Hi
Hoping can get some help. Have Dell Precision T5810 that have upgraded ram and graphics for my son to game on.

Intel® Xeon® Processor E5-1603 v3 (4C, 2.8GHz, 10M, 140W).
upgraded 32G ram
500GB 3.5" Serial-ATA (7,200 RPM) Hard Drive
upgraded graphics card
addition: Samsung 750 256 SSD

On Sunday my son attempted to add a new 1TB Sata in 3rd slot, in process removed the existing Hard Drive and SSD and reinstalled. the system would not boot up. So i removed the new drive and reinstalled the original drives.

Now the Windows 7 Operating System will not load as neither the HDD or SSD drives is recognized to Boot. In fact I cannot access the drives.

This is where it gets confusing. All my attempts to boot from drives have failed - because system keeps saying that no hard drives are present. However the BIOS is showing the drives, HDD 0-0-0 and HDD 0-0-1 and the onboard Dell EPSA system tests show drives with no errors displayed.

I just spent an entire day on this - research on the site suggests using CMD. When I tried to use Windows 7 OS as boot disk the commands DISK or bootrec.exe the disks are not found.

So basically I have no operating system, no way to access disks so need some assistance.

Assuming the SSD is the boot disk, have you tried booting the system with only the SSD connected in the system, i.e., no other drives present at the time? Still no boot?

If so...since you obviously have a working PC, any chance of (preferably) internally-connecting the SSD as a secondary drive in your system and using Samsung's Magician program to test the health of the SSD? Or connecting the SSD as a USB external drive and testing it via that connection?
