So I'm pretty much out of options after Googling and trying over & over again for a week so I'm hoping someone might have advice:
I'm not trying to upgrade from Win7/8 to 10 but from Win 10 (Version 1551 (OS Build 10586.1176)) to Windows 10 Fall Creators update. I get errors saying something like "couldn't write to reserved partition" (or something about the reserved partition), and an error code which I forgot but the new error code is: 0xc1900200
I've also tried disabling all Anti-Virus etc to no avail. I *think* it's based on the fact my reserved partition isn't large enough. The problem is, I can't resize it bigger because when I create a new chunk of unallocated disk space, it's not adjacent to that partition. I'm still confused as to if it's my 100 MB partition named "GPT (EFI System Partition)" or the 16 MB named "Reserved Partition" which I see using EaseUS Partition Master. Oh, and by the way, I've tried that one and AOMEI Partition Assistant Technician Edition 6.5, and MiniTool Partition Wizard. But whichever one it is, the 16 MB one or 100 MB one, they happen BEFORE my C:\ which is THEN followed by any extra space I try to create, as in the screenshot below which shows a 200 MB unallocated :
So, I figured maybe the only one is to MOVE that unallocated space NEXT to the reserved partition, but I can't find how. Anybody know how or has insight into what direction to take?
Also, just to clear things out for me, is the partition Win 10 needs is the 16 MB one or the 100 MB one? I know the 16 MB explicitely says "Reserved Partition" but I'm quite surprised that that partition would only be 16 MB.
