Hard Drive Not found - dell Optiplex GX260

[afischman.]

I got a Dell GX 260 without OS. I removed the hard-drive from my old system and set it to master and set the jumpers on the new system to slave and daisy-chained the hard drives into the new system. On boot however, I get the error PXE-E51 and PXE-M0F. I have entered BIOS to reset the hardware but there is no way that I can see to change the specs on the two hard drives.

Granted I'm reaching back several years since the last time I did so much hardware manipulation (it felt good!) but I am at a loss trying to figure out how to have the new computer boot, preferably off the drive from the old computer

The bios should at least detect the drive.

Try one drive at a time first. Some drives have a separate "Master with slave" jumper setting.

Is there a reason you aren't using cable select?

GX260s are a known model with bad caps, so check that first.

Also, the new computer isn't likely to boot properly using the OS on the old system's drive. You would need to do a Repair Install for that to work. At least try booting into Safe Mode if you do get it to detect the drive, and make sure to back up any important files first.
