[Q] Install a CUSTOM/STOCK ROM to sdcard - Upgrading, Modifying and Unlocking

Hello,
I just want to ask if it's possible to install a custom/stock android rom onto a sdcard? I just don't want to touch my original/stock rom and just want to test custom roms. Is it possible to boot an installed ROM from sdcard?
Thanks!

Basically it means that gain access to advanced features which usually do not have to access mainly to prevent you to break something.
1. They're basically the same thing but as its name states, with pre-rooted roms you do not have to do the rooting procedure.
2. Check 1. Custom roms are modified versions of the original rom. Rooting is the first step towards enabling you to install customized roms. This thread will help you with the installation of a custom ROM: http://forum.xda-developers.com/showthread.php?t=1016084
3. No, but be careful to install the appropriate RUU. Check this thread: http://forum.xda-developers.com/showthread.php?t=695667

1. Same thing!
2. Correct - already rooted for you. However RUU is a term relating to a stock rom, rather than a custom rom. So you just flash the custom rom, not an ruin.
3. For this you flash the ruu! You are then completely back to carrier specific, non rooted stock rom.

Which ROM is on the phone? If you want to customize the existing ROM, you may need root access.
If you want to install a custom ROM, you'll need to install TWRP in order to flash ROMs and Gapps.
