How can you unmount a hard drive in order to resize it with partitioner (Yast2)?
I attach a screenshot.

Please exaplain how to unmount the sda2 in order for me to resize it?
Thanks

You need to boot to a LiveCD. Your OS can't unmount its root drive while running.

thanks...
how can i do this?
please advise

Download the ISO for a liveCD...pretty much any distro will do. Make the liveCD or liveUSB, shut down your computer, boot into the liveCD/USB, and use that distro's partitioning tools to modify your hard drive's partition table.

use gparted liveCD, it will help you a lot

Thank you I will do
:)

ok i did it...i burned the iso, insert the dvd with the iso image..I boot the virtual amchine with the linux machine in it and the only options for booting that it gives me are:

SUSE enterprise server 11
failsafe-SUSE enterprise 11
floppy


no dvd boot option!
Please advise and thanks

should i hold down the key "c" while booting?

select the boot media
yes, press c, and select the disk

it doesn't work
i still get the same options...no dvd option

What virtual machine? Is this not a real computer? If the linux OS that you want to resize is inside a VM, you'll need to pass the DVD drive to the VM through the VM software before the VM will see it as a boot option.

when I am in the virtual machine in linuxOS I can see the dvd disk inserted...so this means it can read it, right?
am i missing something?

how can you do this?

So this is a VM?

Please explain the setup, we have no idea what kind of system you're working with. I'm basically taking stabs in the dark based off of passing comments you're making, and you're neither confirming nor denying any of the assumptions I'm making, or answering any of our questions.

yes I have a VMplayer and I installed a virtual machine with SUSE server 11

Please let me know everything else you want to know. You are right i did not provide you with enough info

my host computer is winodws 7 laptop

In that case you'll need to look at the VMWare player documentation on booting from a CD/DVD or ISO. I found this with a quick search:

You'll need to catch it in the BIOS, before Grub loads.

i will check it!
I really appreciate your time and efforts...
THANKS!

it didn't work....

I give up!

What happened? Were you not able to enter the "bios"?

I am newbie in linux and even do not know how to mound a pen drive of hard disk in Linux. I am using Ubuntu. Please help me out and tell how can I mount as I am unable to copy data from my PC to pen drive.

i don't know if it is the del key or the esc or the F11 etc...
it doesnot work

should i press and hold whatever key is? or just press before the BIOS options appear?

you should check online (for whatever virtualization program you're using) on how to get to the boot menu (NOT boot loader!)
tell me more about it after you find out
