DISKPART tried to create a Partition, has not worked

We're getting outside my comfort/experience zone here, but as I understand it - yes, the BCD should be in that Fat32 System partition.

These threads may help explain BCD a bit more...

No Windows Boot Manager on dual boot system (7 & 10)

If you want to see if Windows will boot, you can create a bootable USB stick with a temporary BCD on it which points to your Windows folder on the hard disk....

Use DISM to Repair Windows 10 Image (post #340)

This may also be informative (but bear in mind this would be on an MBR system)....

However, before doing anything to this drive that has the potential to wreck it further (if that's possible ) I would try to make a backup image of it on a external HDD so you have a fall-back possition. For that you need (preferably) Macrium Reflect - and for that you need to be able to boot Kyhi's rescue disk. Getting that to boot would be my top priority.

Hi ZBook

Good news, created Kyhi's Rescue Disk; initially had problem with new Sandisk USB. I've set up an internet connection from the laptop that needs fixing. I did a stupid thing, went into Macrium Reflect; only used the fix boot tab; without backing up the original disk settings - after rebooting it just went into 'please wait' mode. Only thing I've noticed is the following, originally:

Disk### Status Size Free

Disk 1 - Online - 54GB - 24GB

now:

Disk### Status Size Free

Disk 1 - Online - 14GB - 0GB

Not sure what that means. (Is it the USB Stick? Windows 10 ISO / WPE)
