Booting From Acronis CD into Windows 10 with UEFI
I need help configuring the UEFI settings to permit me to boot from my Acronis 2019 TI boot CD to restore the image of my hard drive to my Dell Precision 7750 laptop running 64 bit Windows 10 Professional.
Windows crashed when I tried to do a system restore. I cannot boot into windows or safe mode. Whenever I boot I get a BSOD. I have my hard drive backed to a tib file on an external USB drive. But I cannot boot from my Acronis 2019 TI boot CD. I never had this problem with Windows 7 or XP. And I never knew anything about UEFI until now. It seems that UEFI only allows booting from an internal drive or from a Dell Recovery CD.
I don't want to wipe out my hard drive and go back to a factory restore. But I don't know how to boot into Windows 10 from a CD on an external drive when the OS is using UEFI. Can I safely disable UEFI, then boot from the CD and if TI restores the image, would the restored HD have UEFI automatically enabled?

Thanks, Steve,
I sent a response to you a few hours ago but it has not yest shown up on the forum. If this post gets posted I will recreate my earlier post.
The F12 boot options do not include a cd/dvd or usb option. It appears that the only options under Dell Secure Boot are internal. In July I made 3 TI 2019 boot cd's from TI on my computer. The boot disks worked then from my external cd/dvd drive. Is there a way I can boot from TI?

Ronald, if your boot CD's worked back in July when you tested them from your external drive, then they should still work now. The key with any boot media is to have the drive connected before restarting the system so that it gets offered as a boot choice.
If you still don't see a boot option, then you may need to check the BIOS settings to ensure that the option to boot from CD/DVD hasn't been disabled in some way? The manual for your laptop shows that there are settings for USB configuration which are normally enabled by default that:
Allows you to enable or disable the internal or integrated USB configuration.
The options are:
- Enable USB Boot Support
- Enable External USB Port
By default, all the options are enabled.
