I've used the Partitionmagic recently to make a logical partition on my laptop computer. I slept during the process under which my computer rebooted and went into a blue screen where i saw the process of resizing partition and another process going. When I woke up, I discovered that my computer kept rebooting without even logging into the windows. That is, before I could see the "Welcome" screen, it had already rebooted.

Then I saw the screen prompting me to go into safe mode....with cmd....normal boot....last best config... etc. I've selected every one of them but they didn't work out. My computer still kept rebooting. I can't log into windows.

How should I deal with this?

your system had a crash and your partition is damaged. You have no choice except to reformat your drive, erase all partitions and install xp.

You might be able to recall some data if you use your drive on another computer as a slave. Get a cheap usb to ide adapter. $20

sad....
thanks though!!
is it a cord called "usb to ide adapter"?
