To make this process easier, we are going to use an Windows XP image.[B] Note that this process has not been tested on Windows 7[/B]. Please also note that this process will change your partitions on the client computer. This tutorial assumes that your disk is /dev/sda1.

[LIST=1]
[]In the management portal, start a debug task for the client computer in question. Allow the client to boot and at the bash prompt type the following commands.
[]mkdir /images
[]mount -o nolock x.x.x.x:/images/dev /images (where x.x.x.x is the server ip)
[]cd /images
[]dd if=/dev/sda of=/mbr.backup count=1 bs=512
[]/usr/local/sbin/ntfsresize -f -i -P /dev/sda1
[]Look for You might resize you will need this number, so write it down. We will call this number NTFSSize.
[]Take NTFSSize and divide it by 1000
[]Now add 300000 to that number and write down as N
[]Now take NTFSSize again and multiply it by 1.1 and then round that to the nearest whole number and write it down as F
[]/usr/local/sbin/ntfsresize -f -n -s Nk /dev/sda1
[](where N is the value calculated above with a k after it.
[]If the test above ends successfully then run:
[]/usr/local/sbin/ntfsresize -f -s Nk /dev/sda1
[]fdisk /dev/sda
[]Press “d”, then Enter
[]Press “w”, then Enter
[]fdisk /dev/sda
[]Press “n”, then Enter
[]Press “p”, then Enter
[]Press “1”, then Enter
[]Press “1”, then Enter
[]Press “+FK”, then Enter (where F is the value calculated above; K must be capital)
[]Press “t”, then Enter
[]Press “7”, then Enter
[]Press “a”, then Enter
[]Press “1”, then Enter
[]Press “w”, then Enter
[]partprobe
[]/usr/local/sbin/partimage save /dev/sda1 /images/dev/[somefile] --volume=9900000000 -z1 -o -d -f3 -b
[]dd if=/mbr.backup of=/dev/sda
[]Press “w”, then Enter
[]partprobe
[]/usr/local/sbin/ntfsresize /dev/sda1 -f -b -P
[*]mv /images/dev/[somefile] /images/[somefile]
[/LIST]

Blackout,

Using these instructions for kernel 2.6.39.1 Core do not work. The ntfsresize command is in /usr/sbin, not /usr/local/. Also, on step 23, wouldn’t that just be +F without the K? We didn’t modify F be ntfssize / 1000 like we did for N.

Thanks,
Jesse

I can confirm that this doesn’t work on Windows 7 as written. Since I’m unfamiliar with the unix tools, I just destroyed my reference workstation. I managed to work with the 100Mb Win7 boot partition, but destroyed the partition containing the drive… lol
