Windows 10 Installer deletes linux partition

I have a Ubuntu and windows dual-boot and while upgrading to widows 10 during one of the restarts grub wouldn't boot a partition and went into recovery so I used a Ubuntu live CD and GParted informed
me that my linux partition was missing. It was listed as un-allocated. This means that the Windows 10 installer deleted that partition. (The helpdesk told me to post it here)

 

How to go about building a tri-boot system?

i dual boot all the time, and going in to tri boot is easy.

step 1) partition the drive in to 3 partitions ( leaving 1 empty for the linux installer. )
step 2) install windows on the first 2 partitions.
step 3) install linux, and let it auto partition the remaining space. ( i recommend at least 30gb of space for linux, because it will make things a lot easier. )

step 4) enjoy.
