Can you mount your Linux partitions when you're using your boot disk?

ok,i don have the boot disk,if i can mount the partition,what should i do and if i can't mount the partition,what the other way i can do?thanks

You can try twho methods of mounting, as ext3 and as ext2. If no success, there's a big problem...
First try to mount them. I hope everything will be OK.

it sounds like the linux installation is corrupted. did it work before, or is this a problem coming from no where? you might need to reinstall the kernel or ever the whole system.

Thanks mara for ur reply,but im too new in linux,how to mount the ext3 ,im using the ext3 now.Is it using the boot disk or i can boot from linux 7.2 cd ,if so what command should i use to mount,can u give me step by step guidance.Thanks a lot.

Let's say you're going to mount /dev/hda5 (to see all your partitions run
fdisk /dev/hda
and then press 'p' tolista partitions, use 'q' to quit).

mkdir /mnt/hd_5
mount -t ext3 /dev/hda5 /mnt/hd_5
(as ext3, as ext2 it's similar:
mount -t ext2 /dev/hda5 /mnt/hd_5
)

Mkdir is used to create a directory your drive will be mounted to, mount is used to mount.
If you have more then one partitions, you'll need to mount also /dev/hda6 etc.

hi mara,me again,sorry for disturd u ,i know my problem already,i can't mount my root file system,is it?i boot from cd 7.2 linux rescue and follow the command mount -t ext3 /dev/hdc5 /mnt/hdc5 but it return me invalid argument,then i mount hdc6,7,8,9 is ok.As u know i using dual boot.Any idea again?I very need ur help,i don want to format it.

Your /dev/hda5 may be just a Windows partition. Don't worry but mount parttions 6,7,8,9 and look which one is your /

cheng · 08-26-2002, 09:37 AM

yes,i know,dev/hda5 is my window partition and hdb is my cd rom drive.i mount dev/hdc5 but cannot,it return me invalid argument but for dev/hdc6,7,8,9 is ok,so how to define which one is my /.Im using cd to boot,then i boot from linux rescue,is it correct?Thanks

If you don't have separate /boot, there's only one partition where you have it. So just mount them all, enter the directories and find the one with /boot. That's your root partition.
