Updating windows without a cd
If you’re going to upgrade to Windows 10 for whatever reason, an existing system, Windows 7, Windows 8, being upgraded to Windows 10, then by all means take that image backup first but that’s something you should do regardless.Always take an image backup of the machine prior to upgrading to Windows 10, regardless of whether or not you think it’s going to work because about the time you assume that it’s going to work, it will fail in some way and you’re going to want to go back.Either you’re happy with Windows 10 and move forward, or you’re unhappy and it doesn’t work and you simply roll back by restoring that image backup of data, ideally kept in a different location than the original.If there’s only one copy of something – say a photograph on a mobile phone – then it’s not backed up.When restored, the files are replaced on the hard disk, but not necessarily in the same physical locations as they were originally.(One positive side effect is that often a restored hard disk has no fragmentation.)The second, when restored, places all files in exactly the same physical location as the original and restores all unused sectors as well, thus enabling deleted-file data recovery and potentially other forensic techniques.
Computers are excellent at making copies of digital data, and backups are one important use of that functionality.
Is it time to update my recommendation for Windows 10? It’s the middle of November, 2015 and as I speak, Microsoft is apparently in the process of rolling out a fairly major update to Windows 10. The initial reports haven’t started coming in yet, but since I’ve been promising an update every couple of months or so with respect to my recommendation on what you do with Windows 10, I thought I’d take this opportunity (while they’re updating the software) for me to update my recommendation.
Let’s take a look at what the results might be when you update your Windows 7 or Windows 8 machine to Windows 10.
An image of a hard disk refers to a copy of all files, folders, and overhead information stored on the disk, including the information required to boot.
Another definition used less frequently is that an image is a copy of every sector on the disk, , as well as their physical layout. An image by the first definition is all that is needed for backup purposes.
