I have an external drive with Linux Mint 18 on it. It boots to my desktop, which is where I used the live CD to install the OS onto the external drive. However, when I try to boot this external drive from my laptop, it will not boot.
Now, I changed the boot menu, made sure I set "Secure Boot" to disabled, and verified that "UEFI boot" is set to enabled, and I still cannot get the drive to boot. I used EasyBCD to install a grub, but that also puts me into the grub menu upon boot. I am not able to see the drive in windows explorer, but it is in the Manage Disks. I tried all of the EasyBCD grub options to no avail.
Am I missing something? I do not want to take a chance and install the grub from the command when it first boots, (I get this message: Minimal BASH-like line editing is supported. For the first word. TAB lists possible command completions. Anywhere else TAB Lists possible device or file complete
) because I do not want to take that chance and wipe out my windows boot, or more. When I boot it to my desktop, I get the options from grub asking whether to boot to Linux or Windows.
What am I missing? Can I just add a grub through EasyBCD and if so, which procedure is it? I would like to get this grub on my laptop so that when it boots, I get the option to boot to either Linux or Windows when the drive is plugged in. I want to be able to install this drive to any computer and be able to boot into the Linux OS on this external drive. Even if I have to change the BOIS setting upon boot. That does not bother me.
I was also thinking of just reinstalling the live CD again, only this time, use my laptop to perform the install to "the same" external drive I have Linux Mint 18 on right now. Basically overwriting the OS to the same OS. This way, the grub is on my laptop as well.
However, when I do this, I was thinking about removing the two drives I have in the laptop before installing. My question about this is, "if I do remove the drives, will this work, because I didn't remove the drive from my desktop when I installed the initial OS on the external drive. Does this grub play a role within the C:/? Any help would be greatly appreciated.
