If you had a backup made with Win 7 you may be able to use the Win 10 restore to restore that backup. However, I doubt that Win 10 can restore files from a WD backup.
Western Digital needs to become aware of that. There’s no point providing a backup utility geared at WD drives when the market today required backup programs that can make a disk image.
Mind you, a disk image won’t help if it is made for Win 7 and you want to restore to Win 10. The restore would write all over the W10 installation.
To summarize, if the old laptop is running a different OS than the new laptop there’s no way to transfer data and files easily. Data files can be transferred once you install the related application onto a newer OS.
One solution if the old laptop was running Win 7 would be to make a disk image of the old laptop drive using W7 backup. Then you’d restore the image onto the new laptop which would then be running W7. If you had a W10 installation disk you could then upgrade to W10.
You have to be careful. Most laptops come with a hidden partition that contains their related OS files. Using computer management in Windows you can unhide that partition to see what’s on there. However, if you keep it hidden you can usually restore a disk image from another laptop on drive C:
Alternately, you could upgrade your old laptop to W10 then make a disk image. You could restore that Image onto a new laptop.
This gets messy since most new laptops might come with W10 pre-installed. Since it’s a brand new install there’s no loss in deleting it or restoring a disk image from an old laptop over top of it. Might be better to format the drive first then do the disk image restore.
Gets even messier. Many modern drives don’t use stock formatting. You need to find out first what kind of formatting is used. There are ways to convert between the formatting styles and it’s not that hard if you’re willing to do some research.
