I'm a Linux newbie here. Never really did much in the past after dual booting other distros maybe 10-15 years ago. So, I plan to really start with Linux using ZorinOS 16 as Win11 won't officially work on any of my computers manufactured from 2008-2015.
I wanted to install ZorinOS 16 dual booting with Win10(21H1), but, the option to do so is not listed. My HDD is an original 150GB with ~6GB original Vista recovery, and the 2nd partion fully utilized for Win10. There's no other partitions or unallocated one.
I disabled FastBoot under Advanced Power Settings (Lids Actions) in Win10. My laptop is too old to have UEFI or SecureBoot, and only has TPM 1.2. I tried both Core and Pro iso from official Zorin's website as I gladly paid to help the Zorin cause.
My Dell XPS 13-9343 allowed me to dual boot install easily though.
What am I missing here on my Lenovo x61?
