was reformatting the other hard drive so the MBR went on that one. Well i got it booting and set it to master. I reformatted and when it went to restart it said Error Loading Operating System. So i followed some forums and learned some stuff. i then did somethign when i was messing with it i partitioned it into 2 one that is liek 10gb for windows only and 70gb for other things. so then i rebooted and got it to say missing operating system. Need some help any suggestions will be tried. the new computer i built at 4pm i havent even turned on and its 10:30PM i really wanna fix the otehr first so please help!
