I made a big mistake when installed Windows8 trial version to my G460. And now I want to restore the factory settings. I know it can be done with OKR but it's not competible with Windows8 and hence won't work.
Can anyone please guide me to get rid of this windows8?
Thousand thanks in advance

I understand you installed Windows 8 preview and now want to revert to the pre-installed Windows 7
Once the partition structure gets modified the hard disk recovery corrupts, if you have created the recovery disc then you can use them and restore the Operating System.
Please try running OneKey Recovery from hard disk. Power off the laptop then press Nova ( Rescue key ) instead of pressing power button and check if it works.
If OneKey Recovery do not work and you do not have the recovery disc then you can purchase the recovery disc from service center.
Please contact the support center to get the details on purchasing the recovery disc.

I discovered, with the help of Google and Bing, that this is pretty much a universal problem, but I couldn’t find a solution anywhere. So, in case it might be of use, I’m providing here the details of how I solved it. It’s not a very elegant solution, but unfortunately I know of no other. It does involve editing the partition table, so USE IT AT YOUR OWN RISK. You can really get yourself in a mess if you screw up.
In order to access the laptop’s System Recovery software, I set the recovery partition to be the “active” partition. This means that it will automatically be loaded at startup, so don’t do it until you are absolutely sure you want to (and are ready to) restore to factory default settings. From the command prompt (type cmd in the start menu to find it), rundiskpart. You’ll get the following prompt:
Here, type “select disk 0” and press Enter. It will let you know disk 0 is now selected. Type “list partition” to get a list of partitions. You’re interested in the one whose type is “OEM,” in my case Partition 3. Select that partition with the command “select partition 3” substituting 3 with the appropriate partition number. Use the command “active” to mark this partition as the active partition. Now, once you reboot your computer, you’ll find yourself in the Recovery software. Below are the steps I took inside of DiskPart:
DISKPART> select disk 0
Disk 0 is now the selected disk.
DISKPART> list partition
Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 200 MB 1024 KB
Partition 2 Primary 254 GB 201 MB
Partition 0 Extended 28 GB 254 GB
Partition 4 Logical 28 GB 254 GB
Partition 3 OEM 14 GB 283 GB
DISKPART> select partition 3
Partition 3 is now the selected partition.
DiskPart marked the current partition as active.

I followed your direction, then when I restart my computer, it show "X:\Windows\System32>" I tried sevral helps online for this problem but didnt work, then I try to reverse what I have dont by starting over your way but inactive the partition 3. Now the problem is even worse, it show "Broadcom UNDI PXE-2.1 v11.4.0......" Now what can I do to save my computer? (((((((((

This worked perfect looks and smoothwith a 9.9 hirens cd you start the machine, you enter particions tools, choose fdisk it or go well, looking for the hidden and active partition, reboot after you turn the machine and must start the recovery, the recovery reboot to finish the machine and ready as it left the factory
mira esto me funciono perfecto y sin problemas
con un cd de hirens 9.9 inicias la maquina, entras a particions tools, en ella seleccionas fdisk o al go asi, buscas la particion oculta y la activas, despues te sales reinicias la maquina y debera iniciar el recovery, al terminar el recovery reinicias la maquina y listo como salio de fabrica
espero te sirva

I am also a victim of problems with many preloaded softwares and drivers in lenovo systems after windows 8 upgrade. One key recovery isn't working in windows 8. But, i found this option so that it would work for Windows 8.
This is a feature that was there in previous versions of windows also but in different location. this application is of a wizard type that shows u that directs u through some questions regarding the application. which are very easily understandable. Give a try with this and enjoy the older version applications with new OS.

I found myself in exactly the same boat as you. I managed to return to my original factory settings but it was probably a very longwinded way of doing it as I'm not very technical!
I 'borrowed' a copy of Windows 7 from my dad, installed it as a fresh installation (do not format any partitions during the install, leave everything as it is and install to the drive that has the OS on it, NOT your recovery partition). After this was up an running I was able to load One Key Recovery from my recovery partition which can easily be accessed from explorer and restore my pc to original Lenovo factory settings.
So it can be done but you'll need a copy of Windows 7 to install first.
