Question about Canonical Ltd. Ubuntu

1 Answer

Am pulling my hair out. I'm a newbie to Linux but keen to get into it. Installed 9.10 as a dual boot alongside XP and after problems with grub, which I have re-mounted, I get to the OS choice page. XP will boot but selecting Ubuntu gives message "error: no such device: ff8d45d5-52ee-4ed2-9aa7-58195b2ef28a Press any key to continue" which takes me back to choice page Any clues will be welcomed with open arms.

Backup, Repairing and Reinstalling GRUB

  • To make a backup a copy of the existing menu.lst file use: cp /boot/grub/menu.lst /boot/grub/menu.lst.oldYou can try re-installing the grub using the Ubuntu Live CD, in two different ways.

GUI
  1. Boot your computer up with Ubuntu CD
  2. Go through all the process until you reach "[!!!] Disk Partition"
  3. Select Manual Partition
  4. Mount your appropriate linux partions / /boot swap .....
  5. DO NOT FORMAT THEM.
  6. Finish the manual partition
  7. Say "Yes" when it asks you to save the changes
  8. It will give you errors saying that "the system couldn't install ....." after that
  9. Ignore them, keep select "continue" until you get back to the Ubuntu installation menu
  10. Jump to "Install Grub ...."
  11. Once it is finished, just restart your computer

I had linux when i bought my hp compaq presario laptop.Then I installed windows 7 on it.I had my windows for3 years and didn,t had a problem till now.I updated windows and then when it restarted the grub...


Sounds like you may have installed windows alongside of linux after linux had been installed. This is not usually advised. If this is the case your most likely seeing windows boot loader instead of grub. If you did in fact fully replace with windows then the update may have two installations of windows on it. Either way I would recommend backing up data on hard drive (use a live cd to view data) and format hard drive and re-install Windows and if you had/want linux as well, install that after windows. If you can give me a little more info I can help you more.

Can't factory restore with dual boot system.


I run Windows 7 and also sometimes Fedora 16, Backtrack 5 and Ubuntu. Problem with reinstalling windows is it will write over the GRUB loader and you wont have linux there anymore. You are meant to have Windows first then install linux afterwards so you have the option of both.

Backup any files that you need and reinstall Windows then reinstall Linux. Its too much effort and mucking around to do it the other way even though it can be done

I installed Ubunto 9.0 AND when it came up it said, GRUB LOAD,no such partition, then at a prompt it says,grub rescue.


If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu or whatever flavor of linux you prefer.
Here’s the quick and easy way to re-enable Grub.
1) Boot off the LiveCD
2) Open a Terminal and type in the following commands, noting that the first command will put you into the grub “prompt”, and the next 3 commands will be executed there. Also note that hd0,0 implies the first hard drive and the first partition on that drive, which is where you probably installed grub to during installation. If not, then adjust accordingly.
sudo grub
> root (hd0,0)
> setup (hd0)
> exit
Reboot (removing the livecd), and your boot menu should be back.

Only read below if Windows is now missing from the boot menu
If you installed Ubuntu before you installed Windows, then Ubuntu will not have anything in the grub configuration for Windows. This is where you’ll have to do a bit of manual editing to the grub boot menu file.
If you open the file /boot/grub/menu.lst with the following command:
sudo gedit /boot/grub/menu.lst
You’ll see a sample section for Windows, which you’ll want to uncomment and add to the boot menu list in whatever position you want it in. (uncomment by removing the #’s)
# title Windows 95/98/NT/2000
# root (hd0,0)
# makeactive
# chainloader +1
Note that you should also verify that hd0,0 is the correct location for Windows. If you had installed Windows on the 4th partition on the drive, then you should change it to (hd0,3)

Boot loader problem


I beleive that you are installed windows first and linux second,then dual booting will be configured automatically ,means linux will install the grub (boot loader)and configure it with what all Os u have.If your system is not booting and showing grub menu do one thing ,boot it from a linux cd and reinstall grub.

USB mouse won't work under XP in a dual boot Ubuntu GRUB 1.5


It has the latest mouse driver (logitech setpoint 4.0). Before installing Ubuntu the setup worked w/ SUSE/XP using GRUB dual boot. After installing Ubuntu XP does not see the usb mouse. Even Logitech setpoint does not have the mouse setup/configuration option. It appears that at boot it does not recognize the mouse or disables it. The BIOS has the usb keyboard and mouse enabled. Currently, I have two mices one for xp and either mouse will work under Ubuntu.

Where is Linux mbr file


There's nothing like the Linux MBR File. The option to boot to multiple operating systems is controlled by a software called as the "Boot-Loader".
Windows XP and Linux both have their versions of boot-loaders. The Bootloader that Windows XP uses is called the NTLDR, whereas Linux provides many bootloaders (prominent among them being "Grub" and "LILO").

>but Linux is shown in the manage option from the My Computer in Win XP 2.....
That is the control section of NTLDR. So from what I understand you shouldn't have a problem selecting the operating systems.

If you want the Linux bootloader taking control of the boot process, you can always install it.
All you need is a Linux CD and then run the setup for "Grub" or "LILO".

Information about installing Grub or LILO can be found easily on the internet.
