If you have a Windows DVD, you can create an
ISO image with
IMGBurn in my signature. If you have a Windows 7 Home Edition Setup
ISO image file, you should create a Bootable USB Flash Drive or DVD with that. You do not want to boot from the same drive that has Emergency boot and the Clone Image on it as well. Using
https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool Or using
Rufus in my signature.
If you have a Clone
Image file on a USB HDD, you should create a Boot CD or USB Flash drive in the Clone software.
Starting with the rescue CD
Disaster can come in many ways. Your Windows install won't boot, your HDD has failed etc. Let's say the HDD failed, You would replace the old HDD with a new one. If you have a Clone Image file on a USB HDD, you would Boot off of the cloned software boot CD or USB and choose
Restore Image. With the USB HDD plugged in, you would browse it to the cloned Image file you created as your
Source. The
Destination or Target drive is the new HDD. Once that is finished you remove all USB drives and CD's and restart the computer and it should boot normally to the HDD with Windows and the files that were cloned on that day.
If you want to create 2 partitions on an External drive, If there are no files on the drive you want to keep, you don't need to shrink the partition. With the drive attached, go to Start/Search and type
diskmgmt.msc, Right click the
diskmgmt results and Run As Administrator. In the Elevated Disk Management window, right click the External drive and
Delete all partitions. Now right click the
Unallocated Space and choose to create a New
Simple Volume. Set the size of the partition you want, leaving enough space for another, Format NTFS. Then Right click the remaining space and do the same thing.
