How to re-install windows 7 when nothing boots (incl. Safe Mode)

[oasis]

Dear all,

After installing (and having uninstalled) several programs, my Lenovo G560 4GB RAM, Intel I3 core, Windows 7 Home doesn't boot anymore.

Safe mode was working until yesterday which allowed me to back up all my files and I'm ready to completely re-install Windows.

But now Safe Mode won't boot anymore either.

Can anyone please help/tell me if and how I can re-install windows without being able to access Safe Mode?

There is a 2nd hard drive in My Computer I remember with all the drivers. I did not receive any CD/DVD-rom upon purchase of my laptop.

I used to have only Avast, Microsoft Security Essentials and Lavasoft Adaware as AV/anti malware. (all 3 uninstalled now)

I noticed the words/files trojan, backdoor and a file called something like misleading.trojan [?] during a running scan (possible a scan from Advanced System Care), these files were being scanned but no threat was detected.
Because I wanted to detect and delete these, I tried to download other AV software.

Since despite these files showing in a scan everything was working fine I should never have touched anything!!

The programs I installed when my Windows 7 was still working fine were all from CNET which is why I trusted them:
Because of compatibility I had do uninstall some AV and in the end I uninstalled (and hopefully cleaned the traces with CCleaner) some of the programs I tried as well.

These are the programs I installed from CNET over the last week:

- Avira Anti Virus (uninstalled now)
- Glary utilities (uninstalled now)
- Spybot search and destroy (uninstalled now)
- Trojan Guarder (uninstalled now)

- Objectdock (dock like in MAC but for windows, as a nice taskbar)
- UMplayer
- Smartdefrag
- Belarc Advisor
- Winstat (little program showing how you use your hard drive)
- AVG Anti Virus
- Malawarebytes
- Advanced System Care
- CCleaner (with which I deleted files from the registry that CCleaner said were faulty but added them all back (from the saved backups) to the registry later when my laptop starting slowing down, not working properly)

I now cannot:

- boot Windows 7 (stuck at windows logo)
- Safe Mode won't boot (last loaded driver AVGD...)

Really want to re-install Windows. Can somebody let me know if this is possible from the first LENOVO boot selection menu (F12)?
