I just installed from the DVD-ISO image over Ubuntu 12. System will not boot from HD. I can get grub2 menu and have tried the nomodeset option. However, even in recovery mode, the system hangs when trying to start in fail-safe X-mode. I just get a black screen with blinking cursor. Even worse, system doesn't respond to Alt-Ctrl-Delete and requires a system power down to get restarted!
Yes, I have an NVidia card (550-ti) which is mature and pretty generic. Any suggestions ?
I can boot from the Live-DVD, but can't adjust monitors or get X-config for NVidia running from the Live version. After disabling 'quiet' in the boot cmd, I can see it run through and auto-login after which it just blinks the cursor with no further msgs.
