    Question GNU GRUB on startup, no CD

    I got the same problem and I don't seem to be able to resolve this because my CD ROM is dysfunctional so I cannot do a wipe and reinstall. I put Ubuntu using PLOP manager when I had Windows XP... I then overwrite the Windows XP with Ubuntu.

    None of the above solution would work because I cannot get pass GRUB GNU screen.

    Is there anyway out of this?

    Moved to your own thread.

    You really have to have a way to boot externally, either CD or flash drive to make repairs.

    If you get a grub rescue prompt, you should be able to manually boot.

    If computer does not boot from USB, then you need to repair or replace CD drive. Sometimes it may just need cleaning? Or check connections.

    Yes I did try the Grub Rescue thread, it does not work and I don't know why mine looks like (hd0) (hd0,msdos5) (hd0,msdos1)...

    They have added msdos to tell it apart from the newer gpt. My gpt drive looks like (hd0), (hd0,gpt1).

    Two choices, new CD or maybe you can remove drive, and plug into another system as an external or even internal drive. Then you can make repairs.

    Okay, I bought a replacement CD drive, what is the next step? I tried to wipe out Ubuntu altogether with my original Windows XP recovery CD, but I got Error #1826 Free space not found

    Yes Windows does NOT work on ext4/Linux partitions. Download and burn a fresh Ubuntu.iso (burn at the lowest possible speed), if you don't already have Ubuntu LiveCD/DVD. Boot with it and opt for "Try Ubuntu", once the Desktop is ready Back Up and rescue any DATA that you want to. Then open and run GPARTED, using which you can repartition your HDD accordingly.

    From the desktop icon "Install ubuntu" install your Ubuntu and at the appropriate screen choose "Something Else" option to manually set your install target partition on HDD. More Info Here. Or you can just Install ubuntu with default install method.

    Re: GNU GRUB on startup, no CD

    Thanks for the above reply, I will try to get a LiveCD with 12.04.2 LTS, I am guessing it does not matter even though I installed 12.10 originally?

    The part I am unsure about is this: "
    Then open and run GPARTED, using which you can repartition your HDD accordingly", is there a step by step guide somewhere for reinstalling Windows XP?


    My Windows XP CD is just a recovery disk rather than a full installation CD, I don't know if that would change the situation somewhat?


    Sorry about all these questions...

    Please stop perpetuating this long worn out myth. Modern CD burners will actually produce a worst result by doing this.

    It you're concerned about getting the disc burnt correctly, turn on write verification. Any decent CD writing software has that.

    I have a relatively new CD/DVD burner (2010-11) and at times it does create problems if I burn, especially, OS and other Software at the burner's optimal speed, in spite of enabling 'verification'. I have also seen this happening on "Newer" Burners. "Bad Burn" at optimal speed is a possibility even with the best of Burners out there. Its not yet, a myth; at least NOT in my personal experience. Also until now I haven't seen any adverse effects by burning at slowest possible speeds.
    Burning at the 'slowest possible speed' is the pre-caution I take when burning an OS.

    However, I haven't faced any issues with Data burning at Max. speeds.

    Thanks for the Links.

    You're welcome for the links.

    FYI, all CD's & DVD's are just data, no matter what that data really is.

    Bottom line is that there is never a good reason to burn at the "lowest possible speed". At "not the highest speed", maybe. If anything, burn at half the highest speed, that will give better results than the "lowest possible speed".
