I bought a Yoga 720 – 15IKB (80X7003VUS) with:
.- BIOS InsydeH20 Rev. 5.0
.- BIOS version 4MCN15WW (v.1.01)
I’ve tried to find the way to change the boot mode from UEFI to LEGACY, but I couldn’t find it.
I disabled the Secure Boot, the OS optimized defaults, loaded the defaults setting, but after hours trying any combination, I wasn’t able to make the computer let me change the UEFI Boot mode. It’s a kind of “fixed option”.
Perhaps do I have to change from RAID to AHCI and afterwards move on with a system clear install?
Thanks in advance.
Solved! Go to Solution.

Thank you snake2332 for your answer.
I updated the BIOS a couple of weeks ago to 1.08, but still cannot change to Legacy. I even disabled the Secure Boot, but the option to change didn't appear.
Please, take a look at the photos below.
I'm far from been an expert, so, just guessing, could the UEFI-Legacy option be linked to the SATA Controller Mode? Did you change it to AHCI?
Thanks again for your help and collaboration.

The truth is that I changed the SATA Controller from RAID to AHCI after your answer. So, thank you for your confirmation. It worked perfect.
Just to check, I even "came back" from AHCI to RAID and the laptop did a recovery flawless.
I'd like to try to do a dual boot (W7-W10), although I'm pretty sure I'll have to wipe out all of the partitions, data and resident W10. Anyway, I'll search about it in this forum and others previously (drivers could be a problem, I guess). Maybe I could use a backup programm (like Easeus Todo Backup) just in case everything goes wrong.
But all this goes beyond this topic, that for me, it's resolved. Thanx again!

Were you all able to load the operating system and get to your desktop in legacy mode? After I change it to legacy mode, my laptop just sits there, restarts a few times, then eventully gets to to windows repair screen. I need to be in this mode to install the Windows 1803 update. Any ideas? Thank you.
