How to boot a partition from Windows Repair CD?

[DarkLightA]

I've got a Windows Vista and Win7 PC, originally Vista. I've got both CD's. I've installed Acronics OS Selector, a boot manager, just installed and it won't load when it starts up...    So I'm left with a computer that isn't booting.

Is there a way I can disable this program and therefore uninstall it when in the PC, or boot Win7 from the Repair disk?

Try running the repair disc and see if that will fix the problem by its self. i recommend using easybcd for your boot selector/manager
