help with grub

[sflu]

I recently re-installed ubuntu 8.04 in a dual boot set up with vista and now in the grub menu i have duplicate entries of ubuntu. Can i delete any of these safely so they do not show. below is what i have now and have it set up to boot from the vista loader first. I arrow up and choose the ubuntu OS when i want to use ubuntu. I have the default num set at 6 and i am assuming that i would need to change that should i delete any entries.

You mean like that?
Change the default to 0 for Ubuntu or 1 for Windows.

so i can delete the other entries and just change from 0-1?

You can do that. I would also be tempted to keep the recovery mode for that kernel also, but that is up to you.
The only reason to keep the older kernels on the boot order is that you can boot into them if the newest update made some hardware stop working.

Thanks Hal. Much appreciated.

Keep in mind, that if your system updates grub, it might restore these deleted entries and you'll have to delete them again.
