You cannot install Windows XP on the system without a ground-up rebuild (XP will not work with a UEFI boot/GPT disc). Since XP goes completely end of life on April 9, 2014 (no more security updates), forget it - the OS is history.
Whether you can install Linux depends on finding a distro that supports EFI and GPT. A few do.
Before even attempting to install Linux, MAKE A BACKUP recovery USB drive (you'll need a minimum 16G flash drive to do so).
I need a clarification, whether all these partition are backed up or only factory backup is done, when recovery back up is created ???
And secondly, If I wish to reinstall windows 8 besides Linux, what are the steps to follow. And will these partitions (EFI, OEM, Recovery partitions) are automatically created or wiped out if formatted ???
