dual boot ubuntu 12.04 / win7, ubuntu does not boot anymore, boot-repair paste file

[ronny-de-winter]

Tried to recover with boot-repair without result: paste file: http://paste.ubuntu.com/6889930/ (http://pasete.ubuntu.com/6889930/)

Can somebody help?
What can I do? Is there still hope for recovery?
Is there a way to recover files from the ubuntu system with a recovery linux on usb for example?

The link you gave contains a typo I guess this is the right report: http://paste.ubuntu.com/6889930/

Looks like a complex situation as you use Wubi. If you have a linux usb you might try the following:
https://wiki.ubuntu.com/WubiGuide#How_can_I_access_my_Wubi_install_and_rep air_my_install_if_it_won.27t_boot.3F

You can also try from Windows:

No luck so far:

Following the linux usb instructions:
$ sudo mkdir /win
$ sudo mount /dev/sda1 /win
$ sudo mkdir /vdisk
$ sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk
/win/ubuntu/disks/root.disk: No such file or directory
$ ls /win
AUTOEXEC.BAT CONFIG.SYS diags RAMDRIVE.SYS
AUTOEXEC.UP CONFIG.UP HIMEM.SYS
COMMAND.COM COPYUP.BAT oobedone.flg

Tried the windows tools as well, but they complain that I need to be administrator while am administrator ?!

Anybody some ideas what else I can try?

[ronny-de-winter]

ok I had the wrong sda, it was /dev/sda3
Now I can access my files. they are still intact.

However booted with an ubuntu live cd I cannot copy them to somewhere else. PC has no cdrom drive. How can I move the files to a save place?

Can I reinstall wubi and leaving my ubuntu homedir in tact?

All of wubi is in root.disk. So if you just reinstall, it creates a new root.disk. You may be able to separately backup the data. But at this point if you want Ubuntu it may be time for a fully partitioned install. Wubi is more for an extended trial to see if you like it and easy uninstall, not long term use.

From the developer of wubi:
http://howsoftwareisbuilt.com/2009/03/12/interview-with-agostino-russo-wubi-ubuntu/

Agostino: Wubi actually wasn’t designed to do long-term installations. The main aim was really to let people try out Ubuntu with confidence. Normally, users that start with Wubi tend to upgrade to a full installation to a dedicated partition at the next release cycle.
