There are no Legacy BIOS options on the XPS 8940. Legacy options are ancient history now. [NAME]  - IPv4 and IPv6 boot options are used to boot the PC over a network using an OS that's actually stored on a server somewhere, rather than from files on an internal drive. IPv4 and v6 are just different types of internet protocols, but most PCs still use IPv4.  You don't change boot order in BIOS (UEFI) if you're trying to boot from a USB stick or CD/DVD. The bootable stick has to be plugged into the PC with power fully off. Or, the bootable CD/DVD has to be put into the drive and then PC powered fully off. Then power PC on and start tapping F12 to open the boot menu. Select the option to boot from USB (or optical disc) from the F12 boot menu. And if you decide to use Macrium, be sure to create its own USB boot stick too. Plug the Macrium USB into PC with power off and then boot and open the F12 menu. The image doesn't have to be on an external drive. I restored the SSD in my XPS 8930 earlier this week using a Macrium image stored on the internal 1T HDD, and it worked perfectly. There is a risk of storing backup images only on an internal HDD, should you get hit with malware or ransomeware that locks the entire PC down or if a HDD that's in regular daily use ever fails. So as added protection, you may also want to make a backup image every so often and save that one on an external HDD that's only used for backing up and otherwise, is not connected to the PC.
Hello all: SO----my xps8940 has a main solid state drive and a regular secondary drive. After I got the PC exactly how I wanted it----I created an image using the win7 backup and restore tooland also made a CD recovery disc. Win10 settings seems to indicate that that will work! I wanted to test it but I am having problems. I boot into recovery mode but am unable to find the image which is on the secondary drive.   With this PC----how do I change the boot order to boot  from dvd drive-----I have no idea. I get things like "use a device" with the choice of two different onboard nics (IPV4  and IPV6). I have no  ideas what that is and googling it just causes more questions.   I also tried the recovery flash drive I created  and also got  no where. On a 1-10 scale------I am a 5 when  it comes to win10. Win 7 was a lot easier with the old BIOS. Why does this system not provide an easier means of changing boot order which I guess I have to do----either boot from usb or in my situation boot from dvd.   I just want an easy way to make images and if necessary----use them for recovery when windows won't start .   Jeez----they  make this so difficult compared to win7.    HELP!!!!!!!
