I have a HP ML370 G4 (Yes I know she's old) that is (was) running SBS 2003 R2 Server that has a 'no-operating system' error on start up. I would dump the server but unfortunately, it is running a custom database that is very important to us and that I need urgently to get back up and running. The system was running reliably and Barr a couple of hard drive swaps over the years she has always rebuilt herself and been faithful. I do have it connected to a WAN as we have XAMP Apache running on it in conjunction with a customised mysql database that acts as a web server for informational access to our organisation internally. All was well until one morning I walked into our server room and on the console of this server read 'no-operating system' and the obvious loop of rebooting itself. I have boot into the HP smart start 7.7ver CD and all is well with the hardware, disk array controller, batteries, drives and the actual raid array and logical drives all intact but it does report that there is no operating system! I don't know what has happened but I do have a suspicion that because the server was on the WAN that I may have been hacked or the obvious that windows server 2003 has crapped itself. I do have a backup although it's not up to date and as a last resort will use that to get it back up. But I'm hoping to get the system up again as there was some critical data that I needed that was inputed into the mysql database just after the last backup.
Please help as I am stuck and have not done or touched anything in the event that I may destroy or ruin any possible chance of recovery.
