I'm dual booting Windows 8.1 and Linux Mint. I decided to install the Linux Mint OS (Rebecca) onto an EXTERNAL HDD.
So what I did was click "Something Else" during installation and I created 3 partitions on the External HDD.
- EFI Partition
- Swap Partition
- Root "/" Partition
Note: There's no more free space after that. The above 3 partitions took all of it (as intended).
Then at the very bottom, I chose to install the bootloader to /dev/ssd instead of /dev/sda.
When I was finished installing mint and I booted into windows, I ran the following batch file as Administrator:
@echo off mountvol b: /s taskkill /F /IM explorer.exe start explorer.exe start explorer.exe
Then I went to my Windows (Internal HDD) EFI partition.. And there it is! GRUB is installed in the EFI folder as "Ubuntu":
And when I check my BIOS, there's 2 new options to boot "Ubuntu". I don't want this. I want to have everyone only on the external drive (EFI partition and all). It has to be possible. I did it with my hackintosh (Clover EFI) but can't seem to figure out how to do it with GRUB..
No matter what I do, it keeps messing with my internal MBR and installing to the internal EFI partition. Would be even better if I can just boot it without grub.
