However I've read stuff about the Ubuntu Boot Manager being installed on the first harddrive anyway and Windows not being able to boot any longer without the external harddrive connected.
Is there a need to disconnect the Windows Harddrive before installing Ubuntu on the external harddrive? No, Is like the same process when you create a live usb, you need to install the grub to the harddrive so the machine can boot from there.
Did you try to create like a live usb with your drive? Not yet, cause I was afraid to damage my installation. Do you know any good tutorial for that? I only installed Ubuntu on a main harddrive. You can take a look howtogeek.
If you don't pretend to use the entire disk I would suggest to have a usb with at least 64 G to store all you need. Remember that Ubuntu doesn't ask for too much drive space for the operating system so could use an 8G and test the performance.

CommunicativeAlgebra You can avoid this problem by disconnecting your internal drive before and during the installation process so that the installation of the bootloader can only go on the external drive.
Could you please explain it a bit. Nikhil It really depends on what kind of computer you have. In all cases, you should be properly grounded when touching any internal computer part.
For a tower computer, you just have to unplug the SATA cable from the drive before you do the installation. You can plug the SATA cable back into the drive sometime after installation. For a laptop, you have to unplug the drive from the computer.
Then, plug it back in sometime after installation. Nikhil If a laptop, disconnecting the drive may be more trouble than it is to use bootrepair to recover and it may be easier to use the bootrepair method instead of taking your laptop apart. However: You will have partition the external hard disk. Grub2 type installers that do work for persistent partitions on thumb drives do not seem to be working for USB hard drives, even with casper-rw files or partitions.
But the original poster wanted to keep all current files in the target drive, and mkusb will overwrite the partition table and create a new one. So it would not be an option for this case unless those data are backed up to another drive and restored after the persistent live system is installed. Add a comment. Full Install to USB Full installs are more stable and secure than persistent installs, but not as quick to make.
