Purchased a WD Blue 500GB for Acer Aspire 4720Z laptop. Original HDD is 120GB. OS is Windows Vista. RAM is 2GB DDR2. Has a dual core processor. Would like to update to Windows 7. Hoping RAM is okay as is. Need help to install.
Am I to replace the original HDD or is there room enough for both? If I must take out the original, how do I save everything before doing that? And then, how do I transfer everything to the new HDD?
Also, how will the dual core processor be affected when upgrading the HDD? Must I format the new HDD in a special way?
And lastly, when I do install the new HDD, can I upgrade to Windows 7 without having to reinstall Windows Vista?
Thanks so kindly for any help!
