Hello All,
I ran into a bit of a problem. I had a machine with 64GB disk space available, on which Windows 10 Pro was running. 64GB However proved to be slightly too short of what I required it to be. While the machine was running, I increased the disk size in ESXI (Edit -> Hard Disk 1 -> from 64 to 480). In windows I created a new volume of around 400GB with the new space that was available, and everything was just nice and as expected. Until I rebooted.
"An operating system wasn't found. Try disconnecting any drives that don't contain an operating system."
Now, I haven't changed anything other than increasing the disk size and adding a new volume. Why can't it find the operating system anymore? I went into the bios and checked if it somehow tried to boot off the other volume, but I can't even find it there; just "Hard Drive" with VMware Virtual SCSI Hard Drive and Bootable Add-in Cards "in" it. I have no idea how to resolve this issue, but I really can't miss this VM.
Any help or advice would be highly appreciated:)
Kind regards,
Remy

I have booted from the installation CD and removed the extra volume I've created. No success.
Tried to do a Start-up Repair, Uninstall Updates, System Restore, nothing works. They all just fail.
Diskpart at least still sees the 64gb volume as the C drive, so that's something.

I tried to rebuild the BCD, resulting in something rather unexpected. It successfully found a Windows installation, but when I tell it to add the installation to the boot list, it prompts me with "The requested system device cannot be found.", even though it just found it. urgh.

The hard disk is listed as SCSI, listing it as SATA or IDE doesn't work either.
