i have a partition for windows and another for linux
windows : hda1
i want to change hda1 into a ext2 filesystem.
can anyone give me a step by step guidance on how to use sfdisk?
i searched on the net and found this site http://www.die.net/doc/linux/man/man8/sfdisk.8.html
and follow its instruction to save in case i do something stupid
so i did this
sfdisk /dev/hdd -O hdd-partition-sectors.save
and got this msg
Checking that no-one is using this disk right now ...
BLKRRPART: Invalid argument
This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
Use the --force flag to overrule all checks.
so i am not very confident about carrying out this partition for i do not want to delete my other partition wrongly. someone pls help me.thks in advance!
