Ive just bought a MSI 745 Ultra motherboard with an AMD 1.8 and 512 DDR ram I have a Maxtor Diamond Max plus 8 (40gb) Hard drive and a G-force 4 AGP graphics card. Everything is new. I put in my startup disk and tried to boot up and load but it wont. It flashes thru the bios-- says every component is recognised but then it says "missing operating system" and wont give a prompt. Ive checked all jumpers and IDE chain configurations and read thru the motherboard and H-Drive manuals. What could be the problem? More importantly what could be the solution?
