I'm currently on my 2nd SanDisk Extreme USB 32GB as the first one turned out to be a fixed disk rather than a removable one, so I purchased another hoping it would be removable which it was. Unfortuantely I cannot for the life of me get the device to be reconized as a boot device (or even just regonized in the BIOS) on my X220T and T420 Lenovo laptops. I have a trancend USB and SanDisk Ultra 32GB USB which both work just fine. Can anyone help me with this?

I Think this may help you. I never thought to change the boot order of the HD's. http://www.tomshardware.com/forum/329871-30-bootable-windows-install-stick-detected-boot-device Good Luck !

Re: Ed I tried partitioning, using automated tools such as Windows USB tool, tools I've seen you recommend for linux, pendrivelinux, Ubuntu whole disk installer etc. Nothing seems to get it appearing on either the X220T or the T420 Lenovo. Unfortuantely the only other deivce I have is a Surface Pro so I cant check if it's compaitable with other machines.
Re: Newatthis. I don't arrange the boot order cause I'm going straight to the boot menu options and the drive doesn't appear on the list (and subsequently wont be affected by boot priority)

Hi, same problem here
Laptop : t520
Stick: Sandisk Extreme 16 GB
Disk is not visible in boot menu. I have tried USB drive from different vendor, all working. I have tried the disk with different laptop, all booted correctly. I have found many users with this problem(sandisk + thinkpad).
I have tried to complete repartion the drive using diskpart, main partition is FAT32 and active. The "Boot Disk" flag is set to "no", but my other flash drive is also set to "no" and it is working just fine.
Is there a possiblity there is some hidden partition windows is not able to see ? I heard windows systems are sometime having a hard time working with multiple partitions on a flash drive
