Luckily I discovered that on updating to w 10 that one has to re - enable system restore. I did try it, but got an endless loop. Has anyone successfully used system restore in W10? Also I have usb recovery stick and a USB Iso. in a doomday scenario , how does one use these? Being cautious I also have a Macrium image and a recovery CD, and again do I just insert the CD- do I need to "tell" the BIOS the boot order? A bit worried on a young relative's pc I am setting up,as she sometimes leaves a film DVD in the DVD slot and I would not like a mishap!
Thank you. For system restore I just set it up as in W7, chose the C:/ drive (I use freefilesynch for backing up the other data partition.), then allocated 10% to system restore. Then I used the normal "Crete restore point" command.
I use CCleaner to delete old restore points and to edit start up as I find it more convenient. Thanks for the other suggestions.
Macrium, on first use, suggested I make a recovery CD.
Usually, today, DVD drive is first in boot order anyway if the laptop has an optical drive. If the CD/DVD left in the drive is not bootable (films etc.)then Windows will ignore it. If no optical drive on the laptop then USB will be first and again Windows will ignore a non bootable device.
