i have tried upgradeing the ram and harddrive in my desktop pc, the pc is detecting the ram. but when i first tried installing w7 on the disk in this pc it gave me a No boot disk has been detected or disk has failed. Error. So i took it to my other pc, installed w7 disk on it, just fine and thought if i put it in the gateway now, it should boot win7, but it gives me the same error. any help would be greatly appreciated. thanks.
