a few days ago, following a hard disk crash (win98 disk), I installed a big hard disk (10 Go) instead of 2 ones. This new disk is partitioned in 4. As I forgot to modify the /etc/fstab file, when linux boots, I can't access to my old system. So linux ask me for the root password and then, I'm root but I can' t modify any files ( eg fstab) because my system is read only. What can I do to access to my system in read/write mode ?
