Question [FDE+UEFI] My Encrypted Mint-USB Installation Suddenly Doesn't Boot Anymore.


Hey,

firstly I'm a complete noob when it comes to Linux but managed to setup a fully encrypted usb stick with the help of this tool: https://github.com/CallumCameron/mint-encrypted-install

Which is based on this tutorial: https://community.linuxmint.com/tutorial/view/2061

It worked as it should, I started the PC, the boot-loader started, I had to enter the decryption password and it booted. This worked several times, but then I made a mistake and didn't reboot properly but instead just reset my computer and all of the sudden the stick won't boot anymore to Linux. It just skips the bootloader and boots into Windows. I don't really know why, the EFI partition seems normal to me. Could anyone help me? Took me the whole day to set this up and it would be sad if it would've been a waste of time.

Thanks in advance.

/e

I already tried the following tip from another forum, but that didn't help either, it just boots into Windows:

Quote:
Go into the firmware interface/BIOS and make sure that the USB is first in the boot order, that's a potential issue.
Also tried it on a different computer, Mint didn't boot either, but that can be because this computer doesn't support UEFI boot, just legacy.

This is how my EFI looks like in Windows, if that matters: http://i.imgur.com/Gm8fhtu.png

If you plug the usb stick into an already running system, do you get a prompt to enter a password to decrypt it?

Yes, that's what happens if I plug it in and the Mint Live-USB system is running.

Are you using grub on the usb? Reinstalling grub should fix it.
Code:
grub-install /dev/sdb
where /dev/sdb is the usb.
