I have a quite annoying problem. Like an idiot, I used the recovery partition on my thinkpad to restore factory settings, but without making a recovery media first!
When I bought the computer, I separated the C: partition into an OS and data-partition, because that's what I'm used to.
The recovery seemed to do the job, until I tried to restart the computer. Then I realised, that there was nothing in the C: folder, while the other folders seemed to be unaffected.
Problem is, now when I try to boot into the recovery-partition, I get a winload missing-error. If I mount the drive on my other computer and browse it through easeus partition manager, all the files are still there, including the cdrivebackup.wim, but I can find no way to boot and install from the .wim-file.
Okay, so I solved the problem myself, a bit more crude than intended, but it works.
Here's the solution, if anyone else ends up with the same problem:
I took the harddrive out, and connected it to my other laptop with an esata cable
I then used easeus partition manager to remove my established Data-partition, resize the OS-partition to it's former size and format the whole partition.
When I tried to find the files on the Q:-drive, I couldn't see them, but could see the files through the "explore"-function in Partition Manager, so I copied the "cdrivebackup.wim"-file to the laptop through windows commandline.
Then I used 7-zip to extract the .wim-file to the OS-partition on the Lenovo harddrive, popped it back in the thinkpad, and voila, the computer booted, everything back to normal, and there has been no problems until now.
