The Windows 7 update "System Update Readiness Tool for Windows 7 (KB947821) [May 2014]" will appear hung or stuck during the update process. It will get to about 80 to 90% and just the hard drive activity is all that will indicate that it is still working on the update process. Many have noted it to take several hours. In our own install of this for a client it took almost 6 hours to complete on a system that failed the SFC scan test.
If you are installing the System Update Readiness Tool for Windows 7 (KB947821) besure to allow for a long period of time to install. Do not stop this install or you may corrupt the system to a point where it will not boot and you will be required to reload Windows from scratch.
Recovering various HP and even some Dell system after a hard drive failure without the recovery DVD's can be frustrating. If the owner forgot to create the DVD's, there is a chance that you can still burn them later once the computer is running again. If the owner created the DVD's and lost them, you might be forced to contact the vendor and purchase a new set.
Well, if the recovery partition is still accessible on the original drive, here is a how to recover from the HP recovery partition that might help get the system recovered to the factory default installation.
A client attempted to install an upgrade to Kaspersky Anti-virus, but the install was interrupted and so the system was left in an unstable state. Continued use of the computer frequently resulted in the following Blue Screen of Death.
One of the side effects from this issue was that the hard drive was constantly getting corrupted and several drivers would fail to load. In order to get the system to boot we had to go into safe mode, run a check disk on reboot, and then the system would finally boot and run for a short period of time, which was all we needed.
Client's HP Pavilion M9400t was reported as having a noisy fan and then would not boot any longer. The power supply was the primary reason for the system not powering but after replacing the power supply the system would continually reboot. Using the F8 key while booting we were able to force the system to stop on the error and not reboot. This allowed the error message STOP 0x0000007B to be displayed. This error most often is reported when there is a hardware issue.
After backing up the hard drive using Norton Ghost, we went through a series of tests by removing hardware. In this case the video card was an add-in so it was removed but the problem still persisted. Next we checked the BIOS settings and noted the default for the SATA drive was set to RAID. We changed this to IDE and rebooted the system. The system booted normally.
When using the recovery CD for various eMachines (T2080, T2792, T3065) with Windows XP, the computer hangs or freezes at the Name My Computer stage of the process. After spending some time researching the issue, other technicians have noted that the system is stuck trying to configure the video.
The easiest way around this is to shutdown and reboot in VGA mode as follows. If your not sure how to shutdown the computer at this point, just press and hold the power button for about 10 seconds until the computer powers off.
