Dell inspiron 1150

[SILO]

Hi I have recently replaced my hard drive in my dell and it's telling me No hard drive detected, and that is the same reason I had replaced it originally. Does anyone know whats wrong I know the hard drive is good and I have replaced the hard drive adapter too, any help would be GREAT!!!!!!! Thanx!

Have you gone into the bios on bootup? Is it possible you have a motherboard defect? Also make damn sure all cables are correctly connected including the power cables.

what do I do at BIOS?

You change the boot order. I think you can skip directly to the option by spamming F12 upon startup.
You can also check to see if your computer has detected the hardware in the BIOS.
