Unable to detect USB-C device in Boot Menu

2021-02-23, 2:39 AM

I have been trying to boot from my Thunderbolt 3 USB-C port on my X1 Gen 8 ThinkPad.  But the PC does not see the drive in the boot menu.  I have tried to change BIOS settings but have had no luck so far.  I guess my first question does the X1 support USB-C in the BIOS.  Any help would be appreciated.

I take it this is a Carbon.  I don't have one but my X1 Yogas - gens 4 and 5 will boot from USB-C so I'd expect yours to.

 

What sort of external device and how was it prepared?

Have you tried selecting USB HDD ? or setting Network boot to USB HDD or Other HDD ? 

 

If it doesn't work, go to the "Security" tab, then select "Secure Boot" , set this to "Disabled" , go back to the "Startup" tab, and set "UEFI/Legacy Boot" to "Both" or "Legacy Mode"

 

Regards

Running a M.2 USB-C Lightning 3 device, At the moment it is just a simple drive format. which i should at least be able to see in boot menu.  I can plug in my standard USB 3 device and it shows up fine.

What format?  NTFS or FAT32 or ???  I need to check, but it's in the back of my head that if the external isn't UEFI bootable (fat32, an efi partition or folder) it won't show up if the boot mode is UEFI.  Andy maybe not in legacy mode either if it doesn't have an active partition.

 

Not certain of any of that....
