SQUASH FS Errors !
These errors can be due to a variety of reasons:
- bad memory modules (use memtest86+ to check your memory at boot menu)
- a corrupted iso image (solution: run an md5 checksum, and if they don't match, download the iso image again) (See https://help.ubuntu.com/community/HowToMD5SUM )
- bad usb drive/stick (use check disc for defects at boot menu). (solution: if possible, try using a different usb drive/stick).
see the following page for more details https://help.ubuntu.com/community/SquashfsErrors .
