The pc specs I have are: Amibios, Pentium dual-core,cpu E6600@3.06 GHz,CPU mem 2048mb (dual) speed 3.31GHz. I have no idea how to fix this. The pc crashed in WIN 7 after accepting updates and WIN XP crashed after upgrading to IE 9.

This pc is set up to dual boot. However, when the pc tries to boot the screen is black with white text and it has these options: WIN 7/64 bit, WIN 7/32 bit and WIN XP earlier version.
No matter which OS I choose, it just loops to windows start-up repair and the results are always windows cannot automatically repair this computer.

Safe mode is not accessible and if it starts to load at all, these errors show-KDCOM.DLL corrupt and SPTD.SYS hit enter shows. I thought I had a bootable WIN XP disk, but it is not. Therefore,I cannot try to do repairs that a way.
I never got the WIN 7/ 64 bit cd, yet it shows as drive "e". Weekly I check for updates on these utilities and then I run CCleaner, Winclean for the registry part and if necessary Road kill then Malwarebytes all in safe mode when it worked.

Here are a few other things I tried and got results from:
*Memory test= passed
*Safe Mode= never happens no matter what OS I choose
*Last known good config= never works
*loops in start-up repair cannot fix issues-no matter what OS choice is made from the black screen
*never tried to disable auto start-up from black screen because I did not understand this option well or even thought it would be a benefit. Any tips would be appreciated.

I am very intimidated by the dual boot and do not know where to begin repairs on this computer. Any tips or tricks would be greatly appreciated.

Since you have a multi-boot, the Win 7 bootloader governs, not the XP.

Not sure why you posted this in XP if you can't boot into either installed O/S, but I will move it to the Win 7 forum.

<<...and then I run CCleaner, Winclean for the registry part...>>

That may be part of your problem.

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:
  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.

    FWIW: A bootable XP CD would not hwlp...uaing such would only damage your boot files more.

  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.
<<...and WIN XP crashed after upgrading to IE 9.>>

IE 9 is not supported in XP,

Without installation disks...I don't see that you are capable of doing very much.

System manufacturer and model?

Thank you for the information and especially about the registry cleaners which I will stay away from now.
It appears my options are to take it to someone. I found my bootable win 7 usb, however, I put it in and it tells me the bootmgr is missing so-I guess I take it to someone for repairs now.

Thanks again.
