I am currently running Windows 7. My User folder is mapped to a different drive then the drive that my OS in installed on. I mapped the users folder to the other drive while installing windows.

I want to encrypt the whole drive with the "Users" folder. Is there any way I can use TrueCrypt to encrypt the whole drive, but make it so Windows can still have access to it upon booting?

How is the Users folder linked? Is it a hard link or symlink? I believe you can use BitLocker to encrypt A: if you use a hard link it might ask for a password when you startup. Just a theory. –  wolfo9999 Aug 17 '13 at 19:12
    
It is not linked. Windows is actually looking at that location for the users folder. I followed these instructions when installing answers.microsoft.com/en-us/windows/forum/windows_7-files/… –  Keegan McCarthy Aug 17 '13 at 19:18
    
Why would you want to encrypt a whole drive? Afterwards access times could be terrible, since you need to decrypt every time you need to access data, AFAIK. –  Doktoro Reichard Aug 17 '13 at 19:19
    
The method in the article is making a "junction" which is essentially a hard link. Mounting a drive to an empty folder. I'm guessing you want to encrypt the partition not the entire drive. Should be possible using BitLocker. –  wolfo9999 Aug 17 '13 at 19:25
    
@DoktoroReichard Actually the drivers truecrypt uses for whole drive encryption are fairly fast, from what I have seen worst case 10% performance loss, but normally only 1 or 2% –  Scott Chamberlain Aug 18 '13 at 3:51

You can use TrueCrypt to encrypt a partition with pre-boot authentication. Start with this tutorial and use hidden TrueCrypt volume in step 4.

More information about encryption softwares can be found from this Wikipedia page along with a good comparison charts.

Perhaps I am missing something, but it seems pre-boot authentication requires you to encrypt the system volume as well. Can it be done without it? –  Suma Jan 13 at 14:48
