Windows Vista won't start

I try to boot my computer and I basically get a message that says that there
is no operating system. My computer was fine the last time I used it and shut
it down. I had recently upgraded from Windows XP to Windows Vista. I really
have no clue as to how this could have happened.
 
Do you get a screen listing 2 operating systems?
Like
1. Previous Windows Version
2. Windows Vista
 
You don't provide much information. Depending on the message, you could
have left a floppy disk in the computer. You might try to use your Vista
install DVD and see if the os is recognised when you do a startup repair.
 
The first thing that comes up is normal – the big red Compaq logo.
Then the screen changes and “Missing Operating System†shows up.
Nothing else is listed.
 
when I had this problem it was the cable that connected the hard drive to the
motherboard. I replaced the cable and it fixed the problem.

I tried using my Vista CD and followed the steps under "startup repair" even
though there still was no operating system in the box- this appears to work.
Then the computer reboots and my desktop appears. I wait a minute to make
sure the system has fully loaded as Vista has had to do before this problem.
I click on some Icons such as Microsoft word and Internet Explorer- neither
will appear now, so I try the process over again through the start menu they
both appear Word works fine but Explorer refuses to load the bar on the
bottom that shows the progress in loading isn't going beyond 1/3 full. When
it finally does after about 10 minutes the mouse isn't able to click on
anything other than the start menu.
 
I don't think my problem could be related to a connection to the motherboard
since the computer itself is only about 8mo. old. This problem is so
frustrating... I don't know what to do next...
 
If you can get into event viewer, have a look for errors
under System and Applications, if you find one, and you will, double click
on it and follow the link, there will be information about what caused your
problem.

Event Viewer is found at
Start/Control Panel/Administrative tools/Event Viewer

Thank you all for your great help in getting my computer usable again! It
seems that using the Vista CD did the trick- thanks Dave. My computer still
takes a minute to upload desktop items but it's not as bad as it was an hour
ago!
 
Hi LB--

What I'd do now that Startup Repair seemed to fix things is to run SFC, and
check services.msc in your run box and turn off unnecessary services, and
also use Task Manager to check that you aren't running processes you don't
need to run. Also type msconfig into your run box and see what you're
loading at startup.

When you get the error "OS not found" or "Missing OS" or "Setup didn't find
any hard drives" it's usually caused by:

• The basic input/output system (BIOS) does not detect the hard disk.
• The hard disk is damaged.
• Sector 0 of the physical hard disk drive has an incorrect or malformed
Master Boot Record (MBR).
Some third-party programs or disk corruption can damage an MBR.

***SFC as a Remedy***:

SFC or System File Checker is a bit like the spare tire in your car or a
backup battery I suppose. In Vista of course, they have changed it somewhat
and come up with a new name--Redmond stands for name it something different
twice a year and now it's part of WRP or Windows Resource Protection. It
scans protected resources including thousands of files, libraries, critical
folders, and essential registry keys, and it replaces those that are
corrupted with intact ones. It fixes a lot of problems in Windows XP, OE,
Windows Vista, Win Mail, IE6, and on Vista or if it is installed on XP, IE7.
It protects these things from changes by any source including
administrators, by keeping a spare of most of them.


How to Run SFC:

Type "cmd" into the Search box above the Start Button>and when cmd comes up
at the top of the Start menu>right click cmd and click "run as Admin" and
when the cmd prompt comes up at the cmd prompt type "sfc /scannow" no quotes
and let it run. This may fix things quite a bit. It replaces corrupt files
with intact ones, if you're not familiar with it.

Good luck,

CH

If it takes that long to get the desktop to load, there is still a problem
somewhere. It doesn't take much and I would suspect a registry error. Can
you go back and do a System Restore to where it was running well? If System
Restore isn't working it may take a reinstall to get it back to where it
should be.
