Need help deleting Linux partation

Windows is unable to read linux partitions, if fact it does not even see linux partitions. Since you installed with the option to use the entire disk, there is no available space that windows can see on the disk.

You have two options:

1) Resize you linux partition to create space to install windows. By doing this you will end up with a dual-boot system that can boot to windows or ubuntu. This is nice because if you ever had problems with windows, you can boot to linux to help repair it.

2) Completely remove/delete your linux partition

Despite what you choose to do, you will have to use the linux partition editor gparted. You cannot use gparted on mounted partitions so you must boot linux with the LiveCD. Then start gparted with the menu System-> Administration-> Partition Editor.

You the partition editor to resize or delete the linux partition. You will then have to create a primary ntfs partition for windows. Please review this website and look at the help section. It will help you if you are unfamiliar with the program gparted.

http://gparted.sourceforge.net/

If you plan on dual-booting window and linux you will to reinstall grub boot loader after you install windows. Steps 1-6 in the quick guide will help you to do this.

i did as you said but still neither my windows cd reads my hard drive nor my recovery cd runs in it. I am still in the same place.
i have a gparted cd and i guess i am not using it in right way. i can delete the linux partition but still i get the same erroe message saying "windows could nor find hard drive connected to your computer" and when i use the recovery cds it says "recovery cd does not support the pc format" same messages as above.
i did google search and found that fdisk can help to complety delete the linux partition but i dont know how to get to command prompt of fdisk in linux and also it is my laptop i dont have floppy. so i still need help with this.

Please use gparted cd to delete all partitions on your drive. At this point the disk should contain nothing but unallocated space. In this unallocated space create a new primary partition partition and format it as ntfs. For disk changes to take effect you must hit the apply button. After gparted performs these action you should be able to reinstall windows.

i have done that thousands times and i still get the same error message saying the recovery discs do not support this pc model

and when i try to boot from harddisk it says GRUB loading and stops saying err 22 coz i deleted the UBUNTU partition too.

Restore /fix master boot record

# Boot the system from the Windows installation CD.

# When prompted, press R to repair the system. Setup may prompt you as to which installation you want to repair. If you have more than one copy of Windows installed, be sure to select the copy that you are having problems with.

# At this point, the Recovery Console will load and will prompt you to enter the local administrator's password. Keep in mind this is often different from the domain/users administrator's password.

# Once you enter the password, you'll be taken to a command prompt. Type FIXMBR and press enter.

EXAMPLE

c:\> fixmbr

and pop in the windows CD and install windows

What i did was restarted my computer and put my windows cd in my optical drive and pressed R as u have suggested but it does no thing but says loding karnel and checking hardware at the lower bottom bar. no changes shows when i press any key in the key board. there is blue screen and bunch loading message at the bottom and at the end it says windows could not find harddrive. Thats all the same story. i am really frusted and about th break my computer. Any way i really thank you for your try

hello

Okay... You should format everything now and install windows and unfortunately it has to be done by booting through a floppy in this case...

Regards

That messages sounds suspicious.
It seems Dinesh is using such recovery CD-Rs delivered with special OEM versions of Windows sold with some brands/models of PCs like Compaq and so.
They expect to find particular sections of the hard disk containing part of the device drivers and other sw related to that computer.
By partitioning the hd using all the space on the disk that data has been wiped away.
The install process on the CD-R isn't now able to find that data and is claiming it can't recognize the PC (model) it expects.

In this case you should look on your PC manufacturer's web site, under "support".
