Can I reinstall 3.9 without SD/FF?

During installation you will be asked whether you want to copy the CD-ROM driver and settings from the emergency disk. If you select "yes", it will also copy the gfx card driver.

Anyway you should make a backup of your current system partition so that you can restore missing files later.

You can reinstall the system with the monitor on CVPPC.

No, you can't. As soon as you install the gfx card driver, you are lost because the gfx card only shows the boot logo and you need a native monitor to switch the wb screen to the gfx card.

Better go the way of the emergency disk with installed gfx card driver. This works with every gfx card, even without emulation of native modes.
