Windows 7 Ultimate reboot cycle fix

I recently built a new computer and installed Windows 7 Ultimate. Everything went smoothly during the install until it came time for the final reboot and the computer would display the bios and then begin and endless reset loop. This was a difficult issue to track down. I thought it could be hardware and started removing parts, putting RAM in different slots, and googling a lot.

There were many posts about this issue during upgrading from Vista, but I was doing a new install. I thought maybe the disc was corrupted in some way too. After several reinstalls and a few hours of sleep I noticed that the windows 7 was installing on D drive and not C: even though I was using the whole SSD as one partition.

 I found this article How to Manually Repair Windows 7 Boot Loader Problems and it fixed my problem.

The first thing you’ll need to do is boot off the install disc, and then click through until you see the “Repair your computer” link in the lower left-hand corner.
You’ll need to choose the correct installation of Windows and then click the Next button.
And then you’ll get to the System Recovery Options screen, where you can get to the Command Prompt.
If you want to restore the master boot record, you can simply type in the following command:
bootrec /fixmbr
You can also write a new boot sector onto the system partition with this command (which is often more useful):
bootrec /fixboot
And of course, if you just use bootrec /? you’ll be able to see all the options.
