patseguin Global Moderator Posted February 21, 2016 Global Moderator Share Posted February 21, 2016 I am downloading Linux Mint Cinnamon and will be making a USB boot drive and then want to install it on an external SSD to tinker with. How well will it run? Just as fast as running on an internal drive? Link to comment Share on other sites More sharing options...
patseguin Global Moderator Posted February 21, 2016 Author Global Moderator Share Posted February 21, 2016 Well, naturally it's not working. It says something about invalid extent and I have a command prompt with grub rescue mode. Any idea what that's all about? Link to comment Share on other sites More sharing options...
kozukumi Posted February 21, 2016 Share Posted February 21, 2016 Depends if your BIOS/UEFI supports booting off the external USB SSD. Also some external enclosures do not support booting so the controller firmware won't report itself as bootable to the BIOS and the BIOS will just skip it.

I've had it before that it tried to install to the hard drive in my PC, hence why no booting for me. Link to comment Share on other sites More sharing options...
patseguin Global Moderator Posted February 21, 2016 Author Global Moderator Share Posted February 21, 2016 Well, I got it to work but not great. I installed Freya and I get constant errors. Not worth the time really since I was just tinkering anyways. I also installed it on my 4TB external HDD but it wouldn't boot off that at all.
