A couple days ago my computer
was running (a friend was playing Dragon Age) when the power on my block suddenly went out due to a storm. Upon starting up my computer after power was restored, I kept on getting the "missing operating system" error.
Some things to note about my computer: The OS is currently running on a RAID 0 array of two 250GB Western Digital Caviar SE16 WD2500KS hard drives. Normally when I boot, I can see the nVidia raid utility to check the status of the RAID stripe. With this "missing operating system" error, it simply skips that raid utility which leads me to believe that there is something affecting the RAID setup.
Now before I try replacing the MBR/partition table as suggested on the Faultwire site, I wanted to know if anyone can offer some solutions or suggestions that I can try before attempting to do this. I was kinda dumb and didn't backup
for the past month or so, so I'd like to see if I can get past this issue without having to format the HDs.
In that case of it not doing the check, go into the BIOS and see if the RAID is simply off. If it is, just turn it back on and set it up how it was before. When it boots it should read the drives and find the config. Tell me what happens.
