Our PowerEdge server recently crashed. It had Raid 1 configured. The error message is "Operating System not found". I tried booting it from second disk, same error message. I contacted Dell technical support. They confirmed that issue is OS related and couldn't assist. I have two choices. Contact MIcrosoft technical support to repair my OS or reinstall Windows SBS 2008 and recover OS and Data from most recent Symantec Backup Exec 2010 backup. If I reinstall Windows SBS 2008, Symantec Backup Exec 2010 and recover from backup, will everything work the way it used to? Please get back to me ASAP, it's urgent. Any help would be appreciated.
