are certain USB sticks not bootable?
Posted: Tue 18 Oct 2011, 19:28
I have a couple of sticks that I'm trying to get 5.2.8 installed on.
One works and one doesn't work and I'm wondering what the difference is.
The working one is a 512mb Kingston... the failing one is a 2gb no-brand moody stick that seems to work as a regular drive with no issues.
When I boot, I see the initial syslinux line but then it hangs before the puppy splash screen. The light is flashing furiously at this point.
Here's how they both identify themselves
moody drive
Good drive
I tried dd'ing /dev/zero to the device to wipe out the MBR and the partition table and then ran thru the universal installer script but it made no difference
Just to confirm, the Kingston ones boots up perfectly, so I know the PC is set up OK and can boot off USB
