Hi there.
Unraid 6.8.3
Windows 10 VM running well with 60GB of space.
I wanted to increase VM disk space, so I shut down the VM, selected it, increased size from 60GB to 100GB, restarted.
Windows> Disk Management> selected c:> expand volume - this option was greyed out.
It showed
1. 100MB partition. 2. C 3. Healthy Recovery 4: unallocated.
I searched around and tried a few options (restart, create new volume from 4, etc. and had no luck.
At point one (the last point?) I right clicked on "C" and selected "Active Partition". The warning came up "if there's no OS you may not be able to boot".
I continued, with the intention of switching "active" back to the "100MB" partition. In the intervening few seconds, I tried to "expand volume" on C to see if it would work.
I then restarted BEFORE I set the 100MB back to "active". 100% my mistake.
So now on VM boot I receive a "BOOTMGR is missing" warning, press ALT CTRL DELETE which is just a boot loop.
Searching online suggests using a bootable Windows recovery DVD or USB, booting from that, and then selecting the 100MB as the active partition.
With my installation being a VM, I'm not sure how to do this.
I've searched the forums and reddit and so far the solutions for similar error have not worked (changing virtio, pressing a key to access a different Boot selection.
Any/all advice would be helpful.
And, if I must recreate the VM, that's fine, too. I won't lose any data, would just rather fix than start over.
Thanks so much.
