BOOTMGR missing, any help on how to fix?

[liamhale]

hello guys,
spent a long time yesterday trying to sort my laptop out, i have ubuntu installed on my pc but previously my computer just loaded up a black screen with a white cursor, someone suggested it was the video driver, so i have downloaded onto a usb and i have got somewhat further, but now i have the error 'BOOTMGR is missing'
any chance of fixing this without wiping and reinstalling preferably on a usb stick?

thanks guys

I think you tried running the boot info script in your other thread earlier. We really need those results in this case to help troubleshoot.

If you need more instructions, follow the link in my signature which has the instructions how to run the script and post the results.

If your ubuntu boots you can do that from ubuntu, if not you can do it from ubuntu cd in live mode.

This is a windows message, that the boot file bootmgr is missing. Doesn't have much to do with ubuntu, something happened to your windows boot files.

i am a begginer at ubuntu, i am trying my hardest not to keep ask seemingly obvious questions, but i have downloaded the file and i have put it onto the ubuntu desktop, and typed the code sudo bash and almost every combination i can think of.

i have this code for certain: '/home/ubuntu/Desktop/boot_info_script.sh'

and i need sudo bash or just sudo


thanks again for helping me so much, i know i am not the most easiest of people to help as i am very much in the dark when it comes to the basics etc of ubuntu

Sometimes I am not 100% sure myself. :)

Also, at the end of the file name, before the extension, add * to replace any version number it might contain. So, try something like:


sudo bash /home/ubuntu/Desktop/boot_info_script*.shDon't forget, in linux desktop is not the same as Desktop. Type exactly as it says.

I finaly have it
thanks for the code, i was missing the asterisk, it is still beyond me why that was needed :P
i also managed to search for the results.txt file as i couldnt find that originally either

but these are the results:

Out of what ever reason, the grub2 bootloader never installed. Boot into live mode, open terminal and execute one by one these commands to enter inside your hdd installation and install grub2 (the package name is officially grub-pc):


sudo mount /dev/sda1 /mnt
sudo mount --bind /proc /mnt/proc
sudo mount --bind /dev /mnt/dev
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt

I am breaking them down to be easier to view, you just keep executing line by line:

apt-get install grub-pc
grub-mkconfig
update-grub
grub-install /dev/sda


exit
sudo umount /mnt/sys
sudo umount /mnt/dev
sudo umount /mnt/proc
sudo umount /mnt

If during execution some error shows up, make sure you typed the command correctly. If yes, stop executing the commands and tell us exactly the error message and after which command it showed up.

If you finish all of the above without errors, restart and hopefully ubuntu will boot.

sorry, i donot understand what it is i need to do, i have these codes, and i am currently running the live version of ubuntu, and i have terminal open. what is it i am copying and pasting one at a time and do i need any other codes that i need every time or is is just a case of copying one line then entering and then do that for the other 4 or so. if so what are the other simplfied code box's for?

sorry to be a pain, iam sure you will be glad to get rid of me :P

[liamhale]

i have managed to work out the way in wich you meant
ist box - paste all at once
2nd box - paste line by line
3rd box - paste all at once

but, i have carried this out and terminal closed itslef after last chunck of codes, and i have restarted without my hard drive and the same has happened, i have not seen any errors when terminal was executing the codes either :(
would you like me to run the boot manager again?

[darkod]

No, don't copy-paste. I think it can't work that way.

You need to type it line by line in terminal hitting Enter after each line. It needs the Enter, that's why you can't copy paste. It's not that much to type.

I also noticed another thing just now, you seem to be missing the kernel file which is the main file, so the above instructions might not work 100%, but do them anyway and later we will see if we can do something about the kernel file.

It's like the install never finished so the kernel file is missing and the bootloader never got installed.

I am wondering if it's better to simply reinstall again. It would be best if you use the manual install method, not one of the automatic ones but you don't seem to be experienced enough for it. If you can handle it, installing manually is always best because it gives you total control and in your case you are installing from a usb hdd if I understand correctly, which might be confusing the installed additionally.

Another idea is to try using a cd or usb stick if possible, but not usb hdd.

okay i will try the writing of codes in now,
i did have a slight error, at the end of the installation it said something about a cd/dvd at the end, but i thought this was because i didnt have a cd or dvd in the disc drive it couldnt add any extra material that i assumed wasnt needed

[umitarabul]

Maybe, you also forgot a USB disk plugged, as I did. Check your boot sequence and remove any USB :)
