Again, I have never done this, so IвЂ™m not sure exactly what would happen. You may have to reconfigure the boot options if you enable and then disable legacy boot without reinstalling Windows.

If you have to reinstall Windows, make sure you disable legacy boot beforehand, so that it does not install in MBR/BIOS mode. The safest solution would probably be to create a USB Linux installation that uses a Microsoft signed shim bootloader to boot without disabling secure boot, but this is a fairly complex process.Д«arring that, if you could find a way to disable secure boot without enabling legacy boot mode, that should be safe and would allow you to boot Linux off a USB drive.ДЄ third option is to both disable secure boot and enable legacy boot, which should allow you to boot off a USB drive. I have never used this option, so I canвЂ™t say much more than this.

If you enable legacy boot, nothing should happen to the data on the disk, but you wonвЂ™t be able to boot an EFI executable, and therefore it would be impossible for Windows to boot without being reinstalled in BIOS mode. This will make the computer try to boot using a MBR, like computers did before UEFI existed. On the other hand, the option in your computerвЂ™s BIOS appears to not only disable secure boot, but also enable legacy boot mode. In the process, I have disabled and enabled secure boot multiple times without any problems.

I have a Dell Inspiron i7559, which is likely fairly similar to your computer, and I have configured it to use secure boot with custom keys to dual boot Windows 10 and Linux. In my experience, nothing bad happens when you disable secure boot. So my question is, are there any gurus out there who have personal experience with turning UEF off so you can boot removable media? Is it safe to do? Are there any precautions I should be aware of? I donвЂ™t trust Microsoft. Having never dealt with UEFI Secure Boot before, I want to proceed very cautiously since itвЂ™s not my machine. When I press F2 on power-up to get into the BIOS, there is an option to вЂњChange BOOT modeвЂќ to вЂњLegacy Boot Mode, Secure Boot OffвЂќвЂ¦ but when I select that I get an ominous warning that it might make the disk unreadable. This machine has вЂњUEFI secure bootвЂќ enabled in the BIOS. In the past, IвЂ™ve used this technique successfully to make a hard disk usable long enough to recover files. If so, I would boot SeaGateвЂ™s SeaTools software, which on past occasions has successfully recovered seemingly unusable hard disks (by forcing the diskвЂ™s microcontroller to re-map bad sectors). If I had trouble accessing the disk, I would query the diskвЂ™s microcontroller with smartctl to find out if thereвЂ™s a disk error causing the problem. Once the files were safely copied to external media, IвЂ™d try fixing the O/S, or, as a last resort, re-installing from the factory partition.

I would simply boot Linux from a USB pen drive and copy the files to an external USB hard drive.
