I recently swapped out my Maxtor 80GB Master and 60GB Slave harddrive for a Western Digital 250GB harddrive. When I boot I get the Disk Boot Error. My boot order is CD-ROM -> HDD 0 -> HDD 1. I have a CD-ROM/RW and DVD-ROM/RW and they are cabled and mastered/slaved properly. I'm trying to install Windows XP on this new HDD, but I can't get to anything in windows, such as partioning, etc. I believe it is a hardware issue but I'm not sure. I tried resetting the battery on my Mobo, switching in and out different peripherals but nothing is working. I know the CD-ROM and DVD-ROM are working as the CD is still spinning when I open them. I took out the slave drive just so I can see if I can get by all this to install windows to the big drive and just add the other one later, but I'm still having the problem. The only problems I can see happening are: 1.) Bad cables 2.) Bad Mobo 3.) Bad CDROM 4.) Bad Disk Any help would be much appreciated.
