i have the same problem i only just 4 hours ago just got my laptop back from repairs. and this shit happens i hate m.s.

boot from the Windows 7 DVD or Windows Recovery Environment (F8)[1] and run the command prompt and run this: DISM /image:C:\ /cleanup-image /revertpendingactions (replace C: with the drive where you installed Windows 7) if you got Error messages, boot from the Windows 7 DVD, select setup and press Shift+F10 to enter the command prompt. Run the DISM command from there. This reverts all pending operations. Now you should go back to Windows 7 RTM. if this doesn't work, boot from the Windows Recovery Environment again, start the command prompt go to C:\Windows\WinSxS and run ren pending.xml pending.xml.old to rename the XML. Try to boot Windows now. if this doesn't work, select the last good known configuration. When you're back at Win7 RTM, please run the Windows Explorer and go to the folder "C:\Windows\Logs\CBS\" and copy all files to your document folder, also copy the setupapi.dev.log from the folder C:\Windows\Inf and the file "C:\Windows\winsxs\poqexec.log " to your document folder (otherwise you can't upload it), zip all files into 1 ZIP and upload the zip to your SkyDrive [1] and post a link here.
