You will need to give more information than that if you want help. Which system is working, which system is not working?

Now, there is an raspbian system in my pi. In fact I want to install a system writen by my group, so I just try to install another system, which one is ok, I chose OpenELEC. I download an img file, then write this img into an SD card by Win32DiskImager。 But when I inserted the card, the Pi showed nothing but the red light. I want to know why.... Or what would you do if you want to install another system?
My English is not so good, I wish you could understand what I have said....
Thank you very much !!!!

Maybe there is a problem with the SD card you used? Or the download was corrupt? You rememberd to unzip the download to it's .img file state?

If pi already have a system and I download a correct .img file and SD card is fine, I insert the card into the pi, it should boot from another system?

Yes, no information is stored on the Pi, all of the information is stored on the SD card, new card = new system, systems changeable by swapping cards (with power OFF).

Which format should my SD card be? FAT32 is ok?
Because I have use SDFormatter to format my SD card. Maybe it is the problem?

The SDCard (8GB minimum size) starts with a single VFAT partition that uses all the available space. That's precisely what you get when it is reformatted with the SDCard Assoc. formatter program.

If you write NOOBS to it you simply unzip the contents of the *.zip file directly to the root directory on the card. As soon as the RPi boots it will reformat the card into (at least three partitions (two primary & one extended)). Partion1 - 59MB VFAT, partion 2 - extended, partition 3 - 62MB ext4, partition 5 (in partition 2) - 59MB VFAT and partition 6 - ext4 (using rest of the available space). The layout is slightly different if you install more that one operating system.

If you use Win32DiskImager to write a disk image to the card you'll (normally) get two primary partitions. Partition 1 - 59MB VFAT and partition 2 - 4GB ext4 root filesystem. The rest of the space is unassigned until you use raspi-config to extend the root filesystem to use the remaining space.
