Hello, this is the problem of MSI 6728 motherboard; it can't boot from CD CODE 5. What does that mean? but if i will use win XP, it can boot., but in win 7 OS, it can't.
Unfortunatly Microsoft have decided that they want people to start upgrading there PC's more the MSI MS-6728 is aparently obsolete but...
There is a way to get win7 to run on a MSI MS-6728 as I had the same problem, if you have a copy of vista to had you need to take the boot file and add it to the win7 cd and burn win7 with the vista boot up and it will work if you need any help I have it on a DVD and can send you a copy if you want, as it is quite a farse to do it
