upgrading from 32-bit to 64-bit
good day, im planning to upgrade my windows 7 32-bit to a 64-bit OS.
how can i do it by not losing all my files in hard disk, by not using a external hard drive or burning all my files in a dvd.
my hard drive is 500gb. installed items are 200gb so i have extra 300gb free.
is it safe to have a partition in my hard drive without losing all its data.
thank you in advance....
