I have a SATA HD that I want to transfer to a new build but it's Pre-installed so do I l need to reformat prior to installing it on the new MB or make my connections first and on boot up of the new system do a reformat from retail OS MS 8? Will I run into problems or is that just the "process" because bios will ask which device I want to boot from such as DVD, it'll gain access to the disk and the next logical step would be reformatting the HD. Thanks for the help...kinda new to this.
