I am unable to get my T420S to boot from my Cloud Ready USB stick. I have booted from this USB stick successfully on Thinkpad X220. My T420S is i7, both UEFI and Legacy enabled, Legacy first.
When I try to boot, i am returned to the boot menu as if there is no detectable system on the USB stick.
Thank you in advance for any thoughts or suggestions.
I'd remake your USB installer and try again.
Also, make sure Secure-boot is turned off in your BIOS and of course that USB-boot is enabled.
After tweaking some settings in my BIOS I am able to boot from USB successfully. I'm not sure which one was the issue, but was tweaking the UEFI and Legacy booting options.
Thank you for the quick reply
