How to install Tiny Core Linux 8.0 in ESXi 5.5

It's not totally clear what you're asking, but you can use the tce-install extension to both install in a vm and on real hardware.

Persistence can be as easy as running the command "filetool.sh -b"

I use ISO to load, then run tc-install and choose CDROM option, it runs well,

was select from running OS, but it didnt success, maybe i forget something,

Once you've booted the vm from the iso, it would be better to choose the install to hd (the vm hd) option

Try the download from web option. ([N]et)
It'll  install a clean core-only on your virtual disk (whole disk)

The "select from running OS" is for migrating a existing installation,
when you manually select the path to your local kernel.
