Dual Boot Screen

[kc9fsh]

I just installed Ubuntu, on my spare computer, it is installed my second hard drive and have it set-up as a dual boot system alongside Windows XP. Ran into a few issues but was able to resolve them by searching around online but the one issue I can't find a solution for is during the screen that would allow me to select Ubuntu or Windows XP my monitor comes up saying that it is a unsupported mode and won't show me anything for about 30 seconds until it boots to Ubuntu (by default I assume.) Is there a way to change some of the display settings at the dual boot screen?

Please post the output of:

cat /etc/default/grub

by enclosing in CODE tags (as I have) which can be used by highlighting all text and clicking hash (#) button at top of posting box.

What graphics do you have on your "spare computer"?
What is the 'Native Resolution' of your monitor?

Meanwhile you can:

$ gksu gedit /etc/default/grub

and EDIT the line which says #GRUB_GFXMODE=640x480 to GRUB_GFXMODE=1920x1080 ie, remove "#" in front of the line, if there is any, and change 640x480 to the native resolution of your monitor. Then,

$ sudo update-grub

See if it solves the issue. If not post the output of "cat /etc/default/grub".
