So i have a server on OVH with CentOS5. One of the HDD was failing so we had to replace it.

We did the RAID resynchronisation (RAID-1) but then the server can't boot. The error is "select proper booting device and reboot"

We have tried a couple of things but nothing solved the problem (see here = http://www.webhostingtalk.com/showthread.php?t=1367341)

We're currently in Rescue Mode and we are still looking for a solution. Formatting and starting over isn't an option.

We are willing to pay if someone wants to login into our server and solve the problem for us, unless you are some untrustworth user with low posts.

seems to me like a bios problem, or you just need to repair MBR..

Problem is that we don't have access to BIOS, this is a remote server hosted by OVH. We only have access to the rescue mode right now.

How do we repair the MBR ?

this will help?
