Hi there. I am reviving an old Dell Dimension 2400. Right now I am using a 40GB HD, which works fine. But one of the HD I put in is a challenge. I can store information on it, but it cannot boot. It's a Maxtor PATA 200 GB. So far I have installed a Windows OS; files are copied, but then the disk can't boot. I checked, the files are there. I repaired the startup. Still no boot. I tried that several times, even deleting the partition, reformatting. So I decided to install a Linux system. Same story. All the files are on it, but it just will not boot. It hangs after the Bios turns over to the OS, then after a while the BIOS returns a message 'retry boot' or 'system setup'. The 200GB was hooked up the same way, as master. If this happened just in Windows, I'd understand. But also Linux. Weird... Any ideas? Thanks in advance.
