I cloned my Dell XPS laptop’s 500GB hard drive to a 240GB SSD. The clone took over 5 hours to complete successfully. After rebooting, I received the following:
Windows failed to start. A Recent hardware or software change might be the cause. To fix the problem:
1. Insert your windows installation disc and restart your computer.
2. Choose your langugae settings, and then click next
3. Click "repair your computer."
Info: The boot selection failed because a required device is inaccessible.
After trying many different things from many different blogs, the following steps fixed my problem:
Boot off of a Windows 7 disk and go to Repair. Open a command prompt (skip or cancel and errors you get about recovery).
At the command prompt, set your correct Windows 7 partition active (thanks to gregrocker (http://www.sevenforums.com/members/gregrocker.html) on this post: http://www.sevenforums.com/installation-setup/46234-active-partition-boot-problem.html):
SELECT DISK # (for Windows 7 disk)
select partition # (for Windows 7 partition)
After setting this, I restarted my laptop and then received a slightly different 0xc000000f error.
I then restarted my computer and booted off the Windows 7 disk again and chose repair. Windows automatically repaired my disk successfully and my laptop rebooted properly.
Thanks gregrocker! You are awesome!
