Windows 7: Remove XP from dual boot

Remove XP from dual boot

I'm currently dual booting Windows 7 and XP Pro. Because the fix that prevents XP from wiping out restore points in Win 7 won't work on this system I want to remove XP completely and just run Win 7. How should I go about this, do I just format the XP partition from Windows 7, and will the boot manager need to be altered to remove reference to XP?
I might, at a later date, do a clean instal of XP and then try the 'restore point' fix. If that works I will just use it for a couple of programs that won't work in 7. Many thanks.

First of all and just to put you online , I have a french windows, so I'm sorry for bad technical words translation.
To remove win xp from the boot screenwhile you are using windows 7
1- Right click on computer icon
2-Propriies
3-advanced system settintg ( up on the left)
4- start up and recovering==>click on setting
5-Uncheck " display systems during 30 sec" ( becrefullwin 7 should be the system that appear in the chosing bar
After a restar you can format the partition where xp is installed
good luck

Hi rachid128

Thank you, I understood you just fine.
Is it as simple as that? Only I noticed others doing the same thing are using BCDedit. Have you used that method?
Thanks

If you format XP on the first partition, it will make Windows 7 unbootable.

You need to mark Windows 7 active in Disk Managment, delete XP partition, then boot into the Windows 7 installer Repair console and run Startup Repair 3 times to rewrite the MBR.

If you want the Windows 7 partition moved into the lower address, use bootable Partition Wizard to move it over into the deleted XP space, mark it active then boot into Win7installer and run Startup Repair 3 times to solve multple issues..

Hi gregrocker thanks for response

This is the bit that confuses me. Presumably you mean disk management when booted into XP? When in Win 7, both Windows 7 and XP are marked as active, primary partitions anyway. But if you do mean XP then do I have to delete XP from within XP?

In windows 7 "disk management" one of the partitions will be marked as "Boot" and this is where the boot manager is , If it's in your windows 7 partition because you installed it first then you can simply format the XP partition, but if it's in the XP partition then a format will delete the boot manager and leave your system unbootable, you can try and move the boot manager files then rewrite it starting with using a tool like Easybcd or you can make a recovery disc in windows 7 then run it after deleting the XP partition, and that will get you back into windows 7

you can download recovery discs from here or you can make one within your own system by going to control panel / backup and restore and use the option to "create a system repair disc"

If you have XP running you won't be able to delete it. So boot into Windows 7 and follow his instructions.

After you delete the XP partition, restart with the Windows 7 installation DVD in the DVD drive, and run Startup Repair three times. This will rebuild the boot manager.

Have a look at this tutorial, it will explain how to use the installation DVD for startup repair.

Hello ickymay
Disk management says that boot is on Windows 7 (C:\) and XP Pro shows as Active, primary partition so from what you say I can format D:\XP from Windows 7. When I try that it says it cannot format the system partition on this disk.
I am still in disk management at this point. Should I come out of it?
I have made a system repair disk.
Thanks.

OK. I've now got it sorted. Once I had Win 7 active and not XP and rebooted I then got 'NTLDR not found'. I went into the BIOS and found that it was trying to boot from a removable disk. The CD drive had been pushed to third on the list. Once I made it the first again all went well, and as you say I needed to do three repairs first.
So, to all who got me sorted, my thanks to you. Fewer hairs now than when I started though.

Did you move your Windows 7 partiiton over, too? If you decide to do it later,, be sure to make a backup image stored externally so you can start over if the Resize/move operation fails using Partition Wizard disk.

When you get it all where you want it, make the Windows 7 backup image stored externally (and in a primary formatted partition ifyou want) to reimage the HDD (or a replacement) in 15 minutes, making reinstalls never again needed.
