Yesterday I thought I should make a new Partition on my hard drive as a backup

I used Gparted Live CD
My hard drive only had 1 partition before, which had Windows Vitsa home preium installed
Now i did the following actions Shrink primary partition by 40gb or so and then used the empty space to create a new partition using the NTFS.

The Problem is that A power cut happened while it was still doing it. After the power cut i booted in Gparted and there was an empty space where i wanted it and about the right size. Gparted called the primary partition unknown format. Then i booted from Vista CD and tryed to repair my operating system. their was no operating system to select so I then clicked load drivers and looked for C:. Double clicked it and it said can't read C: or something, format now. i tryed to format but windows couldn't.

What should I do next?
More importantly can i get my Data back?

It sounds like the drives boot sector has been deleted and because of a power cut a new one was not written to the disk.

To recover it use Testdisk (http://www.cgsecurity.org/), and follow these instructions (http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step)

Looks Good
Will try when no risk of a power cut

While doing backups s good - doing it on the same hard drive by partitioning it not such a good idea.
As you have actually proven by the problem with the power cut & possible data lost. ( A UPS would have saved you).

I have had several customers do the same thing as you - and it proved completely hopeless-- when the hard drive fails-- wheres the backups ?? ON the SAME drive thats failed, and usually they cant be recovered.

Another 2 examples: you have a power surge through the PC, even if you have a seperate drive in that PC as backups - it fries as well.Someone steals your PC-- Wheres the backups. GONE as well.

When doing backups you want to have them in a separate location (another PC) or media, either external drive or CD/DVD.

Edited: as for getting the data back - depending on if testdisk works or not, there are other options. Some free some not.

Okay then i'll use this partition to look at windows 7 Beta then, instead of a backup

The beta is ready to die (about the 1st of Aug). You'll have to get the RC

It may say its Ok but if its not booting then its Not.

in the original Post, you said you booted from the Vista dvd, is this how you tried to do a start up Repair- Illustrated guide (http://www.bleepingcomputer.com/tutorials/tutorial148.html).

If the system is badly damaged, you may be able to boot the PC from a Linux live CD, and try to recover your data to an external drive.

If not, you may need to slave the drive to a working PC then use a recovery program to try and recover your data.

If you need a GOOD data recovery program, I suggest GetData Back (http://www.runtime.org/) -- there are others, but I have found this will recover data that many other programs dont. There is also Easeus data recovery (http://www.easeus.com/). BUT get data back works a LOT better than Easeus.

The programs are not free, but the free versions allow you to see if the data is recoverable. If you are having to buy one, then get "get data back" ( its better)

In fact I have just recovered today a Customers drive using get data back, 78GB worth of data that Easeus missed most, and many others simply couldn't do it.

OK took 18 odd hours to scan the drive but it did the trick. The drive had failed big time.

Yes I just did but I tryed to copy the backup boot sector over the Boot sector, by I got Can not ovewrite NTFS boot sector
Should I rebuild the Bootsector

Okay here's the lastest
I can't boot into windows.
When i put the hard drive into another computer i can see all the normal things.
Startup repair says my computer is fixed, but its not.

Anyone got any ideas to boot into windows?
