If I understand correctly, you had a power failure during the SP1 installation. You might have to do a repair install of Win 7. I would start from within Windows, insert the Installation disk and choose to repair your computer. This might fix whatever files were corrupted during the failed installation.

You might consider Link Removed. Burn this file to DVD then use this DVD for the repair install.

I am not sure this will solve your problem but it's worth a try. If the repair install from within Windows does not work, try it by booting to the DVD. If not, a re-install might be needed. I would use the DVD you burned with SP1 included and your original key to re-install.

I got a computer a couple of days ago that was not booting. When I started in Safe Mode, the first thing I saw was Windows SP1 reverting. So, try starting in safe mode to see what happens.

Also yesterday on a new install, it was installing 65 of 68 updates and the Electric Company decided to turn off my power. Four hours later when the power came back on, I started the system and it seemed to start normally but the three updates that had not already been downloaded, were not installed with the rest.

The update you downloaded was the Update Readiness Tool. It will normally be offered if the Update process is having a problem and you should be able to run it.

But the first thing I recommend is to step back and give the update process some time. It may be trying to repair or reinstall some component it needs. If by tomorrow or the next day, you see no progress, there are some logs we can check. SP1 is a large update and may take some time to download.
