Look like there is something wrong, after installed ubuntu

Hi, I just finished ubuntu installation (dual boot with vista). However, when I chose to start ubuntu on Grub menu, i got message (error to allocate memory resources if i remember correctly) before entering to boot skin, but i can enter to ubuntu properly. Any idea what is wrong and how can i fix it?

Another thing is when i updated ubuntu, in Grub menu i got more choices to choose. At first i got 1.Ubuntu, kernel 2.6.20-15-generic 2. Ubuntu, kernel 2.6.20-15-generic (recovery mode) and 3. windows vista, but now i have 2 more 1.Ubuntu, kernel 2.6.20-16-generic and 2.Ubuntu, kernel 2.6.20-16-generic (recovery mode). Is this normal? Can i delete old version of kernel since i got the new one? If so, can i just delete it in grub menu?

Thanks guys

 

I can't explain the error you encountered, but googling it is your best bet. With regards to the multiple kernel options in GRUB, you can delete the old kernel option; I do.

 

thanks dude ^_^

 

What is best is if you uninstall the old kernel, rather than just deleting the option. Uninstalling removes the files and the settings, rather than just the setting. Basically it'll look like this:

Code:

sudo apt-get remove linux-image-2.6.20-15-generic

Make sure your machine boots to the new kernel before removing any of the old ones, but if so, it's good to go

 

Many thanks Pita. As being newbies, i never know that kernel can be uninstalled. There are so many things i gotta learn in ubuntu ^_^.

 

As long as you don't uninstall your main, working kernel, Ubuntu should let you do just about anything
