I have a ThinkPad Gen2 T15p (its either a p or D, its super tiny).
My goal is to boot from a USB drive for an offline image. The BIOS does not an option for Legacy boot,
only Secure Boot off. The USB appears in the boot options menu but does nothing.
I have formatted it as NTFS. I tried Fat32 and it fails to complete because of the limits of Fat32 and exfat.
I created the image in MDT and then offline Media, moving the content to the USB as always.
Does anyone know either how to format the drive properly or set up the BIOS for the ThinkPad Gen2? I also tried
using 7-zip to add to archive the WIM file (4.9G), move the pieces over and then Extract those files. However, even on a
32GB drive it runs out of room.
Thanks in advance
Hi,
Per my experience, if the BIOS is set to UEFI, then you have to create your USB stick in UEFI bootable model. Please also make sure to turn off secure boot.

There is no way to set the BIOS to anything other than UEFI. I tried to format the USB to FAT32 but my actual wim is 4.9, where 4.0G is the limit of copying a file as FAT32. I used 7zip to Archive the file which split it into smaller pieces. I copied them over and then 7zipped again to extract it back to a WIM, and again ran out of room (using a 32G USB.
Leaving it NTFS with secure boot off, I can see the USB....clicking on it does nothing. I've made dozens of these for Dells and had no trouble booting to them. Not much info to be found for Lenovo, other than plug it in, boot to the boot option menu and select the USB. Well no kidding.
There must be some other requirement for booting to a USB with an image made in MDT, creating a Media file as I've done lots of times.
Hi,
Thanks for your reply.
1,You can try to use Rufus to build UEFI bootable USB media.
2,Please contact Lenovo to see if there is anything specific for ThinkPad Gen2 T15p.
Thanks for your time. Have a nice day!

Seeing how the Lenovo can only be set to UEFI and the Lenovo tech didn't have much to suggest...
I treated this laptop as I would a Hyper-V VM. I inserted the USB and went into the Deploy folder and launched the litetouch.vbs script and it rebooted to the usb and followed the task sequence all the way through.
That is how I will deal with offline Thinkpads from now on.
