I have win xp and win 2000 on hard drive I need to remove 2000.

the hard drive is the storage unit for the operating system , files and folders
when you install a new hard drive then format it , then install an operating system
best is now win 10 as win xp and win 7 are no longer supported by Microsoft and have dropped most drivers out of the system
to get the keyboard and any other pnp ( plug and play) units , you will have to go to the manufacturers web site for the key board , mouse , external hard drive etc, find a download for your model that is compatible with the operating system you are using and down load it

yes --
But you will loose all of your files and folders when you format the hard dive to install win xp
you cannot run 2 operating systems on the one hard drive unless the hard drive is partitioned ( in effect having 2 hard drives on the one disc) as it causes massive conflicts in operation
Why any one would install an out dated , unsupported operating system like win xp in place of win 7 beats me
of course if you insist in doing it you could always install and extra hard drive in the computer and run it as an extra hard drive and install the win xp on it and still retain all of your files and folders

The problem is that XPinstallation CD does not have a SATA driver, unless you have a SATA drive on adisk etc. and can install the driver when XP asks for a hard drive driver then,XP cannot detect the hard disk and therefore won't install XP. The FIX. Go into the BIOS anddisable the SATA drive (enable IDE emulation), this will make XP think it is aIDE/PATA hard disk. Then you can install XP normally. When Windows hasbeen installed then install all the device drivers (including the SATA driver),then shut down and boot up and got into the BIOS and enable the SATA drive.

What operating system? Windows? If so, what version? Linux? Mac?

It could be a corrupt system file or a corrupt section in the MBR of the drive. If you have critical data on the drive that needs backed up, then I recommend that you (from another machine of course) download a live cd version of linux to boot into along with an external usb hard drive. You can then mount your existing drive and copy your data to the external usb drive for a backup of data. I would recommend either PclinuxOS, Knoppix or Puppy Linux. Exit once backup is complete.

Next, boot your machine with either a restore disk received with the purchase of your computer, or if unavailable, boot to a system disk of your current operating system (such as windows xp, etc.). This MIGHT require a fresh install of the operating system - thus the reason for doing a backup of data first. If however, there is a bad sector in the drive's MBR then you're ultimately looking at replacement of the hard drive and then performing a restore or a fresh install of the operating system.

If you find this solution to be helpful, then please take a moment to rate this post. - Thanks.

If you have a valid Win XP Pro CD and want to install the operating system you'll need to format your hard disk drive. If you have allot of data on you're hard disk drive, (In Win 2000) Suggest you create a second partition within the free space of you're hdd and install windows XP Pro. Boot you're system with the XP CD. Pay close attention to the display screens. Follow the instructions for creating a second partition.
Format the new partition. (Quick). Install windows XP on the new partition. Once completed you can copy your personal data to win XP.
If you choose to keep the win 2000 partition and you do not wish to have a dual boot system than remove/delete the root files from the 2000 partition. These files; Autoexec.bat and Boot.ini. You're new XP Boot.ini should read like this;
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer
Once you're satisfied an no longer need win 2000 use windows diskmgmt.msc from the run command to delete the win 2000 partition.
Win 2000 uses a FAT16 where Win XP uses the FAT NTFS.

Cheers!

You probably are using Windows XP. With this error, you must re install your Windows XP operating system with your XP CD.

NTLDR is short for NT loader – a program loaded from the hard drive boot sector that displays the Microsoft Windows NT startup menu and helps Microsoft Windows NT load. So when it goes missing for some reason, your windows cannot load.
Cause:
1. Computer is booting from a non-bootable source.
2. Computer hard disk drive is not properly setup in BIOS.
3. Corrupt NTLDR and/or NTDETECT.COM file.
4. Misconfiguration with the boot.ini file.
5. Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32.
6. New hard disk drive being added.
7. Corrupt boot sector / master boot record.
8. Seriously corrupted version of Windows 2000 or Windows XP.
9. Loose or Faulty IDE/EIDE hard disk drive cable.
if there is attached drive ,remove the drive first before restarting the system if not then if you had access to another computer, copy the NTLDR and NTDETECT.COM which is available from the recovery CD which comes with computer. If you do not have the recovery CD, its available on microsoft site or is available from another computer using the same Operating System (Windows XP ). The location may be C:\i386\ntldr C:\i386\ntdetect.com use a bootable disc to restart the computer (the Win XP bootable CD or Win 98 bootable CD worked). After entering MS DOS mode, copy these 2 files to the C drive in the proper location. After restart, then pressing F10 on start up (used for system recovery ), then start the repair of Windows via system recovery This will reinstalled all Windows drivers and system files, while preserving all data on your computer.

dear Saratch...

you must trying re partition ur hdd with 3rd software like Ranish partition or partition magic, or you can try with fdisk from microsoft DOS with cd booting before you try to installed it with another system operation like win XP or win 2000
okey

cropp

you'll need to run windows setup again.
Insert the cd restart and when asked to start with cd click enter.

try to check whether the disk jumper is correctly placed then use another os to format the hard disk i.e os win xp
