So new SSD drives are sexy, and now pretty good in terms of reliability. And the prices are down, too.
I use Linux Mint Rebecca 17.1 for my work machine. I had two 500g hard drives, dual booted with grub2. So this is how I swapped out my Linux drive to an SSD. Why? For games dude, why else?
I plugged in the Crucial 256g SSD drive to the system and booted into Windows 7 from the grub boot loader menu.
I installed Acronis, a drive migration and backup tool, which came with the Crucial SSD drive. I downloaded it off the web per the enclosed instructions.
I then used Acronis to copy the Linux drive to the Crucial SSD drive.
Then I shut everything down and rebooted off of a DVD (or USB drive) into a Linux Mint live distro.
Once booted, I ran Gparted and copied the UUID of the new Crucial SSD Drive.
I ran Gedit as root and edited the grub boot menu text file on the Crucial SSD Drive, replacing the UUID of the first couple menu entries with the Crucial SSD drive UUID from Gparted.
I shut down and removed the DVD, and rebooted. Your system should reboot to the boot loader menu. I then selected Linux and booted all the way into the SSD drive Mint Linux desktop.
I opened up a terminal as root and ran update-grub to finish out my grub menu updating.
I looked at using clonezilla in Linux and DD from the command line, but your partitions need to be the same size or larger on the target drive, and I am way too lazy to deal with that!
