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.
