I have Windows 7. I tried to install Ubuntu and the installation was almost over when an error message popped up and the installation failed. Then I rebooted the computer but the computer wont start. A blank screen appeared and nothing is happening. The same thing is happening every time I am starting my computer. How can I solve it? Please help.

Try to hold down the Shift key during PC boot and see if a boot menu appears

or

try to use the boot-repair program from a LiveCD-USB of Ubuntu to repair the bootloader.

At this point, the easiest thing is probably to install Ubuntu again. If it fails a second time, make a note of the exact error message so you can put it in a question. As it is now, there's not too much anyone can say to help you as you haven't given sufficient information.

To fix grub boot loder follow this guide.

You need Ubuntu 12.04 livecd for repairing grub boot loader . Here assuming the Ubuntu partition is sda7. Boot up ubuntu from the livecd,open terminal and run:

sudo -i and see what is your linux partition and note it I assume it sda7 here.

mount /dev/sda7 /mnt  

mount /dev/sda7 /mnt/boot

grub-install --root-directory=/mnt/ /dev/sda

mount --bind /proc /mnt/proc

mount --bind /dev /mnt/dev

mount --bind /sys /mnt/sys

chroot /mnt update-grub

umount /mnt/sys

umount /mnt/dev

umount /mnt/proc

exit
