I see you figured out part of the solution on your own. Good going! You can skip the first paragraph and go directly to reinstalling Grub.
The reason you can't claim the 110 GB freed up by deleting sda2 is that you are working from the LMDE partition. That means this partition is mounted and Gparted will not work on a mounted partition. Sorry, I forgot that when I was writing the procedure for you. To claim that 110 GB, you must boot from the install CD and run Gparted from the live desktop. That will let you unmount sda1 and resize it.
You installed Mint 10 after LMDE so Mint 10 rewrote Grub to look to Mint 10 on sda6 for boot instructions. You will have to reinstall grub using the live CD.
To reinstall grub, try the procedure here
You already know the partition you are using, sda1, so you do not need to do the first step of running fdisk -l to find it.
The next step is to enter in terminal "sudo mount /dev/sda1 /mnt" (without the quotes)
Next run "sudo grub-install -- root-directory=/mnt/ /dev/sda" (no quotes)
Remember you are running from the live CD so there will be no request for a password.
Once the last command has run and the terminal has returned to the prompt, Close the terminal and shutdown the live CD session.
After removing the CD and letting the computer turn off, reboot. If everything worked, you should boot into LMDE. Once there, open a terminal and enter "sudo update-grub" just to make sure grub is properly set.
Followed your instructions with Julia live CD and when rebooting I get the same grub rescue error.
