Comment 1 for bug 277903

I get a similar problem. After choosing USB Removable Media (or similar) as the bootable device I get "Invalid or damaged Bootable partition" (I don't know why the B is capitalized).

I ran usb-creator with and without -s and in both cases the end result was the same. I'm using the ubuntu-8.04.1-desktop-i386.iso and a new 4G usb memory stick:

$ sudo parted /dev/sdb print
Model: Kingston DataTraveler 2.0 (scsi)
Disk /dev/sdb: 4063MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
 1 4129kB 4063MB 4059MB primary fat32 boot, lba

$ df -h /media/KINGSTON/
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 3.8G 823M 3.0G 22% /media/KINGSTON

$ sudo fdisk -l /dev/sdb

Disk /dev/sdb: 4063 MB, 4063232000 bytes
5 heads, 32 sectors/track, 49600 cylinders
Units = cylinders of 160 * 512 = 81920 bytes
Disk identifier: 0x0008e42c

   Device Boot Start End Blocks Id System
/dev/sdb1 * 51 49600 3963968 c W95 FAT32 (LBA)

I don't know if it's interesting that the first 4MB of the disk is not being used. (well, actually it's the first 4,000 KB -- 50 cylinders * 81,920 bytes = 4,096,000 bytes)
