I have installed Win 7 on a Win XP computer as second operating system. After Win 7 had been installed the partition boot record of logical drive which win XP was installed on and bootmgr file has been created on the same drive, as expected. Does Installing Win 7 make other changes on the partition XP installed on? If original Win XP installation is restored from an image, is it possible to restore dual boot by just copying that bootmgr and rewriting pbs (partition boot sector) sector of the partition which Win XP installed on, after XP restoration?
I explain more:
I have a hard drive.
I have partitioned it -> After then logical drives C and D have been created.
I installed Win XP on C -> In this condition, partition boot sector (NTFS Boot Sector) of the C logical drive loads NTLDR to load operating system.
I installed Win 7 on D for dual-boot-> In this condition, the partition boot sector of the logical drive which Win XP installed on has been changed; now it loads BOOTMGR first, instead of NTLDR. And a file has been created in the drive which Win XP installed on: BOOTMGR.
I would like to learn if installing Win 7 as a second operating system for dual-boot made any other changes on the drive Win XP installed on and if I restore Win XP installation from an image of original XP installation, is it possible to restore a dual-boot just restoring the pbs to the situation after Win 7 installed and copying that BOOTMGR file to drive which XP installed on.
