I updated my Windows 7 Pro 64-bit VM this weekend. There was a big update (240 MB) but the update went through and the machine restarted properly.

From another machine, download BIOS, Chipset and Video Drivers. Put these on Ultimate Boot CD and then start your machine with UBCD.  Update the three drivers and then try to restart it.

What kind of error you have ?
Is it simply boot error or Windows is booting up and get blue screen ?
If this is only boot issue, try repair boot using installation DVD but you must do it twice.

Did it finish the updates or are you getting a "please wait" or some other message. Some of the updates in the past several months can take a really long time to finish installing.

Is it throwing any kind of errors or just rebooting itself automatically? One thing you can do is unplug any USB devices besides the keyboard and mouse to make sure it's not some kind of driver conflict or boot order error. Sometimes flash drives or external hard drives will cause a PC not to start up.

Do you use backup software to backup your system? I guess not.
Then a question, what kind of error or exception do you get when trying to boot into Windows?

I got most of files out.  I tried to   reinstall windows using the CD that came with it.  After 92%, pc will reboot back to CD.  It does not look like the windows was reinstalled.

It may be that this machine will not run Windows 10
William FulksSystems Analyst & WebmasterCommented:
If you were able to get your data off there, at this point it may be best to do a fresh install by wiping the drive first, rather than try to install on top of the old installation. No telling what has corrupted in there.

Remember,, if You have set in BIOS boot from DVD first and secure boot is not turned on, after installation and first restart computer will boot from DVD again.
Just remove DVD and restart computer again.
If Windows was installed it will boot properly from HDD

Then try to install the Windows from USB media.
it can even be bad hardware - so test ram and disk - i recommend UBCD for this:
Hardware diagnostic CD    UBCD
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
direct download :  http://www.memtest.org/
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)


**  you can make a bootable cd - or bootable usb stick
*** note *** for SSD drives  use the tool from the manufacturer, like intel 's toolbox :

for completeness -here's how i handle disk problems : http://www.experts-exchange.com/Storage/Hard_Drives/A_3000-The-bad-hard-disk-problem.html

==>>****in order to be able to  boot from CD or usb - you may have to disable secure boot in the bios

I had to leave the pc there to attend other projects, I came back to work on that this weekend. It turned out (at least it looked like that way) it was the ram. I changed the ram, everything installed fine.  very strange.....there was no err indicating ram was the problem.  thanks for everyone's input.
