I Have A Laptop And When I Start It Up I Get An Error Message That Says "We apologize for the inconvenience but Windows did not start successfully. A recent hardware or software change might have caused this." Then I Need To Choose Either, "Safe Mode" Or Safe Mode W/ Networking Or Safe Mode W/ Command Prompt OR Start Windows Normally, After I Choose One, A Couple Of Seconds Later A Blue Screen Come Up With Another Error Message And Restarts Over And Over, Can Someone Help ?

Hopefully my advice will help you...Please post back with your results as it will help others.

Thanks XpUser4Real, But I Have Tried Thoes Already And None Of Them Work, I Have No Added Hardware Or Software, When I Choose Any Of Them The Computer Just Restarts.

Did you have Autoupdate enabled?

I Dont Know What That Is. But I Dont Know If It Is/Was Enabled Or Not.

Windows Updates. IF it was enabled and computer was on and connected to the internet you could have gotten some updates. That is a change in your software.

Ok, I Think We Might Have Been Getting Updates When it Happend And YES Udates Are Enabled.

I Tried Starting The Windows Recovery Console But When I Press F-10 Or "R" To Repair I Get A Screen That Says "Set Up Did Not Find Any hard disk drives on the computer" And To Press F3 To Quit.

Watch the POST screens during the startup to see if your harddrive is identified there.
Also, enter the BIOS (setup) screens to see what your boot order is set to. Make sure you haven't left a CD in the CD drive.
The same POST screens should have a message stating what keystroke to enter the BIOS screens.
Your Harddrive may have died. That is what you will be trying to determine.

OtheHill, i dont see a post screen at all, when it restars it goes staright to the menu to choose safe mode ect.

In The Bios, The Boot Order Is #1 CD-ROM Boot, #2 Floppy Boot, #3 Internal Network Adapter Boot. Is That The Right Order ?

That is not the right boot order. I assume this is a stand alone PC? Look in the BIOS for a setting called enable fast boot and disable that. Disabling that setting will allow you to see the POST screens. I suggest you set the boot order to #1 disabled, #2 CD rom, #3 HDrive. If there is another boot option after that you can set to search for other bootable devices. Right now your harddrive isn't even is the boot order.
The date, time, drive setup should be on one of the first screens in the BIOS. Look to see what, if anything is listed for your first IDE drive. The boot order may have changed because the computer no longer sees your harddrive. If there is an option to autodetect the harddrive, try it.

Ok, Whats A Stand Alsone Pc ? And I Dont See A Setting Called "Enable Fast Boot" Also I Dont Understand How To Change The Boot Order Because When I Change It And Go Back To The "Boot Options" Screen, It's The Same.

The Only Thing That Is On The Post Screen On My Computer Is A Compaq Logo And Some Little Words That Say Press <ESC> To Change Boot Order And I Press That And The First Thing That Boots Is My "Notebook Hard Drive" So I Press Enter And It Takes Me Back To The Black Screen Where It Says "We apologize for the inconvenience but Windows did not start successfully. A recent hardware or software change might have caused this.

You may be able to get the boot screens to show by changing the settings for the Compaq logo. Like show small logo or no logo.
After changing the settings in the BIOS screens you need to hit esc to backup one screent and then SAVE and EXIT. Usually F10 and then ENTER. If you changed the boot settings you must not have saved properly.
What about the settings for the drives? Do you see anything for those?

Alright, The Boot Settings Are All Right, And I Dont See Any Settings Foir Any Drives.

Well, did you manage to get the POST screens to show? You need to do that to see if the harddrive is being recognised by the BIOS. Otherwise we are going nowhere here. If you can't find any settings for the harddrive in the BIOS screens and you can't see the POST screens there is no easy way to tell if you harddrive is OK or not.

Yea, The POST Screen Says Compaq, But Nothing About The Hard Drive.

That is the Compaq Logo. Reread my previous posts concerning changing that. When you start the computer you need to see screens that show how much RAM, drives, etc. You need to find the setting to lose the Compaq dumb Logo.

Ok well ill keep trying and if i figure it out ill post back.

The site I linked to has a Manual file there.

ok, what i ended up doing was taping f-11 on start-up and re-formating the whole computer but never figured out why that happend.

Thanks For All The Help !

restart the laptop and press del from the moment it boot down. you should be able to get to the bios this way. if you don't, then you can try clearing your cmos.
