Bitlocker with a usb flash drive??

My wife want her laptop locked down with bitlocker and a usb flash stick(laptop does not support TPM) Never used bitlocker before and i don't want to brick the system and have to reinstall.

She has one physical drive split into 2 partitions, my question is can i bitlock both drives and use the same(one) flash drive as the keyholder to unlock the windows drive as well as the second partition(she does not want to have to input a password{lazy}?

Have looked but can't seem to find the answer, I know i can store the recovery key on the same stick, but since i dont know how the actual unlock key is written to the usb stick I don't want to encrypt the win drive with a key and then have that overwritten with the key for the second partition.

Hello Ba5ik,

Yes, you can save both recovery keys onto the same USB flash drive without any issue. Just keep a backup of both of them in separate folders on the USB flash drive as well to be safe.

For Windows 7 partition:
BitLocker Drive Encryption - Windows 7 Drive - Turn On or Off with no TPM

For other nonsystem partition:
BitLocker Drive Encryption - Internal Data Hard Drives - Turn On or Off

Hope this helps,
Shawn

thanks for the reply Brink, however I am wondering about the actual key not the recovery key file. Having bitlocked my own laptop(one partition) I have a usb stick with a *.BEK as well as the recovery key text file. My concern is if the .BEK file can only be stored alone, or if one usb stick can hold multiple .BEK files for different drives.

No problem. As long as the .BFK files have different file names, they can all be stored on one drive/USB key.
