How to format system drive

I’m running two OS on my system.
Windows 7 on Drive(partition) C:
and Windows XP on Drive D:
now i wish to remove windows 7 from my system, got rid off the BOOT thing, but the windows files remain. System wont let me format the partition C:
what to do?
any software that i can use, anything?
Answer #1
You need to edit the boot.ini file (could be hidden) on the D drive to look like this.
Since Windows 7 controlled the boot process it may have renamed the boot.ini file to boot.bak
[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=”C–XP” /noexecute=optin /fastdetect
Once you have done that use a partition manager like EASEUSPartitionMasterPro to set the D drive active and the other drive to normal (anything but active)
Reboot your computer and enter the BIOS to set your D drive as first to boot after your CD/DVD drive.
Incidentally in the above boot.ini example where you see C–XP ….. that is (or was) the name of my drive … you should put your own drive name there.
Once you get XP booting on it’s own you should be able to format the Windows 7 HD.
Answer #2
Have you already managed to boot into XP?
From there, you should be able to format C:
Otherwise, you will need to boot from a CD that has a partitioning program such as Hiren’s
Answer #3
i booted XP using “EasyBCD”
but still it wont let me format drive C:
EaseUS partition manager does not show any option of delete or format, for system drive or boot drive…
Answer #4
You format the primary partition and your system will no longer boot as that’s where XP bootsector is stored..

Answer #6
i booted XP using "EasyBCD"
sounds like your still using the 7 boot loader
C & D are on the same physical drive ?
if so you need to set the D (XP) partition as “active” and boot from that partition
is there a “boot.ini” file in the root of D ?
Answer #7
C and D are on the same hard disk.
i dont see any boot.ini
not even in hidden files
Answer #8
you could try using diskpart
on the desktop click start button.
on the search bar type in CMD then press CTRL+SHIFT+enter to run as administrator.
then the CMD will pop up as administrator. type in diskpart then press enter
now when you are prompted to diskpart type in LIST DISK plus the correspondent no. which you want to select.
once your inside the drive type in LIST PARTITION
you will see all of your partition
Now, select the partition you want type in SELECT PARTITION and no. correspond to the partition you want to format.
once you are in the selected partition, TYPE in FORMAT then <ENTER>
don’t forget to save any files before you format if you have any you want keeping
hope this helps

Solution..Format and reinstall.. sounds the best option for you !!!
Answer #13
can't i create a boot.ini in D: then?
set D as “active” and try using EasyBCD to create boot.ini on D
or with D set to “active” put in your XP disk and go to command prompt
then type
fix mbr
fix boot
Hiren’s BootCD has tools to change the “active” drive if needed
Answer #14
