Windows 10 upgrade and Truecrypt
Can you safely upgrade from Windows 7 to Windows 10 when using Truecrypt 7.1a without risk of corrupting the bootloader and without first decrypting the drive?

TrueCrypt is no longer supported.
You should decrypt your hard disk and any other data before upgrading as otherwise you cannot be sure you will be able to retrieve your data.
If you wish to still use unsupported software
Some people have stated that TrueCrypt still works with Windows 10.
- Decrypt the disk, do the upgrade, then make sure TrueCrypt still functions after the upgrade.
- Make backups should be made before and after you encrypt the HDD and perform that first reboot.
The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP. Windows 8/7/Vista and later offer integrated support for encrypted disks and virtual disk images. Such integrated support is also available on other platforms (click here for more information). You should migrate any data encrypted by TrueCrypt to encrypted disks or virtual disk images supported on your platform.

It is likely to be incompatible. It is always recommended you decrypt your hard disk and any other data before upgrading an operating system or else it will not be accessible after upgrading.

Do NOT upgrade on a System-encrypted-TrueCrypt drive!
you have to decrypt -> upgrade -> encrypt
