Upgrade from build 10061 to 10074 fails (Inaccessible Boot Device)
Hi all,
I keep getting the Inaccessible Boot Device error when trying to upgrade from 10061 to 10074. I *think* this may be due to my symlinking the \Windows\System32\DriverStore\FileRepository folder to another partition on the same hard disk.
Why did I do such a thing? Well, that folder is 16 GB sitting pretty all by itself, plus Win 10, plus the update file(s), plus the new install, plus the temp files as stuff is transferred, and my 48.7 GB partition that I created is too full to update without that folder residing somewhere else.
I just wish MS had bothered to say "hey, you will need about 60 GB on the Win 10 partition if you want to actually use it as your daily driver"... I started with a ~20GB partition, resized it several times, and I'll be dipped if I have to go move to the 'left' and reconfigure all of my partitions yet again...
I already have:
1) symlinked my documents, pictures, videos, music etc to my data partition
2) told Steam to use the Steam library on my data partition
3) erased older Win 10 builds + drive cleanup of previous restore points, log files, etc, etc.
4) compressed the Win 10 partition (using the OS, not 3rd party)
I can't move the FileRepository folder back into the Win 10 partition or I won't be able to update due to a lack of ~10GB of drive space to play around in.
What do I do?
EDIT: Currently, I have 17.0 GB free on the Win 10 partition. I believe there's a Win 10 10074 update sitting in there... $Windows.~BT is there but only 200 MB, RecoveryImage is ~3 GB.
EDIT2: If I disable hibernation I can get ~4.75 GB back from the hiberfil.sys file. I still don't think that will allow a successful update if I move the FileRepository back though... maybe it could, now that I have compression enabled on the drive.
Does anyone have a way of getting an estimate for how much disk space Win 10 needs to upgrade?
