Bitlocker key storage install

I am wondering if I can use the same usb stick that i store my bitlocker keys on to install ubuntu on. My Harddrive is completely Encrypted for Windows Bitlocker and In order to boot my computer I need my USB stick since I do not have a TPM supported machine. How would I go about installing ubuntu on my stick and still make it readable when called on by bitlocker? if this is even possible. Thank you in advance for any guidance and may peace be unto you.

If the stick was the only way I had to boot into the machine, I would take particular care not to corrupt it. I wouldn't try to put it to double use, no.

These little flash drives are so cheap, get one or two just for these odd jobs.

True that. I was thinking the same thing. thank you.
