I have a work laptop with Windows 7 installed using Check Point Full Disk Encryption. The HDD was dying, so I installed a larger SSD and copied the contents of the old HDD over to it using
dd. So far so good - Windows loads correctly, and tells me it's living on a 320GB partition of a 480GB drive.
Now I thought I'd try to be clever. I wanted to try out Ubuntu on this machine as well. I already had an Ubuntu installation on a 120GB external drive, so I copied this onto the unused partition of my new drive (again using
dd). Using a Live USB image, I can see that this has worked - the files are all there. I followed the instructions here to set up GRUB2. But it boots into the GRUB 'rescue prompt' and won't let me boot into Windows or Ubuntu. I guess I've overwritten the MBR, where the encryption software resides. I can restore this from the original HDD. So how do I set up GRUB to allow me to boot (encrypted) Windows or Ubuntu?
