Boot the windows installer as you did previously (either dvd or usb, whichever is easier for you).Ģ.

In your case, reinstalling and sorting this issue permanently would involve doing the following steps now:ġ. This happened because Windows detected the EFI partition on Disk 2 during install, and used that as it's default boot configuration data store. To prevent this in future, remove any non-data partitions from the drives you do NOT want windows on.

If your hard drive dies or is removed, your SSD will become unbootable without being regenerated, which is hard to do when the system is already configured like this. Windows will automatically use the same bootloader if another install is already present, meaning that you're stuck now with your hard drive containing your boot order. The reason this happened is that you installed Windows when there was already a disk installed in the machine set as a 'system' drive, with an EFI partition. Now that I've included that information on what you need to do to fix this, I'd like to answer one of your main questions from your post.
