Laptop : blue screen on start up

[Believil]

Hi
 I have this problem on my laptop when i try to start it up i get this blue screen telling me------

A problem has been detected and windows has been shut down to prevent damage to your computer

UNMOUNTABLE_BOOT_VOLUME              

My Laptop is a Dell Latitude D600,   If anyone knows how to fix this please help I do not know much about computers and don't want to mess around with the F2/F12 buttons on start up.
I do not have a Windows xp CD but is a genuwine Windows xp

Any Help would be appreciated.

Thanks

Have you installed any new software or hardware just prior to the occurring?

UNMOUNTABLE_BOOT_VOLUME is not a good sign.

Nope i just switched it of one day came back the next day and the blue screen came up

...don't want to mess around with the F2/F12 buttons on start up.

Is F2 = Setup?
Is F12 = Repair?
If F2 is setup (BIOS), go there and see if hard drive is recognized.  If it is, then restart and do F12.
I am hoping there is a hidden repair partition on the hard drive which sorta takes the place of the Windows CD.

yea i think it's recognised not sure what i'm looking at as i know nothing about this stuff
  I can find Internal HDD lit up in the Boot Order but that seems to be all i see of the Hard Drive

1.  i think it's recognised not sure what i'm looking at as i know nothing about this stuff
2.  I can find Internal HDD lit up in the Boot Order but that seems to be all i see of the Hard Drive

1.  You will, that's why you're here.  Trying to see if hard drive is recognized as being there.
UNMOUNTABLE_BOOT_VOLUME can mean bad hard drive or something crashed with Windows.
2.  That's good.  Hard drive is probably fully functional.  BTW, I always set boot order to CD 1st and HDD 2nd, but since you have no boot CD, it won't matter.

Move on to F12 (is that Repair?).  You may lose all your data, but what else can you do?  It's not working at all now.

[Believil]

yea it as a list as follows
 
 1  Internal HDD
 2  CD/DVD/CD-RW Drive
 3  Cardbus NIC
 4  Onboard NIC
 5  Diagnostics

[Computer_Commando]

I don't understand.  Is F12 repair?  What does the list follow from?  It must ask you something 1st before giving you the list.

[Believil]

F12 is Boot menu
F2 is set up

[Computer_Commando]

Try #5-Diagnostics.
Look for the Windows CD, you will probably need it.

when i brought it it was a refurbished laptop with a genuine copy of windows xp pro but i didn't get a CD to go with it.

dianosic's shows a list of stuff that's passed or fail

so far
--Start DST Short Test--
Test Results : Failed
Error Code : 1000-0146
MSG : Unit 0:DST Log contains previous error(s)

some other tests have passed

but now it's telling me..... No Diagnostic Utility Partition Found.  To run diagnostics, insert your dell "Drivers and Utilities" CD then select OK

I have found a Drivers & Utilities version 8.01 CD not sure if it's a dell CD thou

If you contact Dell and provide them with the Service Tag # (located on the bottom), you can get all the CD's for a small charge or maybe for free.  You can download all updates for free.  The Service Tag is the key item to know.

Start your computer by inserting the Windows startup disks or the Windows installation disk if your computer can start from the CD drive. Or go into your recevery console.
When the Welcome to Setup screen appears, press R to select the repair option.
If you have a dual-boot or multiple-boot computer, select the Windows installation that you want to access from the Recovery Console.
Type the administrator password when you are prompted to do this.

Note If no administrator password exists, press ENTER.
At the command prompt, on the drive where Windows is installed, type chkdsk /r, and then press ENTER.
At the command prompt, type exit, and then press ENTER to restart your computer.
After you repair the volume, check your hardware to isolate the cause of the file system damage.
