rittercon, you're doing an admirable job!
I think the easiest thing for you to try at this point (thanks for all of the great feedback) is to
par 1: shrink by 160 MB
par 2: move (0 MB before / 160 BM after) and resize to 260 MB (100 original + 160 claimed from par 1)
I'm tempted to suggest a 450 MB resize (350 MB from par 1), but I'm curious to see if the advanced 4k scheme is the issue or if it's a Win10 EFI system partition size issue.
I'll leave that decision up to you, it's your time and your machine. If you decide to make one stab at it,
par 1: shrink by 350 MB
par 2: move (0 MB before / 350 MB after) and resize to 450 MB (100 original + 350 claimed from par 1)
I suggest doing this with a bootable Minitool Partition Wizard
Select the 64 bit download and burn the ISO to a disc or use Rufus to put the ISO on a Flash drive
note that Rufus flagged the vesamenu.c32 as old and offered to update it - I did that when I built a PW 9.1 flash and it solved an old monitor issue that always split screen
I'd also like to know how your firmware is set up.
Is the setting:
Compatibility Support Module (CSM)
I looked at the MSI page (please confirm I went to the correct page for your board)
Type: AMI BIOS
Release Date: 2015-06-05
File Size: 6.08 MB
Description - Updated BIOS code to support 5th-Generation Intel Core Processors
***Support 5th-Generation Intel CPU requires VGA driver version 10.18.14.4206 or later
What version is on your machine?
It seems as though you're capable enough., but I'll be glad to answer any questions.
