Topic: [SOLVED] Live USB boot fails

I am trying to reformat a hard drive where I accidentally wiped out the boot partition a while ago.  I created two live USB drives, trying both the amd64 and i686 iso but everything fails.  The computer is a Dell Optiplex 7010 mini.  When booting from one USB, I get

isolinux.bin is missing or corrupt.  Selected boot device failed.  Press any key to reboot system.

I understand this can have several causes; so I ignored this USB and tried a second one. This one gives just

Selected boot device failed.  Press any key to reboot system.

I wrote both USB drives using

sudo dd if=gparted-live-1.3.1-1-amd64.iso of=/dev/sdc1

fdisk command gives different result depending on params:

$sudo fdisk -l /dev/sdc1

Disk /dev/sdc1: 4003 MB, 4003463168 bytes
64 heads, 32 sectors/track, 3818 cylinders, total 7819264 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x72148e31

     Device Boot      Start         End      Blocks   Id  System
/dev/sdc1p1   *          64      782335      391136   17  Hidden HPFS/NTFS

$sudo fdisk -l | tail

/dev/sdc1            2048     7821311     3909632    c  W95 FAT32 (LBA)

Anybody can help me out?

Re: [SOLVED] Live USB boot fails

I bought a new USB and created the Live USB again.  At first I was equally unsuccessful, but then I saw a message about the time not being an acceptable value.  I had never seen that before.  I plugged in the correct date and time.  After that, the live USB worked.


EDIT: this was not the only change.  I also changed the boot sequence to put the floppy at the bottom.  This PC does not seem to have a floppy.  Boot sequence did have the USB at the top already; so I doubt that change made any difference.
