peter b :

I appreciate your help. I'm a beginner in Ubuntu.

would you simplify this for my beginner's understanding please ?

peter b (b1pete) said : #3

what you see above (cmds) and their output are the v minimum needed to identify ubuntu release you're using.

grub, ubuntu bootloader, went through major upgrades in the past, say, 4 releases or so. there are many things that must be considered before proper support can be offered.

from your post .....'Ubuntu, with Linux 2.635-28 Generic'..... it appears that you're TRYING TO USE/BOOT into ubuntu maverick release - that is the before last release called natty narwhal.

the very top grub menu entry is always the last installed ubuntu release and it'll boot up pending the way grub is set up to function - either with or without any input from user. personally I have grub set up to give me 10 sec to make up my mind what kernel I want to boot into. if no input from user exists within 10 secs grub will boot by default the v first grub menu entry.

there are many other grub settings that can be customized. there are many url's that offer insights/help on the inner workings of grub. ex


from what I could see on your post, it appears that you're experiencing problems with the file system; that's a v basic misconfiguration that requires a new install.

It use to count down 10 seconds also giving me a choice, but now it just opens on the choice section. And no matter what choice I choose (except the next to last one) it shows the error message i first included. i tried re-installing before; i got no reaction. also i think my CD drive was sabotaged. It wouldn't open no matter how many times I pressed the button to open it. I have a real mess on my hands.

well, you'll have to sort out your hardware problems FIRST - mandatory action that includes, besides your CD device, your HD BEFORE any attempt is made to reinstall.

if the pc hardware is in 'shaky' state for any reason or pure and simple unresponsive any ubuntu install attempt is doomed to failure.

so, fix your pc hardware first then reinstall ubuntu. if you use/d win on this pc be prepared to face a lot of problems that in some cases MAY require v drastic measures to reestablish the pc to a healthy state.

Can you help with this problem?
