Several years ago I purchased a rather nice second-hand computer. This one I did not build, put together, or install (system specs are below). Somehow the boot manager became corrupted, and I cannot fix the error. I can go into further details when needed, but it seems that one of--if not the main--issue is a lost RAID 0 configuration.

The original drives were C, D, and E. D and E drives are 500GB HDDs, while C was two 250GB SSDs in a RAID 0 configuration. Earlier this year I added a Samsung SSD 970 EVO Plus NVMe M.2, using a Sabrent NVMe M.2 SSD to PCIe X16/X8/X4 card with an aluminum heat sink to the PCIe X16-2, which became drive F.

When I try and repair the bootup, it seems as if the two 250GB SSDs in the RAID 0 configuration are being seen as two separate drives, and therefore the repair software can't find the OS because that now is located on a drive no longer identified as C.

Is it possible to reconnect those two drives back together as RAID o without losing the data there? I think that should I be able to do that, then I can get the boot manager reconstructed again.

Happened to me years ago with a raid 0+1 (raid 10) array in a 2 disks in raid 0 + 2 additional disks in raid 0 as a mirror. The benefit of raid 10 is that you theoretically can lose up to any 2 disks simultaneously and after replacing the bad disk/s rebuild the array. I expected this would allow me to forgo offline backups...what a huge mistake it was. In my case the raid controller had gone haywire and corrupted the entire array (see the disks were fine...mechanically). I sent the disks to a recovery service that gave me an estimate of $20,000.00 with the stipulation that the largest contiguous chunks of data were 32k. 3 years of photos (think family, as in photos of my young children) GONE...3 years of pics of my kids that I could NEVER replace.

Certainly you can attempt to re-establish the raid, however, I would almost bet it will require a format.

All I can say is I hope you have a recent system image, because it is HIGHLY unlikely you will recover your array. Losing irreplaceable pictures of my kids taught me the importance of offline backups.

Well, any luck?
