Lubuntu Boot Fail

[mnewsome]

Launched Lubuntu from a USB drive successfully several times. This day I get an extended error log. Created an second Lubuntu USB boot drive and getting same type of errors. Lubuntu splash screen persists for several minutes followed by the error log which is uploaded to a Microsoft online folder at: https://skydrive.live.com/redir?resid=52B21D2F3F75A51A!2137

'hardware error'
'unrecovered readerror'
'buffer io error'

It is having trouble reading from your USB device.
Try a different USB drive or different USB port
