Hello,

 

I am trying to encrypt my computer using TrueCrypt; I am receiving the error: "Your system drive has a GUID partition table (GPT). Currently, only drives with a MBR partition table are supported."

 

I am watching youtube videos, so I may be trying to encrypt my computer wrong, or maybe I can't encrypt this computer? If anyone has any knowledge or help on how I can encrpyt my computer, ideally using TrueCrypt, it would be greatly appreciated.

 

Windows 7  - SP1

64-bit 

 

 

Kindest Regards,

ClearlyTrying

No, you are doing it right, but your drive is formatted with a GPT and TrueCrypt does not support that.

 

So you'll need to use an encryption program that does support it, like BitLocker, provided you have the right Windows 7 version.

I will try BitLocker, thanks!!  :cool:

Bitlocker is not on my version of Windows 7 :(

 

Windows 7 Home Premium is my OS, should have stated that originally. Do you know of any program that can encrypt Windows 7 sufficiently. After doing a little google searching(I will do more), I have only read about TrueCrypt and now Bitlocker. I can probably find a random program, but I would feel a lot more comfortable using a product/program that is recognized, malware-free, sufficient encryption(opposed to finding one on my own, through Google). If you or anyone knows of a program that supports Windows 7 Home, I would greatly appreciate it.(I will do some google searching to see what I can come up with.)

 

Regards,

ClearlyTrying

With Google I find a solution, but I'm not going to recommend it, I've never used it.

Full disk encryption has to be very reliable, lest you loose your data.

Thanks for the suggestions. I decided to upgrade from W7 Home , to W7 Ultimate. I am now using Bit Locker. I hope it is as safe as TrueCrype. I was messing around with TrueCrypt and noticed you got to determine how long/complex the algorithm was by moving your mouse rapidly across the screen for approx. 30 seconds, and other features that helped determine the strength of the encryption. On BitLocker I don't have the option to ask for password upon boot. I also didn't realize I needed a special chip to use BitLocker, so I can't store my 'key' in my computer, i had to store my key on a Cd-Rom,Dvd, or USB. So I guess that is my only option for a key. 

 

Anyways assuming that BitLocker has done a sufficient full disk encryption, what other measures can I take to remain safe, secure, and anonymous. I am very skeptical when it comes to online banking, but am finding myself with little options and would like to use the features, but only after making sure I have done every basic safety measure I can. Would using a Virtual Machine to browse the internet/banking/online shopping, when I post on youtube, or forums, i would like to remain anonymous if possible. I don't like the idea of ads and others knowing where I am posting from. 

 

Kindest Regards,

ClearlyTrying

I didn't expect you would upgrade to get BitLocker, otherwise I would have told you more about it, like the TPM chip.

 

You should also create a recovery password for your BitLocker drive.

It's alright. I was contemplating the upgrade for a little bit anyways.. 

 

Still wondering how to safely, securely, anonymously surf the web to use online banking, shopping, etc. If I understand correct, I can use a VM to browse the web?

You can use a virtual machine. Do you know if your online banking works fine on a browser like Firefox or Chrome? i.e. that it doesn't need ActiveX controls?

Because then you could run Linux as a VM.

I don't know. Is there a way for me to determine that?

 

I'm assuming that a Linux VM, is more secure then a Windows VM?

Just install Firefox on your Windows machine and try to do banking.

 

By using Linux, you significantly reduce the amount of malware that can attack your machine, because most malware is for Windows.
