    Putting Windows 10 on C: drive and data on another?


    I've only ever used one drive all my life. I am now going to be building my own computer with more than one drive (plus backup external drive).

    This may seem like a dumb question, but I was thinking of putting Windows 10 (and drivers) only on my C: drive, and then putting all my data on other drives. My question is, if my C: drive gets corrupted, does it affect any of the other drives? Or vice versa? And if I need to reinstall Windows on my C: drive, would all the data on my other drives still be intact?

    Thanks.

    :)

  3. No C: but D: drive has all the data

    Hi Austin,

    To help you with your concern regarding the data on the drive C:, you're seeing the drive "C:" as the drive "D:" because you're booting your computer outside Windows. When booting your computer outside Windows, the system is reading the recovery partition
    as drive C: and the data in the drive C: \ are listed on the drive D: \. Try to boot your computer and try to check again the data in the drive C: \ and see if the data are listed.

    Regards.

    GPT disk conversion for both data drives and C drive


    Macrium Rescue disk can be used to convert from MBR to GPT and vice versa without doing a fresh install of Windows.

    1. Download Rescue6.1.1081X64.iso - Google Drive and use Rufus to create a bootable USB disk. Skip this step if you've already created the Macrium Rescue disk.
    2. Download: BootEFI_Only-00-00.zip - Google Drive . Unzip to an external or an internal HD
      NOTE:
      This is a copy of the first 3 partitions of my current Windows 10 x64 (450MB Recovery, 100MB EFI and 16MB MSR)
    3. Boot up Macrium Rescue disk and create a backup of your current Windows to another internal/external HD. It serves 2 purposes: you'd have a backup of your current Windows in case things go wrong and then use it to restore the C drive on the next steps.
    4. Next, switch the BIOS to UEFI and use Macrium to restore the first 3 partitions downloaded in step 2 to your current MBR Windows. No need to convert or Format, Macrium will do it.
    5. Again with Macrium, select the backup image from step 3, and copy back the C drive after the 3 partitions.
      After this step, you should have: 450MB, 100MB, 16MB and C drive (GPT partition scheme)
    6. From Macrium, click on Fix the Windows Boot Problems
    7. Reboot. Your Windows should be in UEFI mode.
