I have a dell xps8500 which origionally had windows 7. As of june 2020, i UPGRADED my computer to windows 10 home. LATELY i am having problems with my graphics card gefore gtx620 and my 1tb HARD drive. i changed my graphics card to a msi geforce gtx1050ti w/4gb mem and brought a Seagate 1TB BarraCuda 6Gb/s ST1000DM010 3.5" Drive with Dell Windows 10 Included. i also upgraded the ram of the computer to 12gb.The graphics card works fine and so does the ram. Here's where i'm stuck. My computers bios is on LEGACY mode and i want to clone my old drive which is a 1tb toshiba st1000 also but my old hd is in mbr format and the new hdd is stating GPT. i already connected both drives to the internal casing and am ready to clone. I am using Macrium reflect 7 to clone the drives but since one drive is in mbr format(C: local) and the new in Gpt format (newly installed)im afraid after cloning, my new drive will not BOOT up in bios when i replace the old hd for the new. Also i'm not seeing anything on disk management that states the new drive has windows 10 installed. all i see is two partitions on the new drive that says (1)none partition unformatted and (2)data ntsf primary. can someone please help me here.Sorry for the long explanation.
