Ubuntu 11.04 Upgrade Overwrote My Truecrypt MBR

[user2037]

It appears the upgrade to 11.04 has overwritten my Truecrypt MBR. And since the Truecrypt partition uses system encryption Ubuntu can not even mount it.

Does Ubuntu installation or upgrade make a backup of the boot sector anywhere?

I don't think so, but it darn well ought to.

I would suggest filing a bug report or check if one exists and add your problem to it. The more that report an issue the sooner a correction may happen.

You do have to also sign up for launchpad. Many of us just use or same userID as here, but it is totally separate.

@oldfred: Good idea.
The more I think about this the more obvious it seems to me that the installer should always create a backcup copy of the MBR and maybe all 64 sectors for recovery purposes. It also seem obvious to me that the Ubuntu live CD should have a menu option to restore a standard MBR. Lots of folks would benefit.
