1)do:
ls -l /
and examine the output. Does vmlinuz exist? If so what is it? Is it a file or is it a symbolic link? If it is a link, where does it point?
2)Boot block is also known as the MBR (master boot record) and is first 512 bytes of /dev/hda and contains the partition table.
3)In most cases, a CDROM disc must be mounted before reading. So first place the CD in the drive. Next find out where the drive gets mounted. It may be mounted on /cdrom or /mnt/cdrom or /media/cdrom. Check /etc/fstab for mount information:
cat /etc/fstab
You might see output like:
james@dualcrush:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

It is this line
/dev/hdc /media/cdrom iso9660 ro,user,noauto 0 0
that tells the system how to mount a CDROM disc. To mount it (you may need to be root user):
mount /media/cdromThen read it:
ls /media/cdrom
