Cannot start my computer

When I start my computer it usually goes to the Acronis OS selector, I choose my OS and it starts. Now when my computer goes to OS selector I get an error saying that Acronis cannot find the files needed and I need to reinstall it and my computer shuts down. Is there any way I can disable Acronis OS selector so I can access Windows and reinstall it?

*edit - the error I get is - Error 1 - Cannot find necessary configuation files, please reinstall Acronis OS Selector.

I get an option to choose OK, after I click it my computer shuts down. I don't have access to my computer now because of this, is there anything I can do?

 

Try; Boot from rescue CD, click on activate OSS, leave the CD in, ignoring the incorrect message to remove the CD. Hopefully you'll boot back into Windows. If not reboot using the CD and then click on continue booting Windows.

Once in then you can remove OSS if you want to.
