[Bug 458482] Re: usb drives imaged with usb-creator fail to boot on some systems

[chud]

Bug also effects D965GF Intel boards (Still in Natty 11.04 startup disk
creator)

However there is a solution and it is because of 'faulty' FAT32 boot sector, the offending bits to fix are offset (from boot sector start)
1A h (Number of Heads) [this as always been correct in the things ive looked at, but its something to check, 255 heads = FF in below example ]
1C h (Number of Hidden Sectors in Partition) [in below example is 2048 = 80 00, when wrong usually 00 00]
40 h (Logical Drive Number of Partition) [should be 80, when wrong usually 00]

You can manually edit these or use ms-sys (http://ms-sys.sourceforge.net/) to fix by doing (assume usb stick is sdd)
./ms-sys -p /dev/sdd1
you will see something like

 ./ms-sys -p /dev/sdd1
Start sector 2048 (nr of hidden sectors) successfully written to /dev/sdd1
Physical disk drive id 0x80 (C:) successfully written to /dev/sdd1
Number of heads (255) successfully written to /dev/sdd1

You can also use this to fix your own bootable sticks if you are
formatting with mkfs.vfat

Title:
  usb drives imaged with usb-creator fail to boot on some systems

Status in “usb-creator” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: usb-creator

  When using usb-creator-[gtk|kde] to image a drive, some systems will
  fail to boot unless the system bios is set to "USB Mass Storage
  Emulation Type" to "All Fixed Disc" from "Auto Detect".  This is
  reproducible on the following Intel boards: D945GCFL D945GCFL2,
  DP35DP, DQ33HS.  All systems have been verified to have the latest
  available bios from Intel.  Until this setting is made, the only
  message received is "Boot Error".

  This used to work with usb-creator for Jaunty.  I have retried images
  that worked with Jaunty (through Karmic Beta) to verify this is not an
  image issue.  This affects UNR, Moblin-remix, Desktop-i386, Desktop-
  amd64, and probably others as well.
