Every time i install ubuntu to another partition on my computer my grub settings are changed. Eg getting the frequency out of range error and having to uncomment GRUB_GFXMODE=640x480 every install.

Does the importing accounts option on installation also import the current GRUB settings from the last OS ?

How can i stop the grub configuration being changed when doing a clean install on another hard drive partition.

I think you can simply change it in the file /etc/default/grub; change GRUB_GFXMODE=HHHxVVV to 640x480.

If you want to know more about grub, you can read the manual at this URL

Hi Marty,i know how to fix the issues in /etc/default/grub .I wanted to know how to stop the ubuntu installation,on a secondary partition, overriding changes already made to the /etc/default/grub with previous OS. – damien Sep 17 '12 at 0:32
You can do most things using the various configuration files, but it's possible to manually maintain grub.cfg, I think. One thing you can do is set GRUB_DISABLE_OS_PROBER=true in /etc/default/grub to keep it from changing existing entries. There may be a way to prevent the entire process of generating the grub.cfg, but I never tried. Or, you could go back to the original grub, I suppose. – Marty Fried Sep 17 '12 at 1:10
