But let's tell all. I have to remove this drive for later use. I install a blank drive then install Windows then add this data drive and copy in the files.
Installing an OS to a drive with files that have no backup is a very bad idea. We backup what we can't lose.
I had Windows 10 pro 64bit installed in my laptop, because of some issue I tried reinstalling it. While installing Windows 10 I formated the "c" drive, where Windows 10 was installed. Now I'm stuck this below error
"Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to the GPT disk"

I still have some data on some drives so I can not delete all the partitions. Can anybody tell me how can I overcome this issue. I want to reinstall Windows without losing the data.
