1200 restore help?

[Retro_71]

if you have a workbench floppy and directory opus then you can at least boot to your hard drive but the problems is unless you have a backup (which by the way i recommend you do) it will be hard to see what got deleted. Check S, C, L first and then work your way thru to the other directories to see what is missing.
Not booting could be she wiped the S dir or one of the startup-sequences.

even from the cli try typing in dir dh0: or hd0: (or whatever your bootable hard drive is)
if dir doesn't work try c/dir or dh0:c/dir dh0: and see if s directory is there and then dir s/ (dh0:c/dir dh0:s/ ) and see if you can see startup-seqence, user-startup, ed-startup, Shell-startup if not then you are missing them and that's the reason why it is not booting
