Due to post size imitation, I cannot post full log of installation

I have seen this in the past and it seemed to be related to the drive having the partitions already in place. I solved it by changing the partitioning and re-running the installer and selecting the ‘destructive’ option to freshly partition correctly.

Hopefully someone will have a more complete answer as to why it fails but for now you might want to try that.

MS.Win10 & Arch Linux, already installed and I use Arch for development. So destructive may not be an good option.
But Thanks.

I just found more detail, that may help to figure out whats went wrong:
