VeraCrypt (TrueCrypt) won’t let me encrypt my system drive

SOS users are often reminded of the importance of disk encryption to keep their precious data safe in the event of computer loss or theft. For many years we have been recommending use of TrueCrypt, which now has been re-born as VeraCrypt, or Microsoft’s BitLocker feature (Available in Pro and Enterprise versions of Windows).

Here’s an article that explains how to upgrade from Windows 10 Home to Windows 10 Pro.

For those using non-commercial versions of Windows such as Windows Home, VeraCrypt is a free, proven, reliable, and effective option, and full disk encryption is recommended. There can be a hitch, however. At present You can only encrypt the boot (main) drive in your computer if it is partitioned with the older MBR method. There are several YouTube videos and articles on the web that show various techniques that can be used to convert a drive from GPT to MBR, after which you can use all the features of VeraCrypt. It is possible to lose ALL your data converting from GPT to MBR, so it is ESSENTIAL that you back up your entire C drive before proceeding with any of those tools. If your drive is partitioned as GPT, GUID, UEFI, or EFI, and you are not technically oriented, you might be better off just upgrading Windows to the Pro version and using Microsoft’s BitLocker feature.
