Get access of windows partitions in linux

As root, edit the file /etc/fstab e.g. let your windows C drive partition is /dev/hda1 and it is 'fat 32' file system. So to mount the C partition in /windows/C directory, in the /etc/fstab file, make an entry as
/dev/hda1 /windows/C vfat umask=0000 0 0
Note that umask=0000 will give write permissions to every user. To give write permission only to root, replace by
umask=0002

Create ISO image in Linux

To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it.

$ dd if=/dev/dvd of=dvd.iso # for dvd
$ dd if=/dev/cdrom of=cd.iso # for cdrom
$ dd if=/dev/scd0 of=cd.iso # if cdrom is scsi

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command.

$ mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.
