Hi all, I hope this is in the right category.
I recently picked up a 1TB external SSD on which I want to install both Windows 10 and Ubuntu 20.04, and be able to boot into either of those operating systems or the OS on the internal storage of the host computer.
I have already installed Ubuntu according to this guide here: How to Create a Truly Portable Ubuntu Installation on an External USB HDD or SSD
Unfortunately, I'm having trouble installing Windows 10 on the same drive. I set up Ubuntu to occupy 400GB on this drive, so I made another 400GB partition on which to install Windows 10, plus another 100GB reserved for storage. Neither Rufus or YUMI seem to be able to do the trick. Rufus threatens to format the entire drive instead of just the 400GB Windows partition, and YUMI is able to create a Windows to Go installation on there but I am unable to boot to it.
I assume the issue lies in setting up the boot manager on the external drive, as GRUB only detects the Windows installation on the hosts internal storage and Ubuntu, but not Windows to Go on the external drive. Any advice on how to proceed from here? I am considering trying WinToUSB as well
Thanks!
