I've got a 4GB USB flash drive and am trying to partition it. I'd like 2GB to be an OS (ChromeOS by Hexxeh), and the rest should be one FAT32 partition.

  • Windows should recognize the FAT32 partition.
  • My BIOS should recognize the other as bootable.

Windows partition manager seems to allow you to make a partition if a partition already exists. Anyone know how I can do this?

  • Once you've done this, how do you "eject" the drive to make sure all the data has been written to the drive before you remove it? I'm assuming without the removable bit set the drive will not offer the option to eject the media. – David Smith Feb 18 '10 at 20:56
  • Is this true to all flash drives?Because I tried it on my 8gb toshiba and it doesnt work. What would be the recommended size of usb? – Wern Ancheta Feb 18 '10 at 22:52

  • Anyone know of a tool that'll flip the removable bit on a SanDisk Cruzer? The Lexar BootIt app doesn't work. –  Feb 19 '10 at 02:44
  • @AMWJ - flipping the Removable Media Bit on the device descriptor of a SanDisk Cruzer is not possible, sorry. –  Feb 19 '10 at 03:02

The fat32 partition must be the first partition on the device or windows will not mount it.

  • And you downvote for that??? – r0ca Feb 18 '10 at 20:25
  • I also see no indication on the website that it works with a USB flash drive, didn't work with my big flash drive or the two generic ones on my desk either. You gave a bad answer, so yes that is a downvote kid-o – Urda Feb 18 '10 at 20:27
  • It doesn't recognize my USB. –  Feb 19 '10 at 03:06
