A problem using Bing

My intent is to format a P166 for use as a DOS computer.
It had W95, a prior uninstall of Norton AV caused error screens so I had to
format.

When I tried a W95 boot disk, format, got error: insufficient memory to
load system files.

I then ran Bing, it did format, I rebooted with the W95 boot disk, at A:,
entered C:, no C:.

Ran Bing again, named the drive C, but see legend that the drive is not
available to anything as it has Bing installed on it.

Then rebooted with W95 boot disk, message: can't find Bing, assume it wants
the Bing boot disk.

I need to wind up with a C drive for DOS, and have created something else.

Advice?
