Dual Booting Win7/Joli OS - no longer can boot to Joli OS after booting into Win7

I have tried some of the suggestions in the links provided with no success.  The boot directory, where the .mbr file resides, appears to be 'C:\jolicloud\winboot '.  This is the path I've entered in the EasyBCD software in the bottom link.  Now, when choosing the option at boot, the Windows Boot loader states the file is corrupt.  The next closest fix for my issue (without directly addressing a broken bootloader for jolicloud), is the section 'GRUB with Wubi'. However, no 'ubuntu' or 'vmlinuz' directory exists in order to follow the article.  I believe the answer is in this section but not sure how to adapt to my environment.  How should I adapt to a default installation of jolicloud?  I am determined to make this work, just need some additional guidance.  Thanks!

You can probably start the Joli from it's installation media which may have repair options. But as I stated I have never used Wubi myself. A reason is that it creates a virtual disk within your Windows File-System which holds the complete Linux installation. A file-system error of your Windows file-system can corrupt the complete virtual disk where Linux resides in.

If there is a file-system error you can try a chkdsk /x on all your windows drive-letters, that might repair such errors.

I ran chkdsk /x on all the windows drive-letters but still does not boot.  It doesn't seem like corruption - there was a clear difference (breakage) after booting into Windows 7.  I wrote Jolicloud tech support well over a week ago (4 days before posting here)but no response yet.  I even tried the recommendation at the following link, which is from Jolicloud site, but it did not work - acted like it didn't accept the command.  I typed it in several times to make sure it was correct but still no further.  see 'I can't boot Joli OS anymore. How can I access my files?' I also downloaded and ran a LIVE version off USB but there were no repair utilities that would help my situation.  I could try a 'reinstall' but am concerned it will simply overwrive this jolicloud virtual partition with a new one - essentially overwriting all my data.

I ran both the commands listed in the article 'I can't boot Joli OS anymore. How can I access my files?' by copy-n-pasting the commands, just to make sure I had not mis-typed.  At this point, if I cannot boot to the volume, I need to attempt to simply access/recover the data.  When entering the commands, the following output was seen in the terminal window. This is VERBATIM from the article.  What does this mean? Which is the problem - the volume which Jolicloud resides on or the folder just created by the command?  Some other issue, entirely? Thanks for your insight!

jolicloud@jolicloud:~$ sudo mkdir /media/je
jolicloud@jolicloud:~$ sudo mount -o loop /media/*/jolicloud/disks/root.disk /media/je
/media/*/jolicloud/disks/root.disk: No such file or directory
jolicloud@jolicloud:~$ sudo fsck -fd /media/*/jolicloud/disks/root.disk
fsck from util-linux-ng 2.17.2
e2fsck 1.41.11 (14-Mar-2010)
fsck.ext2: No such file or directory while trying to open /media/*/jolicloud/disks/root.disk

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

When you have the boot loader where you select either to boot to windows or joli, select joli and then press ESC. Do you get another boot menu with different ways of booting into JoliCloud? If so, what menu entries are there?

I tried your suggestion but the system simply rebooted (as if I pressed CTRL-ALT-DEL)

I think you must have pressed the ESC key too early, while you were still in the first boot menu where you select either Windows or Joli. Try again, but this time first select Joli and press enter, and after that press ESC. You should then have another boot menu that only shows your joli boot options.

As you recommended in your post, I was pressing ESC after selecting Joli OS.  However, after pressing, the screen immediately displays the error message stating that the OS cannot be found.  So, if I would have to be very quick to catch the 'in between'.  If I should see a another boot menu as you describe, I can only assume that something is broken or that ezBCD has taken over the boot process and does not accommodate the esc option. Installed it, per the 2nd link provided in the first reply post.  is there any way to check the consistency(error free)  of the volume or virtual partition that Joli exists within?  Just to understand if this volume is corrupt or insaccessible.  I am surprised that the commands Jolicloud support provide to access the volume do not work.  There may be some evidence in the output I included above but I am not very fluent in linux filesystem 'speak'

When you run

$ sudo mount -o loop /media/*/jolicloud/disks/root.disk /media/je

You should replace the joker (*) with a folder containing your data.

You can check what files/folders you have with the command

$ ls /media

did as requested and received the following output.  Why 'no suc file or directory'?  file folder check displays 'je'

jolicloud@jolicloud:~$ ls /media
3410C37A10C3419A  je
jolicloud@jolicloud:~$ sudo mount -o loop /media/je/jolicloud/disks/root.disk /media/je
/media/je/jolicloud/disks/root.disk: No such file or directory
jolicloud@jolicloud:~$

ok, that helped.  the command allowed me to identify the root.disk, mount, and copy important data out to USB drive.  I assume I will now need to reinstall the entire joli OS?

jolicloud@jolicloud:~$ find / -name root.disk -type f
/media/3410C37A10C3419A/found.000/dir0000.chk/root.disk
^C
jolicloud@jolicloud:~$ sudo mount -o loop /media/3410C37A10C3419A/found.000/dir0000.chk/root.disk /media/je
jolicloud@jolicloud:~$ 

Select allOpen in new window

Great! If you have all your data on separate disks I'd sugest a reinstall of Jolicloud!

Personally I'd suggest not to use the "Wubi (Windows)" installation, but rather the normal installation. That should give you the option to reduce the size of the Windows Partition and then install Joli to the free space created that way. It will then install the GRUB bootloader and add Windows to the selection. This installation method is more robust and also keeps to Linux standards better, and it can help should future problems arise, as more people know how to deal with standard installations.

I think this was the best solution.  It's unfortunate, with so many failed attempts, I was unable to boot back into Joli OS.  This would have been the best/quickest avenue 'back'. The good thing about Joli is that it's cloud based. so even when booting to the LIVE USB and logging in, all desktop settings were intact.  I will be researching how to install using performing a standard install, not WUBI.  Thanks very much for your assistance!
