Question Multiboot ubuntu/windows 7 encrypted with Trycrypt


I have a netbook with one drive and first installed Windows 7 (C) followed by Ubuntu (D) in different partitions. Now I want to install Truecrypt.


Q1: For this I need to know where GRUB is: in the bootsector of the partition of Windows or Ubuntu ? From googling I understand it should be in the Ubuntu partion. Just want to be sure, because this leads to my second question.

Q 2: If Q1=yes, then I understand that encrypting the windows partition will give the following behaviour: starting the computer will present the choice for Windows 7 or Ubuntu. If I choose Ubuntu, it will start right away. Only if I start Windows I will be asked for my password. Is this right ?

Q 3: If Q1=yes, then I understand that encrypting the Ubuntu partition in stead will give the following behaviour: after starting the computer I will directly be asked for my password, next the choice for window 7 or Ubuntu will appear. Choosing Windows will decrypt the windows partition. (Choosing Ubuntu will start Ubuntu without the need to decrypt.)

Q4: if Q3=yes, can I encrypt the Ubuntu partition with the same password as in Q3 ? Will this lead to the decryption of Ubuntu if in Q3 I choose Ubuntu, without to give in my password in a second time ?

Thanks.

Grub, as defaults, is installed on the mbr on the first hdd.
But you could install it even on the partition linux.
Or you could even don't install it at all.

I don't think there are problem using the same password between two different systems, however truecrypt have an extensive documentation so you should facilitated to understand its functioning.

Are you sure? From the documentation I understand that in the MBR there is a pointer to Grub which itself is in the bootsector of the ubuntu partition ?!

I am attempting to use Truecrypt on a multiboot also, Ubuntu and Windows 7. Did you manage to this successfully?

I am worried if I try this it will corrupt the MBR and ruin the booting process.

Any information you have on this would be helpful!
