    I get when I try to start my computer. I have had problems with my power supply losing connection and the battery has run down a few times. I have read things about using the Windows XP disk but I cannot figure out how to start windows using this. I only have the upgrade disk because this computer originally had '98 on it. Please help, I am getting a new computer for X-Mas and don't want to have to buy a new one right now. Thanks.

    Also, do you have a Windows XP disc available? If so, procede below...

    1. Make sure the computer is set to BOOT from the CD-ROM or DVD-ROM drive.

    2. Insert the Windows XP CD-ROM into your CD-ROM or DVD-ROM drive, and then restart your computer.

    3. When you receive the "Press any key to boot from CD" message, press a key to start your computer from the Windows XP CD-ROM.

    4. When you receive the "Welcome to Setup" message, press R to start the Recovery Console.

    5. If you have a dual-boot or multiple-boot computer, select the installation that you have to use from the Recovery Console.

    6. When you are prompted, type the administrator password, and then press ENTER.
    Note: If you do not have one, just press ENTER.

    7. At the command prompt, type chkdsk /r and then press ENTER.

    8.Once it has cmopleted, type exit, and then press ENTER to quit Recovery Console.

    Let me know if you have ANY problems with these instructions.

    The blue screen pops up every time right after the windows XP screen comes up. I do not have the original XP disk. I only have the upgrade cd. I tried to boot off of this unsuccessfully. Can someone let me know if I can use someone elses XP disk to fix the problem. Thanks for your help.

    Bjgarrick most likely has the solution, unless you have hardware failure.

    So..Im a little confused that you said you dont have the original XP CD, but you do have the upgrade CD.

    Upgrade CDs are XP CDs too, and even full versions. Only the setup method has been modified.

    That CD will work for this method.

    Ok, I did not realize that. I tried to boot my computer off of the XP upgrade cd but it did not seem to work. It just kept doing the same thing. It didn't seem to be booting off of the cd at all. Maybe I am doing something wrong but I hit f1 when the computer turned on and changed the boot order to run off of cd first. The windows screen came on and then the blue screen just as before. I just figured you couldn't use the upgrade cd. Guess I was wrong. Thanks for your help.

    Can you tell me what the front of the XP CD says?

    its supposed to be botoable.

    Try changing your BIOS to ONLY boot from CD, disable the rest. This should force the boot process.

    Will your computer boot into safe mode (one of the choices at the unmountable boot volume screen)? If so, and without the XP cd in your drive, try the following. I had an UMBV error last month and this worked perfectly for me.

    Boot into safe mode.

    Double click My Computer.

    Right click on C drive and select Properties.

    Under the Tools tab, click on check now in the error-checking section.

    I clicked both of the boxes to check for errors. It will do this on next restart.

    Restart computer.

    If yours works as mine did, it will go through the whole chkdsk process (45 minutes for me). At the end, my computer booted normally and has ever since.

    If safe mode won't work for you, or your harddrive is a goner, this won't help.

    If you have a "slow" monitor, you may not be seeing the text that says "Press any key to boot from CD....". This text will come on the screen for only about 7 or 10 seconds before the PC moves on to the next boot device listed in the BIOS. I've seen monitors that are slow in warming up, or slow to react to screen changes to the point where you wouldn't see the prompt. Also, if your monitor's VHold or VPos is off, you wouldn't see the prompt. So, when powering up the PC, keep your eye on the CD drive, when it starts to spin up it's looking at the CD; at this point press the space bar a few times. Wait about a second or two between each press of the space bar. You should eventually see the blue setup screens with a white 'status' bar at the bottom that displays file names and will occasionally prompt you for certain actions. After a bit, you should get to the part that bjgarrick described above. GOOD LUCK!!


    BTW- your upgrade CD should boot just like any other XP CD....

    Just a small thought.

    This is an old machine. Has the Cmos battery nearly run out?

    Sorry I just cannot get anything different to happen. I hear my cd rom drive spinning but it still just goes to the xp screen and then to the blue unmountable_boot_volume screen. For whoever asked before, my disk is just says Microsoft Windows XP Home Edition. It also give setup instructions: Click Start etc. Version 20002. Any other setting that could be making it difficult to boot from the cd?

    Yes, it is an old machine. Don't know much about the cmos battery.

    When I try to force the cd to boot by disabling the other devices all I get is a black screen that says "Operating System Not Found". Is there a possiblity my disc is not able to be booted off of. Would it be possible to use someone elses disc or can I only use the one that loaded my operating system?

    Is this pirated?

    Im getting a lot of double talk, my OS CD vs my upgrade CD. The upgrade CD is XP, and the other CD is...what?

    Yes another XP CD can be used to follow the instructions listed here.
  17. cwtcc55

    cwtcc55 Private E-2

    Sorry if I'm being confusing. I originally had windows 98, upgraded to XP. The only disc I'm talking about is my XP upgrade cd. I guess I'll try someone elses, mine doesn't seem to be working. thanks again for your help.

    Oh, I see now.

    Well, there is a possibility that the cd drive is old enough, and the bios is old enough, that it will not boot to the CD.

    Let us know how the other copy fares.

    Please explain exactly what happened here. Is this a manufacturer's option or did F1 take you to setup (the BIOS)?

    If you entered the BIOS after you set the boot to CD, did you save the changes before exit? This is easy to forget and then the changes don't 'take'

    Did you ever see the message 'press any key to boot from CD'?

    Please state the model / make of pc. I believe I saw laptop?

    Since you were offered a boot from CD option it is reasonable to assume one exists. Therefore id you can borrow a friend's XP Cd to do the Check Disk procedure, please do so as this is the most likely cure for your ills.

    Do you have any windows 98 disks, CD or floppy if it becomes necesaary to control the pc from floppy?

    Finally is there any possibility of temporarily moving the hard drive to the pc you are using for the internet to do the check disk?

    I don't have my original windows 98 disc. My fiance's computer is what I am using now and it is a MAC, so the chances are not good that I will be able to remove the hard drive. I also don't think I am qualified to do that since I wouldn't know where to begin. i am going to borrow a friend's disc and try it when he gets home later. Thanks again.
