I am struggling with this...I have somehow wasted the one opportunity to make recovery disks, and I want to restore the PC to original factory state.
It came with preinstalled win 7, and upgrade disks for windows 8.
No recovery media were given for win seven, I want to achieve two things>
1. get the machine to original state
2. generate new DVD disks for total win 7 recovery, from the q recovery partition.
I am pasting a good tutorial on this:

Finally, i tried this option and it works.
If you have data present in lenovo recovery partition intact, then go to Q:/lenovo_recovery/factoryrecovery/ and try to locate two files cdrivebackup.wim and sdrivebackup.wim.
Detach the hard disk of your laptop and connect as a external hard disk to second laptop. Open Easus partition master software to create two partitions on your external hard disk. First is S:SYSTEM_DRIVE and second as Windows7_OS (no need to assign drive letter C: to second partition). Now use 7-zip software or powerISO software to extract the sdrivebackup.wim image to S:SYSTEM_DRIVE. Similarly, extract contents of cdrivebackup.wim image to Windows7_OS partition on external hard disk.
Now, disconnect your hard disk and re-connect it to your laptop hard-disk slot. Now use any windows7 installation disc (you may get lot of such .iso images from torrents) to boot into system. Eventually when system asks you to install windows7 into partitions, do not do anything. Simply press “Shift+F10″ to get a command prompt.
Once you get command prompt. Do following.
1) issue command “diskpart”
2) Issue command “list disk”
3) issue command “select disk 0″
4) issue command “list partition”
5) issue command “select partition
You can easily guess the partition by looking at the size of
partition “Windows7_OS”.
6) assign drive letter C: to that partition
7) Now issue command “active”
9) Restart your PC.
I hope this will help. I have another solution if you don’t have a second laptop or if you are not able to arrange a second laptop for your help.
Thanks
Abhishek

This tutorial worked excellently for me...I got to a state of Windows is setting up your computer for first use.
However, the installation / when first booting into the newly restored factory system/ failed.
