install ubuntu along side Win?

[frank55]

Hi guys;i've been trying to install Ubuntu along side Win 10TP in my Lenovo ThinkCenter71; Intel (core)tm) I5 2400 CPU 3.10GHZ,
Mem 3.8GB,Socket 1155, Video card ATI 6450, HDD Sata 500.

i try to follow instructions bellow link,

i wonder why in the auto partitions it doesn't show ''install along side '' as it should like in this Picture, see pic.

have you legacy support ON in the bios?
UEFI bios'es need to have enabled legacy support in order to boot from certain partitions with certain software. I hate UEFI.

My laptop was really fiddly to get ubuntu booting, at it was to do with UEFI and legacy mode.

I installed windows first and then installed Linux Mint, then 6 months later I realised i hadn't booted into windows once.
