View Full Version : [ubuntu] cannot boot from cd/usb

April 25th, 2011, 11:26 PM
](*,) Hi all,

Actually Ubuntu 10.10 installed on my laptop Toshiba A10-SP100. I was testing some ligh distros, lubuntu, elive, ubuntu ue, Mint lxe, and others: suddenly I am obtaining the following errors:

1.Cannot be mounted Ubuntu 10.10 i386
Error mounting: mount exited with exit code 1: helper failed with:
mount: block device /dev/sr0 is write protected, mounting read-only
mount: wrong fs type, bad options, bad superblock on /dev/sr0, missing codepage or helper program, or other error. in some cases useful info is found in syslog-try demesg, tail or so.

2. The disc controler for udf, iso 9660 is not ready or present.

An error occours when mountig /media/cdrom0
Press S to omit or M to recover manually

I found various recomendations to mount it, editing fstab etc. but nothing worked. Also the fstab appears be incomplete.

Any solution? Do not have the USB boot option.

Thank in advance for the help.:D
