I have brought a Seagate 250gb external USB hard drive to make backups with. One of my computers, a Dell Dimension 2400, will not boot if the drive is connected. THis makes it impossible to backup using Norton Ghost 2003. THe drive does, however, work on another (though newer) Dimension 2400, and an Acer Aspire laptop. THe only difference between the two dimensions are that the one which the drive will not boot with has the latest BIOS, whereas the newer one doesnt, and that the newer one has recently had to have Windows reinstalled. Is there any way top get my computer to boot with the drive connected? It comes up with an error of something like "Error with booting. F1 to retry or F2 to enter setup". If i disconnect the drive and hit F1, the computer will still not boot, and i am forced to cut the power in order to boot. Is this fixable?
