How to format the partition that has Windows installed?

The HDD has got three partitions, C for Windows,
D and E for other files

One day, the Windows corrupted, and I have to install it again!

I put the Windows XP disc into the CD-ROM, but can't find any provided option to format the partition C.

Partitions D and E have stored important files, so I couldn't make a change to them!

I have tried to choose the option of "Install Windows to the selected Partition", but it warned me that if I try to install the Windows in that partition, it may not be stable...".
I think the partition C should be formatted before it can accept a new Windows.

Please help if you could!

If you follow the XP setup.....

In reply to: How to format the partition that has Windows installed?

to it's continuation you will find the option to format. Simply choose the proper partition for XP to install. Of course you do have a working backup of the other partition's data on an external source, don't you?

WHen ever I have a problem like this, I buy a new HD and then install XP on it. Then use the old HD for back up.

I now have a 20gb, 80gb, 80gb and 200gb HD.

Some day I may have to get rid of my 20gb, but on the other hand, I still have 4 unused sata ports...

I think I won't take this

In reply to: or

I think I won't spend money for the new HDD, as the current HDD is a brandnew one which was purchased three days ago!

The Windwos XP was installed just a few days ago, but then it corrupted. The partition C held the Windows, and the other two partitions have stored my personal data, and Partition C is the only option for the Windows.

Why not go back

In reply to: I think I won't take this

to a date that has god data? I alreday had to do that on my XP and it worked just fine.

no backup of data

In reply to: If you follow the XP setup.....

I didn't make any backup for the files in the two partitions, that's why I have got only one choice to install the WinXP.

More then one choice.....

In reply to: no backup of data

exists to backup your data before you format. In a machine that will not boot to XP, I will move the drive to another working machine as a second drive. From there I will access the needed data and copy it to a remote location (another local drive or network drive). A Knoppix cd can be used for the same result.

But answering your primary question again, I would ask why you did not remove the troubled partition when XP asked, then recreate it, format and reinstall XP? As long as the other partitions are not touched your data should still be there.

The Windows was installed in Partition C.
Partitons D and E were for Data Storge.

What I have been trying to do is, of course, reinstall the Windows onto the same Partition so that the important data in D and E won't be lost!

What can I do to remove the troubled Partition C?

I have tried to delete Partition C, but I can't, as the system didn't allow that!
Partition C is a primary partition, it is not the logical one!

just do this

In reply to: confusing

just reload xp over the top of itself and it will reload all the bad files to your C:partition

I have never tried to delete a "C" partition

In reply to: How to format the partition that has Windows installed?

when there are two other partitions on the drive altho i know the win XP OS/CD has the ability to delete a partition even tho it has the OS on it.

A workaround would be to use the recovery console to just format "C" (see the instructions at the bottom of this post) Then you can use the first set of instructions to re-install XP.

Be aware tho that "D" and "E" could also become unaccessible when doing this.

1=Set Bios to boot from CD/ROM as first boot device(Entering the BIOS and changing the boot order is not discussed here, you may have to refer to the computers manual for this).(For a clean or new drive the boot sequence does not matter)

2=Place the OS/CD in the CD/ROM drive and Re-Boot

3=Watch for the prompt to "Press any key to boot from CD/ROM" Press ASAP (Ignore when prompt appears on any reboot) (You will only get this prompt if there is an OS installed).

4=windows Setup (Loads Files)

5=To setup XP now press "ENTER"

6=Press F8 for license

7=To continue installing a fresh copy of windows without repairing press "ESC"(You will not get this prompt for a new or unpartitioned drive)

8=For a new or unpartitioned drive press "ENTER" (or you can press "C" if you want to create multiple partitions).

9=For a drive that has partitions, operating system or any data on it, you should press "D" to delete the partition and start out with a clean drive
10=Press "enter"

11=You will be prompted again, press "L"(You will do this for each partition) , Now you are ready to partition and format

12=Press "C" (Only if you want multiple partitions, Otherwise press "Enter"

13=To setup windows on the selected partition press "enter"

14=Select format NTFS with quick option, (Should be the top selection)

15=Press "enter'

16=Wait for format to complete

17=Computer will start copying files to the installation folders (this may take several minutes)

18=Computer will re-boot, do not press any key to boot from CD/ROM when prompted
19=follow the on-screen instructions to complete loading windows.

If you want to format the entire "C" drive Or the "C" partition where XP is installed, please try the following:
Set your BIOS to boot to the CD-Rom, {Procedure not discussed here, You may have to consult the Manf's manual.}
1. Start Computer booting from OS/CD
2. Choose Recovery Console (R)
3. At the dos prompt type: "format C:" (without the quotes)
4. If it asks for the "Administrator Pass Word", Type it in if you have one or just hit "Enter" to continue.
5. Commands that you can use, format (drive)/ Q (quick) FS/ (File system fat/ntsf)

can I try this only?

In reply to: I have never tried to delete a "C" partition

Can I type format C without additional commands?
When the partition C gets formatted, it should then accept a new installation of Windows; after that, I could choose to format C as NTFS or FAT32 using the Windows Install CD...

Yes that will work

In reply to: can I try this only?

after the format and you are back at the prompt just type exit, have the xp/os cd in the drive and follow the install instructions.

If you are still following this post

In reply to: Yes that will work

I did a test on one of my computers that has 3 partitions "C"-"E"-"F", I deleted the "C" partition using the XP/OS CD and was able to reinstall the OS onto the same space and it was assigned the "C" designation, all went well so I know it can be also done that way.

In reply to: If you are still following this post

From past experience, I see that if a Partition, let's say C, is deleted, it will just merged into another partition.

Or did you mean that you formatted the partition C instead of deleted it?

Collapse -
I deleted the "C" partition

In reply to: deleted?

Then I got the prompt If I wanted to install windows in the empty space, agreed, and the partition was automatically remade as "C" it then asked for a format.

Xp install

In reply to: I have never tried to delete a "C" partition

Re: xp install

In reply to: Xp install

First I'd try another XP install disk (or a copy of this one).
Then I'd try another PC.

Format C: Drive

In reply to: How to format the partition that has Windows installed?

From the tone of the various posts it appears that you are attempting to format drive C: in Windows or you have a vendor system.

Retired gave you excellant directions on how to proceed.
Michael gave you a way to save your data.

If this not a vendors system and you have a legal copy of XP You must boot the computer from the XP CD . This is the only way.
