Sudo command not found

Local.

Windows shows if I hold alt, but when booting it says there's no boot disk, insert disk to continue.

If I boot into osx I can still see all my files on Windows and the untitled fat 32 drive is still there which is the one I was hoping to merge with boot camp.

If it helps I also have a second drive with a second copy of osx on it which also works fine.

Sudo works fine within osx but not in recovery. Terminal also says bash in recovery instead of my computer name if that is an issue.

Still trying to fix the windows boot camp problem.

I decreased the OSX partition to create a third partition that I intend to merge with Windows.

I've managed to use Tuxera to format the extra partition as NTFS.

When I restart and try to boot into Windows I get this message:

BOOTMGR is missing

Press ctrl alt del to restart.

Thank you, none of the guides I read before starting this mentioned that my windows would become unbootable. I thought I'd just be able to log in to Windows and merge the two. Then when I couldn't, I find all this on the forums.

Can using a Windows 10 install disk fix the issue or do I have to use that GPT? It looks like it's very easy to mess it all up as I don't really understand any of it.

Thanks again for your help.

Unfortunately my screenshot only shows the first page because I didn't realise you could expand the window at this point, do I need to provide the entire list of files?
