My laptop is an HP Pavilion Entertainment PC and my OS is Vista Home Premium
Version 6.0 Build 6000. I haven't been able to install SP1.

I've done a mirror image of Drive C on an external HD by Acronis. Acronis
offers the option of accessing Startup Recovery (through F11) if the OS
fails to boot. Is there any danger of a conflict between this and Vista's
own startup repair system?

Second question: F8 brings up a choice of options, including a system
repair. This accesses a new menu of options, one of which is a restore from
an external source. Presumably this means a mirror image. Will ANY mirror
image work with this?

Thanks for your help.
