Windows 7: Install Xp After Win 7 64 Bit

In XP disk management, if the drive letter for Win7's partition is removed, it will not be accessible in XP .

An unintentional access and screwing up of the of the restore points is a mere possibility ... coz they are not that easy to browse to.

Many a times some system files modifications made my system unstable ... I then boot Ubuntu via boot menu, replace the modded system files with the original ones (I keep a manual backup of a system file before modding , as well as image backups, to a place other than C drive), and boot back to windows 7 . So, the writability is not for bad always, IMO :)

But I don't understand why! Assume you start winxp using bios f12 key. While running winxp you edit some win7 exe files and delete some win7 dll's. How does win7 know what you did that and perform a valid "system restore"? i'm very confused

winxp doesn't even know that you boot using bios f12.

I have not really bothered to worry about why XP doesn't cause 7 restore points to be deleted when Dual Booting via BIOS. I'd guess its due to separate HD's and boots.

I troubleshoot in the busy comments section for Dual Boot Installation with Windows 7 and XP which has over a million views, and haven't seen it come up there.

XP mode did not work for this particular application, all my other XP software runs happily in XP mode. I will have a look at the Virtual options, my old machine did not support Virtual operation so this will be something new to try.

This raises a question for me, which virtual software to try first on Win 7 64 bit?

@gregrocker:
Information for advanced users



Consider the following scenario. A shadow copy is created on a volume in Windows Vista or in Windows Server 2008. Then, you access the volume from an earlier Windows operating system. In this scenario, the shadow copy is deleted. You experience this problem if one or more of the following conditions are true:
  • You use Windows Vista or Windows Server 2008- based system in a dual-boot configuration with Windows XP or with Windows Server 2003. In this scenario, any restore points that have been created in Windows Vista are lost when the computer is started in an earlier Windows operating system. Additionally, shadow copies that were created in Windows Server 2003 are lost when the computer is started in Windows Vista or in Windows Server 2008.
  • You create Windows Vista restore points on an internal hard disk or an external hard disk. Then, you move the hard disk to a computer that is running Windows Server 2003 or Windows XP.
  • You use an internal hard disk or an external hard disk to store Complete PC Backup files, and you then access the volume from either Windows Server 2003 or Windows XP. In this scenario, all earlier versions of the backup files are lost. Only the most recent backup files are still available.
This problem occurs because the volume snapshot driver that is included with Windows Vista and with Windows Server 2008 uses disk structures that are incompatible with earlier versions of Windows. Therefore, the earlier operating system deletes Windows Vista shadow copies or Windows Server 2008 shadow copies together with the associated restore points. This behavior occurs because the earlier Windows operating systems do not recognize the new disk structures.
---------------------------------------------------------------

Windows 7 volume snapshots are deleted in case you access that volume from windows XP.
