Thread: Freeze at boot

hi,
installed ubuntu 11.10 64 on hp z210 workstation (i7 2600 cpu, nvidia quadro 2000).
had trouble starting installation process or item grub menu whatever selected, got frozen black screen. managed install adding nomodeset parameter grub item command line using manual mode (pressing 'e' on grub screen, modifying command line adding 'nomodeset', , pressing f10).
installation fine computer won't boot.
freezes on black screen blinking cursor.
guess there still problem graphic card.

tried advice post http://ubuntuforums.org/showthread.php?t=1743535:
grub menu did not appear @ startup pressed shift key multiple times nothing happenned.
booted live cd using nomodeset option.
when did ubuntu installation, installed on different partitions :
/boot (sda1)
/ (sda2)
swap (sda3)
/usr (sda4)
/var (sda5)
/tmp (sda6)
/home (sda7)

commented out /etc/default/grub/ grub_hidden_timeout=00 , added nomodeset option grub_cmdline_linux_default="quiet splash".
saved file.
created dirs in /mnt in order mount different partition installed ubuntu:
mkdir /mnt/boot
mkdir /mnt/usr
mkdir /mnt/var
mkdir /mnt/tmp
mkdir /mnt/home

mounted partitions corresponding directory:
mount /dev/sda1 /mnt/boot
mount /dev/sda2 /mnt/
mount /dev/sda4 /mnt/usr
mount /dev/sda5 /mnt/var
mount /dev/sda6 /mnt/tmp
mount /dev/sda7 /mnt/home

did binding:
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys

chroot /mnt:
sudo chroot /mnt
updated grub:
update-grub
seems fine:
generating grub.cfg...
done

reboot still block on blinking cursor.

reinstalled grub using same kind of process. got still same thing.

modified /etc/default/grub what's advised in http://ubuntuforums.org/showpost.php...&postcount=845.
changed grub_cmdline_linux_default grub_cmdline_linux_default="vga-791"
, added grub_gfxpayload_linux=text @ end of file , saved it.
updated grub.
rebooted.
still same black screen blinking cursor. tried again multiple press on shift key. nothing moved.
