Windows 7 - Can not find partition

I have windows 7 rc x64 installed , which occurs
Partition Magic installed some errors occurred when
i know it was another error and reset machine,
the operating system does not boot more, when getting in
way of security to try to load the file
classpnp.sys reset it, is that Windows does not
"see" more that the partition where it is installed.
How do I see windows again
partition is ?!?!?

obs.: The error occurs in Classpnp.sys he changed the boot
for a partition where you have some files in
recovery ... recovery of the OS did not work and
bcdedit, the fix also does not have can'tI
access the partition ...

Format/Reload OS

Partitioning Software is bad for a majority of reasons, but has it's limited uses for extreme situations.

Only other option to recover data,,,, take the drive and hook to another system and see if you can access it. If not, the data is probably dead. or try a program called TestDisk to try and recover data from the corrupted partition.

But if you don't know what you are doing,,, you could make things worse. Take it to a professional.
and Geek Squad are not professionals.

I can access the partition, and
see / read / edit / copy the data using other Systems
Operational. There is no way that I can
do return to see the Windows partition? My problem
does not see more windows partition, I can not
no more install it there.

You will prabably need to reinstall windows,,,, see A "Stop C2" Error Is Caused by the Classpnp.sys Driver

Try marking the partition as active using diskpart.
Does it show in disk management?

Why people use Partition magic is beyond me, I've used it once, got the 'bootmgr is missing' bullsh1t, and had to reinstall the OS!
W7 has an adequate partitioning tool. I certainly wouldn't recommend using a potentially damaging software like partitioning tools with a RC OS anyways.

I have not tested the partition manager in 7 yet.
In vista you can only resize down to half the free space.
Other partition managers will do all if wanted.
Has this been changed in 7?

Hi, Partition Magic is not compatible with the new NT6 partitioning rules. I understand there are no plans to update it. There are other partitioning apps. that work successfully and can be useful when Windows Disk Management functions are too limited. To recover from the situation, you could try this : Shrink the partition a little using a bootable partition manager e.g. Gparted - leaving a small amount of unallocated space. Boot the 7 dvd, start to install , select Drive Options ( advanced ). Extend the partition to it's full size again , then abort the install. You may need to run startup repair from the 7 dvd.

What you said about Vista is wrong. It's a common misconception that you're only able to shrink it by half. Vista & 7 only limit you because of the position of the MFT files on the disk. See here for a workaround, it works in 7 too;

BTW Tepid, good shout wih Testdisk, it's a very good tool that pulled me out the sh1t when my external hdd decided to die

Um, i do not believe this is correct, you can still only shrink half the free space in windows shrink, that's it.....
there are better tools. The method in that post may get you a few more gig's or meg's, but you will still only be able to shrink half the free space. That post does not claim to be able to shrink more than Half the free space, only that you might get more space to shrink cause you are creating more free space by cleaning up the system.

I agree a defrag run a couple of times first is advised, but, you don't want to shrink more than your existing OS needs (meaning, deleting the pagefile, hiberfile, junk temp files and all are good maintenance practice, but, if you dump all those files then take the space that some of those files need, you may end up with a broken initial OS), you will be robbing it of needed space,,, so the scenario in that post may work, but it may not be the best idea.

I use something like Gparted or Partition Magic 8 booted from CD (or USB), not run from within windows environment to resize partitions as needed.

LOL, you clearly don't understand what has been written. Read the post again!!

It is possible to shrink more than half, you will not be robbing space that the OS needs, if the OS needed it, it wouldn't let you take it!
MFT is the only holding you back, NOT free space. With the method i posted (albeit a long-winded one ) it tells you how to move the MFT.
When i used that method i freed up more than 80GB, hardly the MB's you're claiming it will do.

Also, common sense is a wonderful thing, it's a shame most of us don't possess it. All the files you claim may break the OS hardly take up any room at all (well, not with 2TB HDD on the market now). You are right in claiming that if you DID take up space that the OS needed you would break it. This, however, is highly unlikely.

Good luck with your Gparted, Partition Magic 8 and bootmgr is missing LOL

P.S Look on the howtogeek website for a similar post on moving the MFT for partitioning. I may not be credible but they are. They know what they're talking about.
