Therefore even you make Bootable flashdrive or CD it won't show up on boot menu or booting process.īackup all your necessary data to an External Disk Drive/Flash Drive/ or another Unit. UEFI has feature called safe boot which adds extra layer of security to loader and it prevent booting from external sources like bootable USB Drive or CD.

I ran into the same problem when I changed from Windows 10 (due to it's current flaw -the increased internet usage through background apps and system updates) to windows 7.Īlthough it is marked solved, I still taken the time to add my comment hoping to help future readers of this thread. Therefore installing windows 7 and lower OS that is BIOS Based and uses MBR disk partition takes some proper configuration to be successful. Windows 8 and higher OS uses UEFI mode and has GPT Disk Partition type by default.
