How to replace root ebs volume with another root ebs volume? [closed]

Question

I accidentally formatted my system and the access keys to the ec2 volume were also deleted. So I stopped the instance and detached the ebs volume.
However I am not able to attach it to another ec2 instance as root(/dev/sda1). Can anyone please guide me through it? All my data and server files are there in the volume.
I mounted the first ebs volume and on the 2nd instance and browsed the files in there. They are all intact. If it cannot be mounted on as root volume, I need a way to get all the mysql data from the volume as there are a number of wordpress websites hosted on it. I can access the wordpress files but I dont know how to get the database from the instance.
Any of the solutions will save my life... Thank you very much

Answer 1

What you need to do:

1. Stop the instance
2. Detach the current root EBS
3. Attach you new EBS under /dev/sda1 (for Linux) and /dev/xvda (for Windows)
4. Start your instance

Technically that's it. In case of problems, you can always attach the EBS as non-rooted EBS (such as /dev/sdb) and browse the files and fix the error if possible.
