<p>I will take a look at this more when I get home... but, do you have the partition table as it was beforehand? If so, you can use sfdisk to re-create. Otherwise, we need to look at the EBRs in the extended area.</p>
<p>This is why I hate MBR partition tables, by the way.</p>
<p>You should try running a utility to detect the partition, but don't count on it working; assume all is lost and hope for the best. Since it is encrypted it will be hard if not impossible to detect.</p>

I am re-sending this because I don't think my last attempt at this<br>
post was successful. I apologize if you are receiving it twice.<br>
<br>
I got in a hurry when my laptop was booting. It dual boots Windows 7<br>
and Ubuntu 10.10. While<br>
booting I bumped the keyboard and I think it started a Windows<br>
Recovery partition. I waited and then exited when presented with that<br>
choice, now I get:<br>
'error: no such partition'<br>
grub rescue><br>
<br>
The ls command returns:<br>
(hd0) (hd0,msdos5) (hd0,msdos4) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)<br>
<br>
When I boot Ubuntu from a live USB and look at gparted I see:<br>
/dev/sdb1 ntfs PQMSERVICE 13 GiB diag<br>
/dev/sdb2 ntfs SYSTEM RESERVED 100 MiB boot<br>
/dev/sdb3 ntfs 94 GiB<br>
/dev/sdb4 extended 190 GiB<br>
unallocated unallocated 185 GiB<br>
/dev/sdb5 linux-swap 5.86 GiB<br>
<br>
I'm guessing my data is in the part marked unallocated. Here's my question:<br>
Since I installed Ubuntu with encryption, would I be better off trying<br>
to mount that partition and look for my data or<br>
would you suggest I try to recreate or resurrect grub and its associated table.<br>
<br>
Also, I'm looking at trying 'testdisk' but the instructions tell you<br>
to use the one for your OS. I did not see specific instructions for<br>
dual boot PCs. Does anyone have a relevant hint here?<br>
