    Previously Installed Windows 7 Fails to Start


    Hey everyone,

    This happened to me a few weeks ago and I haven't been able to resolve it since, so I'm turning here for assistance. One fine evening, I come home and notice that my computer is giving me an error message:

    Windows failed to start. A recent hardware or software change might be the problem.

    I am then told to insert my installation CD, reboot, and follow some steps. There is one problem: I do not have an installation CD. I upgraded my erratic copy of Windows Vista to 7 (Premium 32bit I believe) last year as part of the $30 upgrade for students program, and did so online. I tried using friends' installation disks of various editions to no avail, and when I boot directly from the disks it either gives me the option to reinstall or gives me the same error message (0xc0000001, \Boot\BCD). I tried to track down my purchase information, but the email address I used to make the purchase no longer exists and my online banking service doesn't keep records past 6 months (I made the upgrade roughly a year ago). My question is, what can I do to fix this? Do I have to reinstall and lose all my data, is there a problem with the computer itself (this is not the first OS to be bucked off, it rejected Vista last May), or can I get what I need to run a system repair somehow?

    Many thanks, and happy Thanksgiving!

    Edit: Forgot to mention, the only software change I have made in the last few weeks is uninstalling Firefox and installing Chrome, and I don't think that would be the issue.

    Please fill out your system specifications through the user control panel at the top of the page.

    I assume you cannot boot this PC?

    Are your hard drives shown in the BIOS?

    You may have access to recovery of some type if you have a recovery partition or recovery disks--assuming the hard drive is still OK.

    To not secure installation media (or at least a Repair CD while you could make one) and the Product Key for a $100+ value OS which is good for life is careless. You''ll now have to Repair Win7 to have any hope of auditing the Product Key off the HD using Belarc Advisor.

    If you have a Win7 Installation DVD you said you borrowed from a friend and you are sure it is the same 32- or 64-bit version, then boot into the Repair My Computer link on second screen. Or use a 32 bit Win7 computer to make a System Repair Disk. Until then you can try F8 System Recovery Options - all options are illustrated in the blue link.

    You'll need to run Startup Repair 3 Separate Times regardless of what it reports to see if it's reparable. If not, make sure Win7 or it's 100mb System Reserved boot partition (preferred if you have it) is marked Active: Partition - Mark as Active (Method Two) then run the Repairs again.

    You can mark Active seeing a picture of your HD using free Partition Wizard bootable CD, then click on HD to highlight it, from Disk tab select Rebuild MBR, Apply, reboot. This may preclude the need to run Repairs.
    If it fails try the Repairs. If they fail, switch the Active flag to Win7 partiiton itself and try both again.

    You can copy out your files using the disk via this method: Copy & Paste - in Windows Recovery Console

    Then boot the DVD to clean reinstall Win7 and buy a new key if you can't recover the one you purchased and didn't bother to back up.
