I have an existing internal 80gb hard drive I added a new usb2 external 160gb hard drive to my pc. I plugged it in and partitioned it into 90gb and 65gb. The first being primary K drive and the second logical L drive – is that correct. I then used Acronis true image to add a secure zone of 30 gb within this first primary partition K. The idea being was to back up the C drive on my existing 80gb internal hard drive (divided into 30gb primary partition for operating system and programs and second logical partition for doing video editing in) onto the new K drive secure zone. Then to activate start-up recovery manager which allows you to boot using the F11 key in the event of windows not booting up. This allows you to start acronis and then use the image of the operating system on the K drive to start up a clean version. It may be that because I did not copy the image across first that before I activated the start up recovery manager it came up with an error in acronis – since in reality there was no image of the O/S there. When I later booted up windows my pc would not work but as soon as i switched off my external hard drive then it booted up ok. It looks like its trying to boot from my external drive. I have tried to change bios but still not working. I started again and this time made two logical partitions and put the secure zone in one. I copied my c drive into the secure zone no problem. But when i went to switch on restore manager it says that i cannot do it from this drive even although it will not let me choose the drive. And of course the pc will not boot. Can anyone take me through the steps monkey fashion as i am totally baffled and so are the non acronis users on another forum i use.
