I have just been given an old Dell computer and have replaced the old 20gb HDD with a 250gb HDD and added 2gb RAM. The problem I have had twice now is that I get Boot disk error, press CTRL etc. I replaced the first 250gb HDD with a new one and today the same error. The jumper settings are correct according to the seagate website. The computer boots fine with the 20gb HDD in A friend has said that my MBoard might not support a large HDD but if I got an IDE PCI Controller card that would do the trick. Anybody got any ideas or advice?
