dual boot Windows 7 64 bit with (pre installed) Xp 32 bit

[PakSpinWin]

Hi, My installation was FAILED!!! i have windows xp 32 bit pre-installed (in C drive), I was trying to install DUAL BOOT xp with Windows 7 (in D drive NTFS) using ISO image file of Windows 7 64bit ultimate (present in my HHD), i mounted the ISO file of windows 7 with the help of Virtual drive... The installation started normally but in the FINAL step (Finalizing installation) when system restarts to perform configuration etc, but instead of that i got message "Failed to install windows and rolling back changes"...

Important NOTE: Using virtual dvd rom, i mounted and install Windows 7 "32 bit" all right!!! There was NO problem at all of dual booting windows xp 32 bit and windows 7 32 bit on the same hard disk (on different drives)...so my question is Windows 7 64 bit cant be dual boot with pre loaded Xp 32 bit ??? or tell me how to do it please..i got 4 gb ddr2 ram and i want to run 64 bit OS windows 7 to utilize it maximum...


My system info;
Dell OptiPlex GX620 2.8 ghz, 4 gb ram, ATI 4350HD-512 mb
Hard disk space on D Drive is 25GB !!

Hello PakSpinWin, welcome to Seven Forums!


You cannot install a 64-bit OS while booted to a 32-bit OS you must boot the installation media using a DVD or a USB stick, the "rollback" message says you were installing from the XP desktop which is not possible except using the same bit-rate software.

If you wanted to install the 32-bit Windows 7 from a XP 32-bit desktop you could use the method outlined in this tutorial linked below to do a clean install of Windows 7.

ohh my bad...

thanks for quick replies.. but the problem was with my hardware...(my bad) my cpu does not support 64 bit, i came to know it later...

i am going to update my cpu from "Pentium 4 520j" to "Pentium 4 521" or something better in order to get 64 bit compatibility, today probably if i found one.
cheers!
