read only drive

[moddinati]

I installed DSL on an old laptop i was given. I need to modify grub's menu.lst but the file system is read-only. I tried the 'sudo mount -o remount,rw /dev/hda1' and it gives me an error saying '/mnt/hda1 is not mounted already, or bad option'. If I type just mount it says '/dev/hda1 on /cdrom type ext2 (rw)'.

How can I get write access?

thanks

figured it out, i had to remount at /cdrom instead of /dev/hda1

file system is read-only for normal users, just try to edit /boot/grub/menu.lst file with root authority.

Thanks for the reply.

In this case the drive was mounted read-only for superusers too. I had installed DSL's frugal install which sets everything up as if it is booting off the cd. That is why hda1 was mounted at /cdrom.
