My Current OS is MS Windows Vista Ultimate 32bit(c: drive) and I now want to install Win Xp (d: drive) on my PC. I am afraid that If I install XP now Vista wills stop booting and installing vista and Vista SP1 takes a lot of time and I don't want to install it again. PLZ any one help me installing XP coz is dont want to currupt my system again. Also tell me if will b able to install Linux SuSE found on Aug 2008 digit dvd without currupting my system.
