You have to get a disk or the next one yourself to delete the boot file, and it will be very troublesome to get it yourself.

Win7+XP wants to completely uninstall Windows7,You need to deal with the boot menu of the dual system first,After removing the boot manager used by the dual system,You can format the partition where Windows7 is located normally。 Here's how:

First of all, boot to the XP system, and put the Windows 7 installation disc in the computer CD drive (if it is an ISO mirror file of **, you can use the virtual CD drive Deamon Tools to read and load the Windows 7 CD image to the virtual CD drive.

Secondly, click "Start Menu Run" in turn, and the command line window will pop up. Enter k: boot nt52 all force in the command line window, and then hit the enter key to run, it should be noted that k is the drive letter put into the windows 7 installation disc in this example, the reader needs to change k to his own drive letter according to the drive letter he put into the windows 7 cd.

Again, eject the Windows7 installation CD; Next, restart the computer again, we can find that the boot menu of the dual system Windows 7 system startup items and the early version Windows option are gone, and directly enter the XP system, which indicates that the boot menu of the dual system has been deleted.

Finally, in the rebooted XP system, it is now possible to manually delete Windows 7 files and folders such as program files, users, and Windows folders. If there are no other important files, it is easiest to format the partition where Windows 7 is located. Just uninstall Windows 7 under XP cleanly.

If you can't read the files on the disk, you can't get into the system.

But this thing is generated by default and placed in the C disk.,You can now rest assured that you can boldly delete the F disk directly.。。。

I'm a veteran tinker of the system, and I often do what you do.

My computer right--Properties--Advanced--Startup and Failback--Settings--

Just go to window7.

If you don't seem to be familiar with the operating system, just partition the hard drive from a new partition and install a system.

First prepare a primary partition under Win7 for XP recovery. Then boot the computer with the appropriate tool disc and restore the XP ghost image file to the main partition you just prepared.

After completion, there is no boot menu for the time being, and you can only boot to win7. It doesn't matter, after entering Win7 as a system administrator, copy the "NTLDR" and "three files (all in the root directory of the XP system) in the XP partition to the partition of Win7. Then run the command prompt and enter the following 4 commands.

Select "Command Prompt", and then enter the following commands in the pop-up command prompt window (press enter for each entry, if the message "Operation Completed Successfully" is returned on the screen, continue to enter the next command, otherwise please check whether the input just now is wrong and re-enter):

bcdedit /create -d "windows xp"

bcdedit /set device partition=d:

bcdedit /set path tldr

bcdedit /displayorder /addlast

Restart the computer after all the commands are run, and the boot menu will appear (note: where "D:" is the partition where XP is located, please modify it according to the actual situation).
