A couple of days ago I followed a YouTube video on dualbooting Windows 7 and Windows XP with Windows 7 installed first and I have done it once but my PC needed a reinstall of Windows because my partitions where messed up and this time after the Windows XP setup finishes copying files it will restart and then it will display and error saying something like, "A disk read error occurred press CTRL + ALT + DEL."  I have tried several times reinstalling XP and it keeps outputting this error upon reboot and I always have to put Windows disk in and repair it but then the Windows XP boot entry will not show up and there is a program called EasyBCD but I am nervous on mistakenly messing up or choosing the wrong option the current bootloader and then this time can't repair the bootloader from the disk.  I would really appreciate some suggestions and help on resolving this issue.

I multiboot XP, Win 7, and Win 10.


I install each in the proper sequence...XP, Win 7, then Win 10.


My basic suggestion would be to install XP first...then install Win 7.


If you have properly installed each O/S, even if you followed someone's instructions for installing Win 7 first...then you can use EasyBCD to change the boot order.  If you have not properly installed the O/Ses, then EasyBCD won't help.


In order for EasyBCD to work, you must have a recognizable Win 7 install.  It doesn't matter if EasyBCD is installed in XP or Win 7...as long as it sees a Win 7 install, it will work properly.


If you install XP first then Win 7...the Win 7 Startup Repair would normally correct most boot issues.  The XP Recovery Console, if used to try to repair an XP install that is dual-booted, will only break your dual-boot, making your Win 7 install unbootable..  Installing EasyBCD on the XP install would facilitate any repair caused by such.

I've posted this before.

Leap Frog will assist you in creating a bootable Virtual Hard Disk (VHD) for native Windows deployment with your Windows XP thru Windows 10 (Desktop and Server) or Mac OS X Snow Leopard machine. The VHD can be used as the running operating system on supported hardware without a virtual machine or hypervisor. This provides an excellent way for end users who wish to utilize the VHD technology and setup a multi-boot environment in Windows without having to "Upgrade" or repartition the hard disk.
