I have Ubuntu 16.04 installed and running fine. It boots from an SSD and has a larger HD for storage.

I would like to install Windows 10 for gaming and have bought an SSD specifically for Windows.

Normally you would go the other way around, Windows first and then Ubuntu, but I don't really want to reinstall Ubuntu.

Is disconnecting the two "Linux" hard drives and only connecting the new SSD for Windows, while installing Windows the way to go? Afterwards I would connect all three HDs and set the Ubuntu SSD as the boot drive.

I don't mind having to go into the BIOS when I need to boot in Windows, if necessary.

TLDR: Ubuntu installed on SSD, want Windows 10 installed on second SSD. Disconnect Ubuntu SSD, install Windows 10, reconnect Ubuntu SSD, boot from desired SSD. Feasible?

  • Are you asking specifically about SSD because search for "installing windows after ubuntu" finds lots of duplicates, including this one: askubuntu.com/questions/129058/…? In that case perhaps make your title more precise.

  • I'm asking specifically if installing Windows on its own SSD alongside an SSD with Ubuntu. The duplicates mostly concerns single-drive dual-boot instalations. EDIT: I've clarified the question in the title.

1 Answer 1


I went ahead and did it. The operation was successful.


  1. Disconnected the Linux HDs
  2. Connected the new SSD
  3. Installed Windows on the new SSD
  4. Reconnected the Linux HDs
  5. Set the Linux SSD as default boot-drive
  6. Booted into Ubuntu
  7. Mounted the Windows partition in Nautilus
  8. Ran sudo update-grub

Grub now presents me with a list on startup were I can choose between Ubuntu and Windows.

The only small problem I had was in step 7. For some reason Ubuntu claimed that Windows had not shut down properly and thus could't mount the disk. A quick reboot into Windows and then back into Ubuntu solved it, and the drive mounted fine.

I'm not sure if disconnecting the Linux HDs were actually necessary. I did it to be extra sure I wouldn't accidentally mess up the Ubuntu installation. The Windows and Ubuntu installs are on identical SSDs.

    You mean "between Ubuntu and Windows", not Ubuntu and Linux :) Jan 9, 2017 at 6:56

  • Worked for me as well. Had same issue on step 7 and instead of restarting I mounted the EFI partition using the Disk utility
