make usb-drive unbootable

Start administrator's command prompt:

Open start menu
Type cmd
Press Ctrl+Shift+Enter
Fire up the utility called diskpart. Literally, enter diskpart command.

DISKPART> prompt should appear.

Now in diskpart prompt type: LIST DISK and it will list all your Disks including your USB drive. Note the Disk number.

Type the SELECT DISK <num>, where <num> is your USB disk number. Just look for right capacity of the drive.

List all partitions on it: LIST PARTITION.

For every one of them type: SELECT PARTITION <num>, where <num> is the number of partition and DELETE PARTITION.

Now check there aren't any of partitions left: LIST PARTITION. If there aren't any create one partition:

CREATE PARTITION PRIMARY - If it asks about size, just use the default value - it is the max capacity

FORMAT FS=FAT32 QUICK - I think USB flash drives use FAT32 filesystem by default. You could use NTFS instead too.

That's it!
