Premise: I am aware it's perfectly possible to install Windows 10 and Ubuntu/Debian afterwards on the same drive (without ending up in a corrupted bootloader), but my current set up is different.
My current setup:
- Laptop with traditional HDD with Debian 8 installed on a fully-encrypted (LVM) internal disk
- The laptop has a Usb 3.0 port (and 2 Usb 2.0 ports)
- I have a usb 2.0 drive with Windows 10 bootable installer
- I have a usb 3.0 (type C compatible) SSD where I want to install WIndoed 10
The desired final setup:
- Windows 10 installed in the external SSD
- Windows 10 shall dual boot with Debian: either offering me to dual boot Debian or Windows 10 whenever the external SSD was connected on system boot, or alternatively boot directly Windows 10 whenever the external SSD was connection on system boot.
How do I obtain the final result, making sure not ending up with the Debian installation broken (or broken bootloader)?
