How do I reinstall grub, after I have reinstalled Windows XP on dual boot system?

I have Ubuntu 14.10 installed, and I'm trying to reinstall grub from Ubuntu 10.04 Live CD. However, I cannot install boot-repair (E: Couldn't find package boot-repair) and I have no idea what "main partition" refers to here. Is it the partition I have Ubuntu 14.10 installed on (/dev/sda2) or the one with Windows (/dev/sda1)?

Solution: The problem was that I was using Ubuntu 10.04 Live CD. boot-repair installed right away from Ubuntu 14.10 Live USB and it solved the problem.

The 'main partition' referred in this answer is the partition on which your Ubuntu is installed. It is the one you mount as file system root (/ directory) when you boot Ubuntu normally. So yes, in your case it would be /dev/sda2.

Your other option was to use boot repair instead of manually reinstalling GRUB. Probably you forgot to install the PPA (sudo add-apt-repository ppa:yannubuntu/boot-repair) or to update your software index list afterwards (sudo apt-get update). Note that you need a working internet connection for this. Otherwise you would have to download it as .deb-file and install it manually with sudo dpkg -i /path/to/file.deb.

But anyway, you should use a newer version of Ubuntu as live system. 10.04 is now 5 years old and hits end-of-life in April 2015. Better use 14.04 LTS (from April 2014, 5 years support) or 14.10 (from October 2014, 9 months support). The next release will be 15.04 (in April 2015, 9 months support).
