Unable to boot

[asoriaz]

Hi,

I have a dualboot with Ubuntu 10.10 and Win XP Home ed.
Yesterday I installed a bunch of new updates in Ubuntu. When I attempt to boot up, I'm able to choose between booting in windows or in linux. Windows works fine, but when I try to start Ubuntu, the computer restarts itself, and I get the bootmenu again.

(Did not use an installation-CD.)

Any suggestions?

- Thanks.

Is this a wubi install?

yes it's a wubi install. and as far as I understand, I can't run the bootinfoscript in windows, and my problem is that I can't boot into ubuntu at all. The computer simply restarts itself..

Thanks, the problem is as described in problem # 2, but the solutions doesn't cover my exact problem. I haven't upgraded from 10.04 to 10.10, or any other major upgrade. It was a couple of simple security fixes in an automatic upgrade. In desperation I tried to replace the wubildr file, but in vain..

Your best move would be to download the 10.10 ISO and load a thumb or burn a cd and boot it live, to run the bootscript, then post it in that link.

Boot script says there is a problem with your wubi root file. Normally you would run chkdsk on NTFS partitions and e2fsck on Linux ext2, ext3, or ext4 partitions. But wubi is a file with a ext4 structure inside a NTFS partition.

I think you still can mount the root.disk and run e2fsck, but I do not know enough about wubi. Someone else should.

Hi asoriaz and welcome to the forums :-)

oldfred asked me to offer a possible solution, so here goes.

You need to do the following from a LiveCD or LiveUSB:


sudo mkdir /media/win
sudo mount /dev/sda1 /media/win
sudo fsck /media/win/ubuntu/disks/root.diskAfter running the fsck, try mounting the root.disk to see if it is accessible:


sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt

If you can access the root.disk, follow the rest of the instructions in the Megathread from the point of mounting the root.disk onwards; problem #2, solution #1.

This should get you booting Wubi again and then you can apply the Permanent Fix to prevent this happening again.

Thanks! Ubuntu is up and working perfectly! :D got a friend that had the same problem, and it worked for him as well.

[Rubi1200]

Excellent! Glad you (both) got it working again :-)

Please mark this thread Solved using the Thread Tools near the top of the page so that other users can also find a working solution.

Enjoy!

Hi! Not that I want to complicate things further, but I did a fresh install of Maverick (64-bit) two days ago and, after updating, I am not able to boot either (*-25 Kernel installed, btw). Is there anything one can do to revert updates? Say, go back to the systems's state two days ago and perform updates little by little, to see what the problem source could be?

[nico_demo]

ups, just wrote at the same time:-?. Since this thread is solved, I'll post somewhere else.
