Upgrade to Lion messed up my Windows NTFS partition - How can I recover it?

Last night I upgraded from Snow Leopard to Lion (downloaded from the app store). I had a boot camp partition with windows 7. That partition was NTFS. After the successful upgrade, i can't boot into windows. Disk utility shows the partion as Disk1s4 and it says it's MS-DOS (FAT) and not NTFS as it really was.

I tryed booting with a windows DVD but it says that the partiton is RAW.

That Windows instalation has all my work data. is it there a way to recover it? Why would Lion touch it?

Please, help me!!

Regards,

Julián

Same thing happend to me.. I spoke to the apple care folks on the phone... they seem to not know either whats going on.... Hopefully someone over there knows a solution. They told me to wait a few days for the tech to get back to me.

Very strange.

Don't wait... the Windowspartition is useless. What happened is that the upgrade process creates a newpartition of 650mb for that new recovery feature... the space for thatpartition comes from first 650mb of the windows partition. Big apple mistake...that partition is not controlled by the MacOS. If space should be taken, it shouldcome from the MacOS partition. Horrible and malicious bug. That kills the MFTof NTFS. And that's not all... it also changes its type to FAT.

What I did is the following:using paragon’s partition master, I changed the partition type to NTFS (x07).

then, I tried to regenerate theMFT and boot sector with TestDisk. It didn't work.

I took the HDD out, put it on aPC and used GetDataBack NTFS to try to get some files from the mess that theLion's setup did. I manage to get some (not all!!) of my work (docx and xlsx).I lost lots of pictures, videos and mp3.

I'm really annoyed with appleand what the upgrade did!
