Help needed restoring factory state on X220!

[indotoonster]

Hi there,

I just bought a 2nd hand X220. The seller advertised it as having its recovery partition intact (when I remove the battery there is a license/COA sticker for Windows 7 Pro), unfortunately the previous owner installed a copy of Windows 7 Ultimate on it (which I believe might actually be a non-genuine copy).

However, I can see the Lenovo_Recovery drive in Windows Explorer, it shows up as drive E: and has the following files (all hidden): LenovoQDrive application along with the FactoryRecovery partition containing bcdinfo.txt, cdrivebackup.wim, RECOVERY.INI and sdrivebackup.wim.

Previously when I pressed the ThinkVantage button on startup, it would show me the menu to go to BIOS setup (F1) or choose different boot device (F12), but no F11 option.

I read about the Recovery Repair Diskette, but also found a page saying that this doesn't apply to Windows 7 machines anymore, and that I should just install the latest Lenovo Rescue and Recovery. So I have now downloaded and installed Lenovo Rescue and Recovery 4.50, but now when I press the ThinkVantage button or F11 upon boot-up, it briefly says something like "launching recovery application..." but then proceeds to boot into WIndows 7...

Can someone please help me restore the factory state?

Many thanks in advance!!

BTW, some more info:

1. The Lenovo_Recovery drive shows up as E:, which is quite puzzling as some forum posts mention a Q: and S: drive, both of which don't appear for me.

2. Lastly, I suspect there might be a virus, because all drives have very dodgy looking autorun.inf and .pif files Restoring to factory state will not carry over a virus infection, right?

Thanks in advance!
