Error: no boot disk detected or disk failed
Keep getting this error on my sx2110 even after replacing hard drive.
Welcome to the community, Help1949!
I'd recommend you to check the connections to the newly installed HDD. I'd even swap the SATA cable with a different one and see if the error will proceed. Check the Molex cable as well (the one connecting the HDD to the PSU).
Another thing you could try is resetting BIOS by re-seating the CMOS battery on your motherboard. Here's a tutorial with several methods to do that: http://www.wikihow.com/Reset-Your-BIOS
Keep in mind that this procedure will get your BIOS settings back to factory defaults, though, so you'd need to know how to re-configure them afterwards.
Keep me posted. Hope this helps you!
