I am tring to format my hard drive on my Hp pavilian 551w,and I need to know what to do. I want to get windows millennium Me edition out and replace it with windows ep home edition on it.

Why? You could spend less money on a new computer on ebay.

you can run quickcad 8 from another drive and access your drawing, not quite sure how this has happened. I connect my old drive with windows XP and access the programme on it I can then run and edit this old programme from my new computer running windows 7 64 bit

probably 2gig but would be better to use just 1gig not knowing your processor size

hope this helps

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:

One of the options when installing Windows XP Home Edition *IS* the option to "format" the drive.

So, just start the Setup program.

If the hard drive was formatted on the MAC then the hard drive need to be reformatted using the Windows. If you format as a primary drive in FAT32 then the MAC can read and download files on this external drive so that a Windows PC or laptop can read. These files can be exchanged between MACs and PCs.

Fat32 simply means that your hard drive can only read files up to 4GB, format your external harddrive using file system NTFS then try to back up all your files again. Hope it helps you...

It depends how your tring to format it. If your operating system is running on the same drive it will fail. You would need to boot off another OS or boot of the XP / vistra CD and format it via the installation wizards.

Go into the system BIOS when the desktop boots (usually by pressing del or F10) Go to the boot options tab and follow the instructions to adjust the order of the disks. F10 to save and exit - it should now boot to the required disk

For zackmark96, your machine most likely is infected with viruses. You will need to format the machine and reinstall Windows. If you have files that need rescued, you can boot from a rescue CD. I recommend Hiren's Boot CD.

For Guest whose computer does not come on at all, I would guess that your problem is the power supply. You can try a different cord and a different outlet first to make sure those things aren't causing a problem. To verify that the power supply has a problem, it is easiest to take it and let someone check it for you. Places like Staples will do it for free I believe.
