I recently installed Ubuntu 12.04 onto my HP Pavilion, in an attempt to make the desktop able to dual-boot Windows 7 and Ubuntu. I managed to get down to the last step, and finished the installation process. After it prompted me to remove what I used to install Ubuntu, I did so, removing my SanDisk 8GB flash drive, and allowed the system to reboot.

Like usual, the desktop booted with the HP image, with the options at the bottom(Boot Menu, System Recovery, etc). However, when it should have started up with Ubuntu(like I'm certain it should have done), I received the following error:

Input signal out of range Change settings to 1600 x 900

From the time I installed the operating system, back in late August, till now, I've been trying to figure out how I would go about fixing this issue. My mom is also starting to get frustrated with my not having resolved the issue, as its the only desktop that has a printer installed.

Is there any possible way to resolve this?

To summarize the problem: -Successful boot -Screen brings up error -Screen goes to standby -Nothing else possible until desktop is rebooted, which will initiate the above three steps

A few notes: -I did not back up my computer before I installed Ubuntu. I didn't have anything to write to, and basically just forgot to. >: -I don't have a Recovery Disk. -I don't have the Windows 7 disk that is supposed to come with the computer. -It has been narrowed down by a friend on Skype that the problem lies with the display, and that the vga= boot command does have something to do with fixing the problem

Thank you in advance for resolving this problem. I greatly appreciate it. ^^
