stanca,

Have you tried using the boot-flag
or Have you change your BIOS setting since your 10.7 install?

Do you still have your 10.7 install intact or do you have a backup to revert to?

I am not an advocate of pre-patched pirated copies. The same goes for automated patch/install applications. It is important to understand the workflow for install and which patched or new files are required. When you decide to update, you will have a better understanding of what it takes.

Your motherboard's spec sheet is a good start: http://www.asrock.com/mb/overview.as...&Model=H61M-VS
AsRock H61M-VS
BIOS: AMI UEFI
Chipset: Intel® H61
LAN: Atheros AR8152
Audio: VIA VT1705

I would consider starting from a clean download of Mountain Lion from the App store. Keep a clean copy as a backup and then work toward getting to the installer with the minimum required patches.
