So i try to install Linux Manjaro/Mint on my w10 rig (i have 2hdd and 1sdd for OS (currently win10 ripped to bones LTSC(i don't thing this information have any value BUT i don't know what information have value in my case))).
I follow this "guide" (and shrink 100gb of HDD) all go very good, i create boot-usb, load Manjaro from it(i'm writing this post from Manjaro), and here come problem i try to install it and "this" error massage popup (why it happens (as i believe)).
I try to install old and new versions of BIOS, try to play with UEFI/Legacy, fastboot, safeboot, (and myriad other SATA/drives/boot related settings).

Q/A

Q:My motherboard?
A:"GA-F2A68HM-DS2 (rev. 1.1)" (AMD) (it pretty old).

Q:Output of fdisk?
A:fdisk.

Q:Output of dmesg?
A:dmesg.

Q:Raid?
A:No.

Q:Bios?
A:I try update and downgrade it. "Here some photos of it" (i try to change MANY settings so photos outdated).

Q:Chipset?
A:"A68H".

Q: Distros?
A:"Manjaro KDE", "Manjaro xfce Minimal", "Mint Cinnamon".


Thank for any help! (I thing it my last chance to fix it, after gonna drop that and stick to Windows (at least before i decide to upgrade my rig))

When you shrank the partition to get the 100 GB space, what was done with it? Did you leave it unconfigured? or did you already partition it?

Are you sure you selected that drive to do the install on?

The error message seems that either you did not leave open unused space, or did not select the proper drive for the install.

The only drive that shows up with the fdisk output (sda) appears to be a 16 GB USB flash drive

Are you sure ?. Check the firmware (BIOS) for disk architecture - for Linux it needs to be AHCI not RAID. If you change it though, you will lose access to Win10 unless you tell it first IIRC.
