I installed windows 7 32 bit ultimate recently on a new PC. Everything worked just fine. The HD had only one partition C:, and I've installed Partition Magic in hopes I will create a new one, because I wanted to make backups of lots of documents.

It showed some error during installation and restarted. After that it doesn't want to boot anymore. I've started system recovery from DVD and I only see that there is no disk, add driver, and when I open it shows System Reserved (C:), Boot (X:). I don't know where or what to click.

I don't want to lose all the data on that system.

I messed up with PM myself, and now avoid using it. Easus, or acronis or paragon disk partition tools work. that leaves the problem that you now have, which might be corrected or exagerated by a Chkdsk, and possibly a MBR fix. –  Psycogeek Feb 23 '12 at 0:55

If you have an older version of Partition Magic, which is very likely since it stopped development in 2003 when Symantec bought it, it doesn't know anything about modern large disk partitions and doesn't run on Windows 7 or know about Win 7 paritions (unless started from a Win XP disk). It will report problems with the partition table that are not really problems, and then if you allow it, will corrupt that table as you observed. You can potentially attempt to manually edit that low level table, but it may not be easy to guess the right values. Other utilities can't recover from this type of catastropic corruption because they expect an intact partition. A drive recovery service could manually get most of the files back, at a very expensive price. Since its a new system, I would accept it as a loss, and use the Win7 install disk to repartition the drive in advance mode. (creating 2 paritions, one for win7, and one for other use). Then recycle the PM disk. Good luck.

Well said. One time I did recover a PM damaged partition table on a simple volume, by just using partition tools that did work proper for the new stuff. –  Psycogeek Feb 25 '12 at 1:15
