"Legacy BIOS", dynamic/basic, GPT/MBR disk??

Hello!

I want to set a full disk encryption with TrueCrypt on a Win7 Ultimate x64 system.

Lurking around TC forums (I can't post there) I gathered some information that might be very important.

First of all, they say, in order to have a FDE, the motherboard must have a "legacy BIOS" and not a different kind of BIOS. I don't know what it means. My motherboard is ASUS Sabertooth X58. What kind of BIOS does it have?

Second, my OS and System reserved partition are on Disk 4. At TC forums they say that TC looks for the bootloader on the Disk 0 and if it doesn't find it there the system won't boot. Is there a way I could make Disk 4 (OS drive) be Disk 0 and Disk 0 be Disk 4?

Third, my system drive is a dynamic disk. I am not sure yet if that affects the FDE in any way, but how can I change it to basic disk? I am talking about the drive with 100MB System Reserved partition and C partition with OS on it.

Fourth, how can I know if my system disk is GPT or MBR disk and if it's GPT how can I change it to MBR disk?


I don't have much time to set up the FDE so I would kindly ask any knowledgeable person to help me out on this.

Thanks in advance

 

I've found so far that PGP and TrueCrypt don't support FDE of dynamic disks while DiskCryptor does.

Apparently, Partition Wizard Boot CD can convert the system disk from dynamic to basic. I'll try to do that.

I found out that Windows Disk Management lists my system disk as MBR disk.

So, there are two things left to solve: BIOS type and swapping disks 4 and 0.

Anyone?
