How to solve “cannot display this video mode optimum resolution 1280 * 1024 60 Hz” problem in ubuntu 11.04 and windows 7 (Dual booting)


After installing windows 7 and ubuntu 11.04 in a system some times you will not see GNU GRUB. You will get “cannot display this video mode optimum resolution 1280 * 1024 60 Hz” massage on monitor and it will open ubuntu 11.04 directly and you can not chose between ubuntu 11.04 or windows 7

To solve this problem first update system through Terminal type this command $ sudo apt-get update
After update is over you go to update manager and see any updates are available if updates are there just update them. After that you go to “ubuntu software centre” and type “startup-manager” in such place and enter. You will see startup-manager and just press install button it will install

Now open startup-manager

You will see by default operating system is ubuntu 11.04

You have to put Display resolution as 640 * 480
Colour depth as 8 bits
(You have to select both show boot splash and show text during boot)
Misc [*] show boot splash
[*] show text during boot

And go to advanced put boot loader menu resolution is 640 * 480 and close now and restart the system

This time you will see this

GNU GRUB VERSION 1.99 rc1-12 UBUNTU 1

Ubuntu, with Linux 2.6.38-8-generic

Ubuntu, with Linux 2.6.38-8-generic (Recovery mode)

Previous Linux versions

Memory test (Memest 86+ )

Memory test (Memtest 86+, serial console 115200)

Windows 7 (loader) (on/dev/sda 1)

Now you can select ubuntu or windows

Enjoy now
