I am tring to format my hard drive but when I try to load windows but it will not go to my dvd rom when I turn it on it says invalid disk

Hi


Which way have you tried to do the erecovery method
please add comment below explaining which way you did it


many thanks

To check your hard disk drive if its detected, turn on your computer and press DEL or F2 to enter BIOS setup. Then go to standard cmos setup and there should be the hard drive detected as Primary or Secondary IDE or SATA. If detected and not loading into windows that case your operating system is corrupted. However If your hard drive is not detected on your bios, turn off your computer and unplug and plug your hard disk drive then turn on your computer start pressing again DEL or F2 then check again your hard drive if it is detected.

If your hard disk drive and cd/dvd rom drive are the same cable you can switch the cable to check if the cable of the hard drive are ok. After you have checked and you found out that the two cables are ok that means you will have to format your computer. But you must backup all your data and files before doing so. Formatting your computer will erase or delete the entire space of the partition which you perform formatting.

Here is the video tutorial on how to format your computer using windows xp

Have a nice day.

If you dont know how...this is the last thing you should be doing
assuming that you realize formatting you had disk will result in a laptop without an OS (ie windows) just an error saying "invalid system disk"
go to dos by typing CMD into the run command
type
diskpart [enter] select disk 0 [enter] select partition 1 [enter] format [enter]

You must partition the new hard drive, sometimes that step can be bypassed by just hitting Enter at the prompts. It has to be partitioned and then the partition has to be formatted through the Windows setup routine. By sure and partition it as a primary partition.

When you install Microsoft Windows XP, you may receive the following error message:
[Files Needed]
The file 'Asms' on Windows XP Professional CD-ROM is needed. Type the path where the file is located, and then click OK.
This issue may occur if the Setup program cannot communicate with the CD-ROM drive.
To resolve this issue, use the appropriate method for your computer.
Hard disk formatted with FAT or FAT32 file system
If the hard disk is formatted with the FAT file system or with the FAT32 file system, follow these steps:
Use a Microsoft Windows 98 Second Edition or Microsoft Windows Millennium Edition (Me) Startup disk with CD-ROM drivers to restart the computer.
Copy the Xcopy.exe tool from the Windows 98 Second Edition CD-ROM, the Windows Millennium Edition (Me) CD-ROM, or the hard disk to the Windows Startup disk. To do this, use the appropriate method.
Windows 98 Second Edition CD-ROM
Insert the Windows 98 Second Edition CD-ROM in the CD-ROM or DVD-ROM drive, and then at the command prompt type the following lines, pressing ENTER after you type each line, where cd-rom is the drive letter of the CD-ROM or DVD-ROM drive:
c:
copy cd-rom:\win98\smartdrv.exe
copy cd-rom:\tools\oldmsdos\xcopy*.*
Windows Millennium Edition (Me) CD-ROM
Insert the Windows Millennium Edition (Me) CD-ROM in the CD-ROM or DVD-ROM drive, at the command prompt type the following lines where cd-rom is the drive letter of the CD-ROM or DVD-ROM drive, and then press ENTER after you type each line:
c:
copy cd-rom:\win9x\smartdrv.exe
extract cd-rom:\win9x\win_17.cab xcopy.exe /L c:\ xcopy.exe
extract cd-rom:\win9x\win_17.cab xcopy32.exe /L c:\ xcopy32.exe
extract cd-rom:\win9x\win_19.cab xcopy32.mod /L c:\ xcopy32.mod
Hard disk
At the command prompt, type the following lines where drive is the drive letter of the hard disk where Windows is installed, and then press ENTER after you type each line:
c:
copy drive:\windows\smartdrv.*
copy drive:\windows\xcopy*.*
Eject the Windows 98 or Windows Millennium Edition (Me) CD-ROM, and then insert the Windows XP Professional CD-ROM.
Copy the I386 folder and all its subfolders to the hard disk. To do this, type the following lines at the command prompt where cd-rom is the drive letter of the CD-ROM drive, and drive is the drive letter of the hard disk, and then press ENTER after you type each line:
smartdrv
xcopy cd-rom:\i386 drive:\i386 /e
Restart the computer, and then start the Setup program again.
When you receive the error message, click Browse, and then type the path of the I386 folder on the hard disk.
Note You may be prompted several times for the location of this folder. If Browse is not available, see the "Hard disk formatted with NTFS file system" section.
Hard disk formatted with NTFS file system
If the hard disk is formatted with the NTFS file system and you are upgrading an earlier version of Windows, use one of the following methods.
Method 1
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 (http://support.microsoft.com/kb/322756/ ) How to back up and restore the registry in Windows
When you receive the error message, press SHIFT+F10 to start a command session.
Type regedit.exe, and then press ENTER.
Click HKEY_LOCAL_MACHINE.
On the File menu, click Load Hive, and then load %Windir%\System32\Config\System.sav.
When you are prompted to specify a name, type Test.
Locate and then click the following key:
HKEY_LOCAL_MACHINE\Test\ControlSet1\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
Delete the UPPERFILTERS and LOWERFILTERS registry keys.
Repeat steps 6 and 7 for the other ControlSet# keys under the Test hive.
Click File, and then click Exit to quit Registry Editor.
If the path in the error message is the correct drive letter for the CD-ROM drive, click OK to continue the Setup program.
If you receive the error message again, the Setup program cannot correctly read from the CD-ROM drive, or the path information is incorrect. In this case, restart your computer and let the Setup program resume.
Method 2
If you cannot start Regedit.exe at the command prompt, and there is another available partition where you can install Windows on the hard disk, follow these steps:
Install Windows in the other partition.
Start the new installation of Windows, and then start Regedit.exe.
Follow the steps in method 1, but load the System.sav hive from the original Windows folder.
Method 3
If you are not using a retail Windows XP CD-ROM with a hologram (for example, if you are using a burned CD-ROM), try to run the Setup program from a retail CD-ROM with a hologram. To verify this, start the computer by using Recovery Console, and then check the C:\$win_nt$.~ls folder. Look for the Asms folder. If the folder is missing or the files that it contains are zero bytes, the CD-ROM was not burned correctly.
For additional information about how to use Recovery Console, click the following article number to view the article in the Microsoft Knowledge Base:

Are you installing from the SONY-supplied "System Restore" CD/DVD disks, or from a "generic" Vista DVD-ROM?

The SONY disks _should_ have the correct drivers for your notebook computer.

you reformat your hard disk and install guienuine microsoft window xp your problem will be fix

 Because you have a packard bell, I would assume this is a much older system.  You would have to put Windows 98 on it I presume unless you have enough memory to do XP.  Either way you will need one of the Windows CDs to load the software... I ve seen Win98 on Ebay for $50. Once you have the software, you will need a boot disk.. You can download this off the Internet.  What this boot disk does, is it loads the utilities that you need like to format the hard drive and it will also load the cd rom drivers so you can use your cd rom and install windows from the cd... Load the boot disk and once its loaded you can use the format command.  At the C Prompt, type     format C:     It will erase the Hard Drive. Once completed,  Reboot the computer with the boot disk still in. When it gets done you can install Windows. Most times it will assign the cd rom drive a letter. Usually D or E.   When it comes up type    E:\Setup This should start your install.                                                              Joe < Data Miner >

can u expalin your problem

Hi,
simple format compatability issue.
you either don,t have the software on your computer.
Or the disks are unfinished or unfinalised, which means that there are no table-of-contents ( directory structure ) for windows to be able to understand the disks format.
Mike @ Compurepair.
Also the drive ( CD/DVD Rom ) may not be compatable with these disks. check your software read/write program, to see if the disks are supported.
