Quad Boot - Windows 10, 3 Linux O/S's

[HD7970GHZ]

Hi everyone.

I currently have a quad boot solid state drive in a laptop. It has Windows 10 and 3 Linux Distros.

Everything boots fine.

I want to encrypt my entire solid state drive (enveloping all 4 Operating systems and partitions) so that a password prompt will appear before the boot selection screen.

Anyone know how to do this?

I have heard that enabling full disk encryption in windows 10, it will not allow the Linux OS's to boot.

Add a password through BIOS so the computer can't be accessed at all without it. I recommend encrypting the partitions separately within each environment to avoid conflicts.

Hi Founders,

I was told to avoid BIOS passwords just in case I forget it someday. Apparently there is literally no way of resetting it, but I doubt that. Maybe I'll give that a shot. Thanks for the suggestion. :)

I am not familiar with encryption too much, but I did select encrypted install for an install of Linux Mint, but because I had another operating system on a different partition on the drive already, I could not select LVM or whatever encryption is used for install of the O/S. In otherwords, I have been informed that installing more than one operating system on a hard drive will make it impossible to fully encrypt additional O/S's. At least on the Installation.

Can we encrypt an operating system after it has been installed?

Yes you can, but i dont know if you can set a password to have before you select boot device/boot order, my advice would be to just encrypt all OSes separately

Thanks for responding.

So I would have to set a bios password that would encase all the individual encrypted OS partitions? That would be the first protective layer? Would that be enough?
