The solution is to download the excellent free utility Rufus, and use it to create the correctly configured USB disk. You'll get yourself in a bigger mess, and screw up Secure Boot and lower performance.

Ignore the other advice you may find online about switching to Legacy Modes and things of the such in the UEFI Settings. No other combination will work, and your shiny new Lenovo will happily and continuously ignore your USB drive at boot. But they, unlike many other vendors, very specifically need to boot from a USB disk formatted with a more obscure compatibility MBR Partition Scheme AND FAT32 file system. is that they use the newer (and now fairly common) UEFI instead of the old BIOS. The issue with booting from USB on Lenovo systems like Yoga 2 Pro, Yoga 3 Pro, etc. One of our systems even blue screened with INACESSIBLE_BOOT_DEVICE after attempting the upgrade.īy contrast, the Dell and HP systems we tried: smooth sailing. Even Microsoft's provided utilities to create a bootable USB to install from scratch failed on Lenovos. It was no surprise then when we went to install Windows 10 on multiple Lenovo systems that, of course, the normal utilities didn't work. Much of Microsoft's excellent work with Windows is undone by this consistently ignorant vendor, who is allegedly one of their biggest and best partners.
