Experimenting with ESXi5, I accidentally got a GPT formatted USB stick that no XP systems could handle.
I used Convert GPT Disk to MBR Disk – Windows 7 Forums to convert it back to MBR.
I needed to perform these DiskPart steps on a Windows 7 machine, as
- the disk management UI in Windows 7 wouldn’t list “convert to MBR” (probably it shows this option only on non-removable media)
- the DiskPart Windows XP doesn’t recognize GPT (should have been obvious to me, but still)
